The Ford Escort RS Cosworth is a rally version homologation special of the fifth generation European Ford Escort. It was designed to qualify as a Group A car for the World Rally Championship, in which it competed between 1993 and 1998. It was available as a road car from 1992 until 1996. The powertrain was only fitted to this version of the Escort, a longitudinally mounted Cosworth YBT, a highly tunable turbocharged 2.0 L (1,993 cc) with a bore x stroke of 90.8 mm × 77 mm (3.57 in × 3.03 in) Inline-four engine[1][2] which had an output of 227 PS (167 kW; 224 bhp) in standard trim. Tuning companies have achieved power outputs in excess of 1,000 bhp (746 kW; 1,014 PS)

I can't get over how professional your videos have become. You've done away with that irritating background music and gone straight in with close ups of the work being done. Detailed filming showing your work, good points, mistakes, things to look out for. These videos are good ... VERY good!

[@ahillvfr]

Before you pull the head off I would check the water jacket parts of the inlet manifold, I used to be a technician @ Ford in the late eighties/early nineties and had quite a few vehicles where the antifreeze had solidified from having too strong a mix and blocked the chambers to the cylinder head from the inlet manifold causing the same sort of fault.

[@mk3escort84]

Well done mate on the diagnosis. Love watching your work. All the proper checks. Loads of patience . So happy for you finding the issue keep up the good work

[@jamesbrannan7449]

Just goes to show always check the smallest simplest stuff before going to the bigger parts, you do more work but can save so much money, great solve 👍

[@Adam151082]

Thanks James

[@krusher74]

its never just that, if that had enough gunk in it to be blocked there is plenty of crap in the rest of the system. it needs a full clean/flush. Use somthing like holts rad flush. The cooling section of the turbo will be partially blocked, you dont want to kill the turbo next.

[@andyspinks9996]

Good point. Got to be coming from somewhere

[@tedted5767]

Love the passion you have for these cars. Such a good feeling when you have found fault.

[@Adam151082]

Thanks Ted

[@markcozzie]

Adam have you seen in the comments someone impersonating you asking them to DM?,just wanted make sure you aware of this??

[@blueonblueracingnova]

The best way to check a radiator isn't blocked is to the the car run up to temp and feel the rad all over to make sure there is no cold spots , filling it with water means nothing it could be half blocked and would still flow water from a hose pipe fine . I wouldn't be too worried even if it was the head gasket its a £200 job at most if your doing it your self . at least its hopefully sorted now though and another job ticked off the list

[@SecretOfMonkeyIsland784]

I dont know squat about fixing stuff on cars, but i like Cosworths so this helps me learn a little bit and enjoy seeing a project come together as well

[@theshrew69]

That's a great find not many people would've even looked at that.

[@rexim3530]

For the cutting out issue. Open the fuse box and feel for hot relays, most likely fuel pump and then check fuel pump for issues/blockages. Keep up the great work!

[@markcozzie]

@RealAdamSmithOfficial SCAMMERS

[@Taz6688]

Fuel pump relays on Fords were a problem, looking fine, but opening it up you could see the broken trace and burnt board, having said that I'll bet almost every electrical connection will be corroded to some extent, electrical contact cleaner and checking for broken wires,

[@shaunwilson-seabrook]

Definitely speak to Paul , I’m sure he’d be happy to pass on some advice to help . You could still do the work just be nice to know exactly what the issues are . Great videos . 👍🏻👌🏻👏🏻

[@TheVeiledSecret]

Hello Adam From what you describe as the car driving for a very short time ie 5mins and simply cutring out i had the exact same problem on an Escort Cosworth i used to own. I was diagnosed as the Crank Postion Sensor and this was replaced to which the problem was immediately rectified .. the air intake sensor was also replaced as well as a minor precaution. Hope you get it sorted soon and resolve the issue 👍

[@deejayjay4066]

The cutting out issue…..I heard of similar on I believe a Sierra XR4i. Someone had plugged a relay intended for heated rear window into the fuel pump relay position. Hence after so many minutes the car would cut out as the relay timed out. Worth a check if not done already. Thanks for the videos 👍👍

[@JohnJones-wo1bc]

Love that car. They were all the rage when I was about 15, and they still look super cool to me! You're a lucky guy to have it!

