[@tlcarak740]

The amount of effort given to getting camera shots is much appreciated. The little things like framing up a connector to show you pulling it with a pick really helps.

[@Flavio617]

Agreed

[@roninstickersonetsy9510]

“Super easy barely an inconvenience “ I got the pitch meeting ref 😂 good one Charles

[@HumbleMechanic]

Hell yes!!! I love how many of you guys watch Ryan too. Haha I don’t watch much YT but it’s often him

it's my second favorite channel after HumbleMechanic of course Haha😄@@HumbleMechanic

😊

[@chrisr5561]

Charles makes this look easy. I did this job on my 2016 GTI back in 2020. I don’t want to replace the water pump ever again.

[@TassieLorenzo]

Give it 60k miles and it will start leaking again, though?

[@MrTheHillfolk]

​@@TassieLorenzo Yup. Plastic junk.

[@MrTheHillfolk]

​@@TassieLorenzo Get it thru FCP though, at least its covered by their lifetime warranty and if youre DIY youre just out labor on replacing it again in a few years.

[@gregzoller9003]

Got it! Step 1: Disassemble front half of engine. Step 2: Replace water pump/thermostat. Step 3: Do valve job, timing chain, and new pistons while we’re in there Step 4: reassemble everything 😂

[@ZigArrok55]

Agreed. I did the one on my 2015 GTI about 2 years ago. I only struggled with 2 things. That darn triple square bolt holding the manifold bracket on, ( I don't have a lift and was doing it on ramps so I had to Take it off and put it back in from the top which I DO NOT recommend), and the bolt that holds the belt on because I didn't have the crankshaft tool. So the belt did not get replaced. My belt looked ok but I definitely wish I had done it for the peace of mind.

[@Replayss07]

As a VW tech, I appreciate you making these videos to give the community more confidence in working on their VWs and also giving the other part of the community an understanding as to why it's never cheap to bring their VW to a shop. I'm glad 90% of the Thermostat housings I do are under the warranty extension. I have this job dialed in to about 2 hours because I've done so many

[@alexbrewer1745]

Same lol also a vw tech these and the 1.8-2.0 turbos

[@Noname23489]

I took my s3 in for leaking coolant and balance shaft seal, does it surprise you that they only changed the water pump itself under the warranty extension? I would of thought they would of done both at the same time the plastic thermostat housing and water pump

[@Replayss07]

@@Noname23489 Warranty will only pay for a failed component. If one is leaking and not the other, they can only replace one. However, depending on my mood or how bad it's leaking, I'll just say both are leaking and replace both. But generally you can't replace both just because

[@D3nn1s_NL]

Does volkswagen also cleans it before replacement? I’m just curious because after the repair they did for me i have more leaking stuff under my car then ever before. But it has come to a stop so my assumption is that there was still coolant or anything else left there and while driving it came down?

[@Replayss07]

@D3nn1s_NL What do you mean clean it before replacement? I can't speak for everyone. The people working on your car are human. There's not a set process of doing something like being a robot. I couldn't tell you if anything was cleaned or not. I know I clean up after myself when doing a repair

[@dw1508]

Alot of people will watch this video just to confirm why they will pay someone that's done hundreds of these to do one more 😊 mine is still going strong at 64,000km hope it lasts many more

[@ChokeyChoke]

So true. I noped out at about 5 minutes into the video

[@jillianvanliew]

Having all my VWs need a replacement water pump, it’s cool to see this repair. I had no idea it was so involved 😩.

[@HePBHuq]

"You still got plenty of Rizz left to not be dogwater" killed me. Great video! Love your content. Keep up the good work, Charles!

[@KingMechanics]

I run a mobile shop in Atlanta and these random videos really help with pricing jobs.

[@atubebuff]

Charles just wanted to thank you for this video. After doing it all right EXCEPT for the union which dumped my coolant and my tendency to be "delicate" when installing most parts on VWs, I omitted to "nudge" the pump towards the oil cooler and ensure the union was squarely seated. The boroscope pic of coolant flowing out of the oil cooler side of the union really messed up my day. Thankfully your technique saved the (next) day. Cheers!

[@renerobes30]

Watching this video was deja vu. I'm replacing the PCV valve on my German SUV. The items that needed to be removed/unplugged is crazy, plus access was very limited. I can imagine the labor charge for this $129 part install. You have my deepest respect for making these repairs look easy.

[@BobWilson-t1i]

Sweet video. I’m not a mechanic and was able to swap my pump and decarb my injectors all from your videos. Car is running great. Saved $2000 off labor.

[@adanramirez1663]

Ok, I ve seen this video like 55 times, I think I memorized it, I ll get back to you guys in 1 week once my 1/4 torque wrench arrives.

