Thanks Robert. You are a great person and excellent tool to help us with our Volvo’s.

[@RobertDIY]

Glad to help

[@dudekoda]

You are awesome! I'm still having issues with my 98 v70, but with your videos I'm slowly getting her back into shape

[@RobertDIY]

Good deal.

[@donblankenship8445]

Thanks Robert! Great video, working on a customers car had many vacuum lines completely missing. This was very very helpful. Thanks again, keep up the good work.

[@RobertDIY]

Glad it helped. Thanks for watching.

[@nwsights6301]

Thank you so much as always Robert, just about every video I've looked up to fix my 98 NA V70 has been your videos and they have saved my butt! Please keep up the videos.

[@RobertDIY]

Thank you for watching.

[@houseofbrokendobbsthings5537]

Thanks Robert - very handy. I did the trip computer change from a 94 850 to a 97 850. Worked like a charm as you stated. Just changed my odometer and the odometer motor as I used the 94 instrument panel to get the cool boost gauge. Thanks for all you do!

[@RobertDIY]

You are welcome

[@ViktorNova]

THANK YOU, I seriously had no hope of ever understanding what I'm looking at with this crazy system before watching this video. You basically are the reason my 98 V70 turbo (just under 200k) has still been going after all these years, hoping to conquer these vacuum issues and get it back on the road

[@RobertDIY]

After watching many of your videos Robert, I'm convinced that you are a Volvo wizard. I also know that unless you somehow became my next door neighbor, I will never buy a Volvo. Holy crap they are maintenance intensive! Lovely cars but too finicky for me though. Great vids though and I am learning a great deal. I will continue to follow your channel for sure.

[@RobertDIY]

+Merlyn Sk Thanks for watching.

This guy rules. I've had the C70 and now own an S70. Good engine if maintained regularly. I prefer the hpt engine over the low pressure system I have in the S.

Great video robert. The vacuum lines should be the same for any 1998 turbo variant S/V70 GLT/T5. Also the plastic hose you mentioned that goes from the air intake tube into the metal line behind the engine routes to the Fuel Pressure Regulator near the front passenger wheelwell.

[@RobertDIY]

This was so helpful! I now know that I put my boost gauge on the wrong line. I put it in that purple line. That's wrong I'm now thinking. So what line do I hook my boss t gauge too? Thanks ahead of time

@@RobertDIY oh wow I'm sorry sir.. I have a 98 Volvo s70 glt. Pretty sure the timing belt hasn't been changed in 230k from what the last markings say on the ecu cover.. I'm almost 100% positive the pcv system is totally clogged it's got 302xxx miles on it. And the previous family let's just say didn't know anything about anything so like nothing got done to it.. And I'm trying to save it lol thank you

[@NightShiftGarage_PT]

Hi Robert. It's very different 1998 and 1999 engine. For example, this is exactly as my S70 1997, but not for V70XC 1999.

[@RobertDIY]

Not VERY different. They both have turbo's, TCV, etc. But if you'd like, you can video your issues and post for suggestions.

[@victorsinclair1115]

Thanks for the explanation of the spaghetti mess of vacuum hoses that is our Volvos. Is it common for the brake master cylinder hose under the battery to leak? I seem to have to push way to hard on my brake pedal and can never push hard enough to lock the brakes. (ABS light on so I should be able to lock my brakes)

[@RobertDIY]

+VictorSinclair No, but you may want to replace it. - kzbin.info/www/bejne/Zqu5aaF9mqyoobM

Hey Robert , how you doing? ive been watching your videos for months they're great thanks so much for posting them they have saved me scratching my head heaps :o) , im currently doing a head gasket and head swap on my 98' GLT V70 i should have it finished in a day or 2 ,torquing down the Cyl. Head was a tedious job especially the last pass of 130 degrees , this video on vacuum hoses will help me out greatly tomorrow thanks again, i have a question its a little off topic , if you were to run NA cams on a GLT would there need to be any ECU tuning done? from all the videos ive watched that doesn't get a mention at all . the only thing ive learnt is that the max torque and power moves up the rev range a little i believe , your advice and info will be greatly appreciated. cheers from downunder Carlo B

[@RobertDIY]

DO NOT INSTALL NA cams on a GLT vehicle.

is it safe to assume that all volvos, in particular my 97 awd have the same vacuum tree in the same place? wanted to put in a boost guage and was wondering where my vacuume tree was.