[@TheDickieP]

You absolute legend. I’ve been loving this series. I’m on this series ‘like a Geordie on a cossie’

[@davebrown7527]

Well done, a lot of people would have had the head off first before realising the banjo bolt was the problem 👍🏻

[@elliotdavis4641]

Well done mate, hopefully this will sort it. This series is going to be amazing love Escort Cosworth

[@markcozzie]

@RealAdamSmithOfficial SCAM

[@edwardboyle808]

Adam love the videos interesting informative and definitely fun - reading through the comments posted “try this-do that” stick to the way your doing it with the fault finding, you’ll feel a lot better in your self knowing you’ve done it and solved it yourself… bonus you’ll get to know your baby even more so - you’ll crack it 🔧👍

[@adamweston4152]

I had a escort estate mk3 years ago and it would run for a few minutes and cut out and eventually found out that the crankcase breather pipe was blocked and after cleaning it out it solved the issue and ran fine so maybe have a look at yours Adam, I know it's a longshot but worth a look.

[@davidhaygarth648]

Great news ! I would have never suspected that. Saved yourself a fortune.

[@garagecedric]

I used these kits which detects exhaust in the coolant, with a blue fluid. Worked for me to find a leaking head gasket, less fun that the engine block wasnt flat enough to keep boost in there. Hopefully it works now though:)

[@manolisconstantinou8789]

Big Paul had sold him this car so he can work on it himself and create content with it . Defeats the object if he gets help from the outsides. Advice is all he might recieve

[@mickmiller9936]

Perseverance always pays off, well done Adam. Plenty professionals could have misdiagnosed that by not having the patience to cover all bases. You’ll have this mint in no time 👌🏻.

[@jaredwoodward919]

Good work chap, keeping another cossie legend on the road.

[@stevo5222]

I'd change the crank sensor as already mentioned, not that expensive and was the fault on mine. The fuel filter if blocked can cause the hose to be sucked flat starving the fuel system. That also happened on mine when the car was 2 weeks old!

[@c111prs]

They always ask when was fuel filter last changed before you go on most dynos , again a good call to change this item ,, that might not fix issues but certainly worth doing

[@craigdavies9500]

I love how you aren't afraid to take things apart Adam. Also love your fault finding skills, Keep on with the cracking videos.

[@Adam151082]

Thanks Craig 👍

[@mfordy1056]

Good work tracking down the problem. You must be used to the taste of anti freeze by now though……some fittings for your airline next time perhaps. Good luck with the car.

[@darrenrevill8664]

Nice job there. Good to see your doing your homework and not just throwing parts at it. Try a different furl pump relay. My mate had a Sierra with a similar problem. Ended up being that the relay had gone before and he grabbed a spare knocking about. This ended up being a timed heated window relay !

[@c111prs]

What a guy, what a find , I’ve a new fuel pump loom and relays to fit Adam ,,.so when your ready pal ;) one might help your engine cutting out problems, but even if not ,,still a decent upgrade not just a parts chuck

[@MaddMattsGarage]

Awesome work Adam, late to the party but was saying to the TV check the turbo lines as they suffer the worst metal electrolysis corrosion ever, first time I saw it in person was my 97 Z32 300zx twin turbo engine rebuilding it. However I dig your passion and feel for it, I am reliving my cosworth/max power days vicariously through your videos. Cheers Mate.

[@SkipperDannyD]

that's mad how you worked back like that..good detective work! I'm 42 and never done more than change a tyre but i feel getting a car to fix now haha! I've learnt that there should usually be fluids, so try air!