[@synth8282]

been watching all the old videos so catching a video that's been up 2 minutes and not 6 years feels mad

[@joshlismore]

You'd really hope VW use these as training aids. Very thorough and detailed as always.

[@Replayss07]

As a VW tech, he does have a ton of good videos that I've watched to get more comfortable with what I'm working in. That being said, these thermostats are so common amongst every ea888, vw techs don't need this as training lol I've done 3 of these now in the past week and a half. I even took a few things away from this video. I've always taken the fuel hose off of the pump instead of just pushing it out of the way like he did , as well as usually leaving the top coolant hose on. Just a couple things that'll make life a tiny easier pulling the manifold off

[@LansaDiag]

Had the joy of doing this on a 1.8TSI Octavia once (same car as a Golf 7, just different body style) Absolute horrendous job.

[@spadman82]

I’m grateful for videos like this! The frequency of maintenance on my 2018 Beetle 2.0t gen 3B is a real downer. Coolant (very recent) leak sprayed on the big radiator fan and killed it. It stayed running and killed the battery. $180 for the pleasure to repair that! Now a water pump. Another $270 for that alone.

[@aldinnukicic3458]

Pro little tip, if your doing this job and have relatively big hands like me lol, there’s 4 tabs and one connector on the radiator fan, pop all the loose and boom, lots more free space. Over at the vw dealer I worked at, I learned this trick out pretty fast and it made the job super easy especially since I had a lift, that way I don’t have to remove the intake manifold. That goes for both the new and old gen, just on the old gen you have 4 t-30’s holding the fans in, but they are super accessible. I did do this job just recently on a 15 GLI from home , had it out and replaced in about an hour. If your planing to do this job and want some more room, remove the fans, you’ll thank you me later😉

[@AngusMcDangus]

In the process right now and that fan assembly takes up so much room. Was wondering if that was a workable strategy. Thanks for confirming!

[@jameshaulenbeek5931]

I tried this on my R, but I couldn't get the fan assembly out either up or down - it kept hanging up on the radiator and intercooler bungs.

[@joshmorton755]

I so appreciate you and Paul! I know it was just you in this video, and Charles, thank you! My car has been broke down for the past month. I knew it was my water pump and this video made my life so much easier, thank you thank you thank you!!!

[@94Poptart]

Just bought a mk7.5 gti, I appreciate this video so much for the day I have to do this!

[@Unreal_Tiger]

This was one of the cleanest car DIY videos I've seen! amazing job!

[@dennisstafford108]

Because of this video I checked into my low coolant and got my water pump done by VW with one day of warranty left!

[@Messier87_M87]

New video!!! So thankful!! Appreciate you Charles! These videos are super fun to watch and you humor is icing on the cake. You come across as a very positive person, and would be great to hang out with in the shop.

[@matthewrlawton57]

I work at Skoda in the UK and we just take front end off and leave the intake way faster and easier less chance for something to break/ go wrong or left disconnected

[@kiwiman9754]

Can you see the pump or is it all then by feel? That would be difficult if never done before.

[@jameshaulenbeek5931]

​@@kiwiman9754the 3 upper bolts will be more "by feel". If you can get the fan assembly out, you'll have plenty of room. I wasn't able to on mine, but I did have to de-carb the intake anyway.

[@tylergow3026]

I have done quite a few of manifold removals, I dont like disconnecting the top coolant pipe or the fuel line. If you loosen the 4 T30 bolts on the valve cover for the coolant lines (2 under the wiring harness, 1 near the oil fill cap, and the other on the side towards the vacuum pump) it gives a bit more movement without having to make a mess. I also find it easier to remove the 2 bolts for the harness bracket rather than removing the connectors from them, gives more room to disconnect the vacuum line under the manifold and leaving it on the car. Great work as always.

[@Replayss07]

If you're just doing the manifold, then it makes no sense to remove the coolant hose, but you already have the coolant drained for this job, so it's kind of worth it. It makes putting the manifold back on a little easier imo and only takes a second to do. Tried it the other day. I normally don't drain the coolant first, I let it all come out when I disconnect the hoses off the housing. Then I took that coolant hose off for re-assembly. And taking it off how he did will allow you to move the entire hose out of the way because the one end is the middle hose on the thermostat housing. That way, theres stuff in your way at the thermostat housing

[@redsunrx7]

You happened to release this video while my car was on stands awaiting the parts to do this job 😆 Fantastic work Charles 👏 very concise and detailed instructions. Really very helpful and detailed. I referred to a few other videos as well (Paul's etc.) but this was the one I used the most for the job.

[@JamesLee-dr3nq]

the part look all are plastic, when the temperature like Australia very hot day can up to 42 degree C , so the pump seals can easy leaking water when expand and contract and need change all time the water pump and water hose. So far the video very clear to show me how do change . thank you so much! love you..