[@gashiflett1]

Robert, I have a 98 S70, and it appears to have a electrical wire connection under the brake fluid container, that is not hooked up. Is it possible a wire is there that may be for something do not have on my car, since I can not find connection for it.

[@RobertDIY]

+Glen Shiflett probably not. Volvo usually has termination plugs for stuff like that.

Thanks Robert, It looks like I need to do a bit of research to determine where the wire is connected

I think 4mm.

[@travisgarrett2439]

hey Robert, the hose at about 3:55. the rubber boot on one end broke, and I cannot find the nipple for the life of me. it's still attached to my air intake, I just can't find the other end, and it's kind of hard to see in this video. any advice? you the man.

It rides on top of the lower radiator hose pipe.

[@jamesbardes2487]

@@RobertDIY I'm having the same problem finding this one as well. I tried looking underneath the two rows of vacuum and pcv tubes and i can't find the nipple or the broken end. Any advice on where to feel, or is it easier to find it from underneath? It's the last line i need to replace and I'm stumped. Thanks for all the videos, they have really helped bring a 98 s70 to running fantastically!

[@leomtz4re]

Robert, Great Volvo repair vids. Used almost all of them after burning a valve in our 98 S70 turbo. A starting issue though after getting everything assembled: engine turns over but doesn't start (sounds like it wants to, but stumbles then nothing), I have a spark, fuel, timing marks look aligned and changed the cam position sensor. Also the battery is fully charged and new spark plugs. Are there any hoses that would cause a 'non-start'? Any other ideas on where to go from here? Thanks in advance.

[@RobertDIY]

Turbo piping will cause it not to run.

[@RobertDIY]

kzbin.info/www/bejne/j5qzcoOrYrBrhas

[@leomtz4re]

Ok. I'll check the Turbo connections, appreciate the info. Love your informative DYI videos.

[@leomtz4re]

Found a couple of hoses not connected fully, fixed them but car still doesn't start, turns over but doesn't start. 2 questions:1) does the slots on the back of the cams follow the same rule as the 850 model you've demo on in another video? I suspect that the timing marks are incorrect ( I didn't mark the cams when I removed them). 2) If the cam postion and crankshaft sensors are defective is a spark still present in plugs? Thanks again for your help, Leo

[@RobertDIY]

If timing is off or cam sensor is bad it will NOT have spark.

[@TechBurnoutelite]

Hello. My friend of my has a volvo 850 t5 that has some idle issue. It sometimes has perfect idle. But sometimes is goes up and down and dies and blacksmoke on throttle. We changed temp sensor,lmm,lambda/o2sensor. And throttle posision sensor. We also checked vacuum leakes with either spray and it does not seems to change idle. I has a air noise where the turbo is like a blow noice. We cant find anybad vacuum hose either. Do you have any experience of this! Thanks alot! :D

[@RobertDIY]

+TechBurnout Codes?

[@TechBurnoutelite]

It has no codes. But the engine light is still on. I sometimes get lmm and temp sensor codes and memory loss in computer.

[@RobertDIY]

That's strange. How do you know the computer suffers memory loss? It may have wire harness issues.

[@TechBurnoutelite]

Its factory. I dont think it has that issue. Even if you drive it gets that whay. But often when it warms it seems to work like normal more. But not at all when its cold.

[@jeffreylyles2649]

What's the part thats attached to the bottom of the battery tray?

What size are most of the hoses??

[@oliverjafs]

I'm just wondering if this could cause the car not to build up enough vacuum to start the car on the first try but enough to start it on the second try? And also mine has been drinking more fuel as of lately, wondering if this could have part in that too. Appreciate any answer! Thanks.

[@RobertDIY]

Why would that happen all of the sudden? Did you pull vacuum lines for no reason? Probably have a bad fuel pump.

[@oliverjafs]

@@RobertDIY I went up a big steep hill while camping, troubles started coming after that. But I'll check the pump!

The hose that is connected to the intake goes to youre fuelvalve

interesting.

@@RobertDIY mine was broken off so it was running way to rich because the valve didn't have vacuum. If you look under the car you see a small little pipe together with a cooling hose, if you follow that you will see the valve👍🏼

Flutter?

You would want to remove the bypass line and vent to air for your “flutter”/turbo sound when you let off the gas. Not sure the result on this car, but most it will run worse and throw a code. Price you pay it you want to sound “cool”. Goodluck.