[@neildonaldsonlotusexcelresto]

Well done Adam... I thought the fact that the expansion tank level was not going down pointed to a blockage rather than the cylinder head gasket....

[@Daniel-wb4lr]

When i was younger i had an 82 xr3 overheated massively, blew head gasket. I got so down with it being young with hardly any cash i did the water pump, rad, head gasket all on my own on my drive then sold it. I just lost all interest it finally beat me. Just to add im not a mechanic so god knows how long all that lasted

[@zoltankerenyi6614]

Good job mate! Love your videos and love your Cossie. Wish you a lot of happy miles and twisty corners 😁 Cheers from Hungary!

[@marklockwood8386]

I only subscribed a few weeks ago I absolutely love your channel not kidding I am 52 and your restoring the cars that we dreamed of in the day its magical

[@ricksworkshop748]

Have you checked the thermostat? Standing 6 years it can easily be stuck. Test it in boiling water. The turbo pipe would not stop flow through the radiator so i recon when you removed the stat you knocked it enough to free it off. I used to be a Ford RS tech. 🙂

[@markblacklock588]

Well done Adam your persevering is paying off, one job at a time your getting there

[@user-kl6yz1bd1y]

your timing belt also looks like it needs replacement. you can tell by the stripe markings in line with the teeth I would have replaced that. and well it is so incredibly easy to swap those belts but you need to do it the correct way and that is also not difficult whatsoever great repair by the way cheers you got a great car

[@hutchy1111]

Nice one Adam. Hope the 3 door isn’t getting jealous! We still need some content on the 3 door 👍

[@ColinP46]

I had a GTi that I got cheap as it kept cutting out. It turned out to be a dodgy fuel pump relay which was just making contact and no more. Car used to run fine but after about 5 mins the vibration caused the contacts inside the relay to fail. It’s a cheap thing to check. Good luck.

[@bishbashbosh-j6z]

thoroughly well diagnosed, if that's the most you've been into in the engine bay then you're a natural. Engine bay looks well looked after, even coolant reservoir looks new.

[@tricksmoke]

Good investigating Adam, for the cutting out issue there is a Guy up your way who has a business called intelligent Auto, he'll sort it .

[@tracieoliver2307]

Adam check the crankshaft position sensor as these tend to mass up and cause the cutting out issues! I have seen many that do this and there is no ryhme or reason but they run for 5 mins then cut out! then run for 5 mins and cut out! They can and will stop the car starting eventually!

[@TidyRC]

I’m so thrilled for u mate. Ur dream is still intact 👌🏻👍🏻

[@andrewonmyway8184]

What a great be of investigation. So happy for you you found a cheap fix even though it took time. Great work!

[@slotsoffun2540]

I remember ordering my escort Cosworth bran new . The several months wait was nail biting . I picked it up 10am did not sleep all night and remember the dealer going through it all bla bla bla and all i wanted to do was get out of there with it and show it off . Insurance was £4200 and that in 1997 was mental . any way cut a long story short . I think i was out of there by 11ish and by 12ish I crashed into railings next to the train station full front end job .. was back on the road several weeks later after a 6 grand bill from fords but was never right kept popping drive shafts for months . love to know where she is now .

[@mattyj624]

Great video mate, I had a mk1 golf that use to run for 10 mins then cut out! & after alot going round in circles it was shit in the fuel tank & pick was getting blocked stopping the fuel flowing, so might be worth a look check eh.

[@paulriggers1558]

the weak link on escorts of that era were the fuse- boxes, the printed circuit used to burn out around the fuses + relays. i replaced loads in the day, but i wasn't a RS dealer, so didn't do any cossys

[@johntheman2006]

Brilliant. Good thinking testing every part of the system for yourself and well presented.