[@Supaasian14]

As a Subaru apprentice I really apprentice these awesome and informative videos on other car brands!

[@jamesspiroff9117]

great video. I just did my GTI mk7 for the second time. 60k now 90k. You do not need to remove the intake. Undo a Couple plugs, the throttle body, the hoses and then slip out the radiator. Five bolts pump is out.

[@goingsomplace6014]

"You'll never guess where that went..." was so casual I literally laughed out loud.. lol as them kids say. 🤣

[@danh3008]

i like watching your videos because it reminds me how much i hate working on german cars. Keep up the great work!!

[@Darthvolvo]

Watching this review was super easy, barely a inconvenience.

[@HumbleMechanic]

Don’t forget to make your water pump bolts tight

[@bluej511]

What's up Charles. Those coolant funnels are honestly a God sent. Never seen some a simple and genius design. I used to run it with the funnel in so it would bleed so quickly.

[@rallyartman621]

Thank you for this i just bought a 2020 tiguan with the same 2.0 liter engine and becuase of these in depth diy videos im not afraid to work on this thing after its out of warranty. I want this thing to go high mile like my fiesta st did. Shooting for 250k without breaking a sweat

[@shan3_o]

nice video, great details. however i do these all day without taking the intake manifold off and find it funny that every video recommends you do take it off, also 1 plug and 2 clips takes the fan housing off and gives you lots of extra arm room

[@squealer80]

This is the way

[@toastybuns5281]

Got the pump replaced on my Mk3 TTS recently. I’d done DIY work on my Mk6 GTI, but honestly having watched this I’m so glad I had a shop do it instead 😅 hopefully I’m good for another 60k

[@ToadxGaming]

How much did you pay?

[@toastybuns5281]

@@ToadxGaming $1250

[@davidthegoliath1]

You can actually sneak this out by taking out the boost pipe on the right side and not going near the intake manifold. Everyone to their own though but saves a ton of hassle. Just have be careful of the plastic union when going back in.

[@red95gts]

Very nicely done! My water pump isn’t leaking now but I feel much better prepared to tackle it when it starts. Thank you!

[@phendrix9476]

Great video with excellent narrative and shot angles. After seeing this, I appreciate my Toyota/Lexus vehicles so much more. After driving a Golf R, I still may take the leap. Bwahaha

This video was very helpful!... helped me to realize that I am not gonna do it. Im going straight to the shop.

[@Eudorus314]

I'll be following your vid later this week when I replace mine. The dealership wanted $3K to replace the water pump alone...

[@MarioPalomarez-k1l]

The dealer said the same thing to me. How can they justify this cost!!

[@jameshaulenbeek5931]

$3k? I was quoted $1400-1500 *IF* it wasn't covered under warranty. I decided to do it myself - learning experience, and the intake ports were crusty.

[@NotFriendsGaming]

I was just thinking dammit how am I gonna do this on my 2020 Tiguan you are definitely the man Charles!!!

[@tommythiffault6839]

I always replace these without removing the intake, it’s also a good idea to inspect the balancer shaft seals if it’s leaking it’s so much easier to replace when the thermostat is off

[@goldfishman2]

how would you replace the balance shaft seal? my understanding is it runs through to the front of the engine and it is part of the timing chain.

[@aygwm]

What an insane amount of work to do a water pump. I guess it isn't as bad as doing a whole timing belt job but this was so much easier in the mk1/2/3 cars...

[@stevegee218]

An optional tool for the hard fuel line is a Lisle 12720 Line Socket, 17mm (Or similar injector socket) . This makes taking off the fuel rail side much more easy and lets you use the torque setting. They are 3/8 drive so still compact.

[@Malc2169]

Thanks Charles for a timely instructional video! I’ve got to tackle this on my wife’s 2018 Golf. How long would you estimate an enthusiast mechanic would take to complete this?

[@TheCarGuru]

Amazing job, Charles! Your videos are always a wealth of information/inspiration.

[@JordieG8]

I just noticed my 18 S3 has a minor water pump leak. Great timing Charles. lol

[@jim78]

great video. i usually do this with out taking manifold off. once you do a couple i feel like its easier to just leave it

[@brianlachapelle8757]

FYI: I didn't have to undo the 17mm nuts on the fuel line. Just take off the clamp on the fuel line that screws into the intake. Great tutorial though, Charles makes it look so easy@😊

Its a tricky job, a lot of frustration during disassembly but it went together much easier. Ridiculous design that you have to take the pulley off to replace the belt, and how do you torque the next bolt? Not enough space for a torque wrench

[@richardhunt1384]

Done a few pf these and struggled to that poxy cotton reel to stay in place whilst fitting the pump. Once I've got it in place and bolted up I then panic hoping the reel hasn't flipped out of alignment or something then have to double check it's all in place. Also never thought of putting the belt on whilst fitting the pump, that's a good tip, like that. 👍👍🙂🙂

Anyone looking to go into the auto trade, should look at getting trained on one Make of car and make sure your at the top of your game. When you open your own shop you'll be at an advantage over other shops who don't have your specialist knowledge, specific tools and you can buy parts in bulk.