[@the3doorking293]

SUPERB CONTENT ADAM. Had me in stitches with your comment, "done as much work as a Yummy Mummy from Newcastle" 🤣🤣👍👍👌

[@ascno1970]

well done adam, youre definirely a man who tries & succeeds 🙏🙏👏👏

[@sarcastixx74]

If that cars been standing for a good length of time it'll defo be needing a full flush from heater matrix to expansion tank. Using a water hose through the rad can be used to detect full blockages but it doesn't emulate what it's like when the system is running normally (under pressure) so it'll need a good heavy blast through. You can always check for cold spots when it's up to temp by hand. As for the cutting out, cam position/crank sensor or fuel pump as a few others have pointed out. Only other thing could be electrical, if it was cutting out at the exact same moment after firing it up then it may be the immobiliser kicking in for some reason? You're on the right track though, that car is gonna be a minter when it's done!

[@seanhammond4527]

Glad you have found it Adam that’s one of the list of the to do list 😊

[@chisharpe3304]

well done for going through all of these items. Old cars are a bastard sometimes. thanks for the update been waiting to know what it was.

[@alanmitchell6302]

Worth taking your time and checking the basic things first Great work

[@matthewlock5833]

A rusty banjo bolt would have been my last guess. Top Work.

[@alanchurchill7305]

Brilliant deduction Adam great that everything was accessible,hope it sorts it for you mate ,your working through the problems one by one ,it will soon be on the road, wishing you all the best.

[@Adam151082]

Cheers Alan

[@johnmccarthykarting]

Can't beat a fast ford your a clever lad love the Cossie content

[@stevewilliams5428]

Nice work. The corrosion line on the water pump was because the car sat with low coolant and had air in the system. It was exposed to the air. Likewise the banjo bolt you replaced. The other banjo bolt was fine because it wasn't exposed to air. You may still have to remove the head for the same reason.

[@RATADATUAVELHA]

great man! love the work and the almost no-editing videos.

[@mickeyflood3808]

Quality vid. Superb find saved yourself a fortune 🤞🏼 can’t wait for the next video

[@gvn-xk6eq]

Head gasket is not as scary as it sounds mate you’ll enjoy taking it apart and learn a lot also be careful with ingesting anti freeze it’s deadly

[@simonnorcliffe5877]

You are so good with cars , a headgasket 😊is a stroll in the park for you to repair 😮😊😊

[@melwebb8485]

Good diagnosis also you learn about your car as you go along.

[@hongkongstuey]

I'd have never have guessed turbo banjo bolt!!! Great find, fingers crossed it gets simpler now.

[@AndrewNeilBaird]

Right so ive just watched 30 seconds of this, and even before i drove a ford like that ( years of the road) i would be installing a new thermostat and making sure the water pump wasn't faulty. We used to get even nearly new fords with duff thermostats and water pumps in the workshop.

[@c111prs]

Whoever said fit a New fuel filter was a good call and we’ll worth doing regardless

[@paullinfoot6017]

Crank sensor mate well done finding the water issue

[@tbdogfosters]

great diagnostic mate glad you found the problem 👍

[@Cordfosworth]

Chuffed that you sorted that mate... the old process of elimination rather than just throwing it into a garage and spending lots of £££

[@sxrory]

Always the last hose you check 😂🙄. Lovely car congrats

[@stilostan-the1st]

You look soooo happy to be working on the escort Cossie, I would be too if it was my own car, good luck sorting out the coolant system

[@shanewaller2864]

Hi Adam.i never used to run water through my turbo , it would keep the engine cooler ,all I would do is warm the engine up before taking it for a blast and then letting it cool down before switching it off.

[@valvemonky4734]

great fined makes you wonder the reason it had a new water pump on was for the very fault you have just fixed but wasn't picked up by the previous owner

[@revveduprides5125]

Fantastic vid. Makes a lot of sense what you did there. I’ve got the same problem on my 3dr and the bolt was the only thing I didn’t check. I know what I’m doing this weekend and it’s thanks to you. Awesome and look forward to seeing the next update

[@staffordshirebullterrierli7411]

That red marker on your 13mm spanner is a good idea mate, Ive always used black pvc tape on my 10, 13, 15 and 17mm sockets 😀

[@marcuss1754]

smashing job mate, absolutely smashed it

[@jtekdryice]

Adam mate if it still overheats pop a new expansion tank cap on. Only a tenner and solved my overheating issue. You can test if you have a pressure guage. Mine wouldnt hold any pressure so water overheated!

[@ade-1772]

nice work and havent seen the end but i would say you have solved the problem

[@brettc1169]

If the head gasket is blown, it usually blows the bottom of the radiator out (It bananas the bottom out) 😊

[@philhyde2635]

Nice detective work there Adam. I would drain and flush the existing antifreeze, and change to Forlife. Good luck.

[@bowmosexual]

Great watching you dood, looking forward to the nest one!

[@Jay-zq3sy]

Some proper fault finding that good job mate

[@tim8115]

When I was a boy I had a die-cast scale model of this car. I think that’s the closest I’ll ever get to owning one 😢

[@mrcrazyjonpresents4312]

I can see why they got rid of it know one problem after another Oh well keep with it i'm sure after a great wedge you will finally get it sorted

[@Kalus_Saxon]

4:46 while your there changing the water pump with all that off few more bolts the heads off then you can inspect the valves pistons sleeves and stick a new head gasket and know it’s all sweet when you put your foot down… P.s… it’s been over heating so I’d change the head gasket as standard as it could be weak already..

[@Kalus_Saxon]

@RealAdamSmithOfficial oh what do I win ?? 😃

[@Coolbreeze6132]

Nice work mate! Another issue fixed. Looking forward to seeing you take it for a proper run

[@Gmh6477]

Glad you found it, poor guy who owned it last obviously put a water pump on and paid god knows what else trying to figure it out… First job for the cutting out would be remove any aftermarket immobiliser or alarm some had a timed ignition cut function also check for a “turbo timer” relay which might be dicky

[@kevinmchale6637]

Well done adam good detective work there pal

[@catxls1835]

Well done on sorting the overheating problem. Maybe the engine was cutting itself off when it was getting hot, or evaporating the fuel before getting to the cylinder. I have seen that before and it was actually a leaking fuel filler cap and the fuel tank pressure just dropped. Just a thought but I'm sure you'll get it sorted. Lovely looking car!

[@Charlton2010]

Head gasket is not an expensive job at all if you’re doing it yourself, it’s just high labour intense, by the way love the car

[@mark2too]

Superb Adam, step by step diagnosis, until you found the issue! Standing disease is a car's worst enemy.

[@brentleajunction]

Good luck with the car Adam hope this has sorted out the heating on the car onwards and upwards mate

[@garyhenschke7330]

Hey Adam on another subject, when will do a follow up video on Auto Bionics Sierra Cosworth V6 Twin Turbo Project… Good plumbing job

[@andrewswinglehurst8102]

Cracking work on a absolute belter of a car

[@Se7en983]

Good work make can wait to see her running properly

[@richardyoull528]

The thermostat that you removed is the wrong one. The one you have removed is a 2wd style one. The 4x4 has a dual function and without it will over heat. Also you should be able to blow straight though the turbo water cooling pipes

[@turboslag]

Always use the simplest thing first mantra. In this case, if it was the head gasket the rad hoses would be very hard with the engine running, look for water in the oil or oil in the water, next, thermostat either sticking or faulty and not opening, next, water pump. I'm not sure of the type of pump it is but the impeller may be spinning on the shaft or it could be seized. Blocked rads are unusual. Also, check that the cooling fan works.

[@Dalamain]

New to the channel, I really like the way you make the videos feel like we are there with you fixing the problem, nice job mate - subbed!

[@TezlaByte]

Thank you for the update. I'm thrilled to see such a "huge" problem being solved by so little :D I was cheering inside! :D And thank you for the more "explain it like I'm 5" :D I really like it. A little hard to keep up with your accent some times 😅😅 Greetings from Denmark