[@jakedalton3352]

I’ve done a lot of these you can get away with not removing the manifold it’s a bit more fiddly but worth it

Impeccable timing as my water pump just died yesterday.

[@KevinHahn-o2z]

So, I recently had to replace the water pump and thermostat housing on my 2016 Sportwagen with the 1.8T and this video was extremley helpful. While I had the intake out, I decided to clean my valves. Cleaning went as expected and all went back together as it should. Only problem, now the car won't start. It cranks fine and is not throwing any codes to speak of. I feel like there is a sensor disconnected somewhere or an underlying issue with the intake runner. Any thoughts on what would cause a crank no start after doing the water pump and valve cleaning? Is there a reset I should perform? It did sit for several weeks until I had time to get it all taken apart and put back together.

[@Werewolfmage]

lol you make it looks sooo easy :) i had to do one on a tiguan my boss had me do it to save the customer money on parts with the manifold on. was NOT a fun time. next time i yank the intake

[@MegaHollywood1971]

If you conduct coolant fluid changes more frequently, you will not have the issues depicted here. The coolant that was in this car was old and thus, had no more lubrication to provide and/or it was mixed and became more corrosive. Keep it fresh and over time you won't see this. Thumbs up Charles...

[@StealthGTI]

I think my oil cooler is leaking. I saw its location for the first time in this video. So, at least now I know where to look for external signs of leaks, if one exists. Am I interpreting your actions correctly by thinking that the water pump has to come off to replace the oil cooler gasket? Or can this be done without removing the water pump and everything else shown in this video? Thanks!

[@lucasportinari4975]

I just want to say thank you for doing this video I have a 2020 Audi Q3 and I have 80,000 mi and I was going to do the water pump but I'd rather pay somebody to do it cuz it's a look like a disaste.

[@ericjudd1415]

New video Sunday! Yay! Ever thought about doing a shop chemical video?

[@lobster8009]

Interresting. I actually do have a very slow water leak at my pump on an 2017 Polo Gti DAJA engine. When i say slow it drops from the max to the min line on the bottle in about one year. The shop that found the leak by pressurizing the sytem they of course told me they wouldnt want me to leave without fixing it and it would cost about 2000€. I kindly declined and here we are 3 years later. Its not given me any bother since then, i just checked the fluid every now and then and refilled as needed. But i do understand it could blow any second and cause a major bill when the engine overheats. Doing this repair myself sadly seems a bit above my head tho.

[@Branch846]

Going to be doing this really soon on my golf, great video. Just wondered about the 12mm for the belt, did you manage to do it with a spanner or did you have to special tool? Thanks

without reseting the coolent acutaor, i notice on my 2016 Q3 the fan kicks in often during the summer. I'm going to try resetting it and see if it helps that issue. btw, it didn't do that when i first got the car new. only after the dealership did my maintenance over the first 40k miles did i now notice it since.

[@jonnyvt6602]

When I had the pump etc replaced on my Leon Cupra at 75k, I asked if they could check my intake valves for carbon; they said they do the fitment 'blind', without taking of the inlet manifold!!

I've got a question, I replaced my waterpump but when I start the car it goes into limp mode and heat gauge goes right up without the car heating up, I plugged in a machine and it states the actuator .. Any help would be appreciated 🙏

[@TheUberdude14]

Hi charles, ever seen the balance shafts go bad on these engines? we had a customer in with a 1.8tsi engine that was running hot, diagd a leaky thermostat/waterpump and no coolant in the tank. when mounting the new pump we allways turn the crank so we can walk on the little "timing"belt and to my suprise the little pulley on the end of the balance shaft wasnt turning with the crank. Ive checked if the counter clockwise bolt was tight and it was. gonna pull the lower timing cover on monday to see if the balance shaft chain broke

[@timbo7457]

FYI I had the warrenty done on mine...didnt make it 2 years. Honestly if you have to do this get the aftermarket aluminum one, well worth the investment, I got lucky and found a mechanic that said he would order the aluminum one because the stock one is known for failure.

[@bloodhoundsoldier7445]

yeah need this rn sadly, haven't checked to see if it is the water pump yet but i'm starting to believe so because i've lost a little coolant and i'm hearing a ticking noise from the engine
