Bad Coolant leak

Just curious if anyone’s encountered this for a 95 Volvo 850 r.

I lose all my coolant like in 30 minutes of semi hard driving.

I’ve checked almost everything Ik of and can’t find where it’s going

Weird misfire issue after head gasket job

Hello people of the volvo 850 forum, i recently replaced the head gasket on my 96 850R the job went well with all cylinders at 125-130 psi in a compression test, but im having an issue where the car is misfiring at high boost (see video) and at idle under load when stopped in drive or reverse. The middling range of rpm and boost is smooth, the misfires aren't constant.

For some context before i replaced the head gasket i was having an issue where the peak boost wasn't being reached but the car wasn't misfiring. I had driven the car like this for quite a while.

The current car's equipment goes as follows. I'm using a kinugawa wastegate actuator with the 14.7 psi spring and the IPD heavy duty bypass valve with the 15-16 psi spring. Everything else in the car is stock.

I have a theory about what it could be. I was thinking that it could be the ECU learning how to correct the air fuel mixture now that it can reach full boost. However ive driven the car for over 1200 miles and the issue hasn't gone away however i havent driven it in the range of rpm and boost that had the misfiring issue.

Idk what it could be id love some help.

My serpentine belt is slipping off the alternator because of the tensioner (I just replaced the alternator) do I have to replace the tensioner or is there a way I can rig it?

Volvo 850 hidden intake manifold bolt

I’m working on the pcv for a 94 Volvo non-turbo 850. There is a bolt behind the therm house that I have not been able to reach or get to no matter how many u joints and extensions I’ve tried

Random shot but does anyone out there know what I’m talking about and could give any guidance ?

I was able to get everything off but putting it all back has been more frustrating than removing 😭

Advice needed: Valve cover sealant replacement

Hi guys,

I have a large oil leak on my volvo v70r from 1997. My mechanic told me that the Valve cover sealant needs replacement and wants to charge me 5 hours. Is it really that complicated? Do you guys have a experience on that?

Thanks in advance,

Philip

YLOBRIK - gorgeous 850. Shame it’s not the long roof. But a beauty.

Strange noise from rear suspension/hubs

I've got a weird one.

When the steering lock is anywhere to the right of centre the weird noise in the video turns up.

I can't tell if it's coming from the left or right hand side.

Any ideas? I had a look on here first and I seem to be the first person to have this problem!

Aluminium Control Arms!!

I got myself a pair of aluminium control arms for ~35€/piece. I used the polishing tumbler at work to clean the control arms, replaced the bushings and the ball joint. An absolute steal considering how rare they are (last pic is before and after)

Wondering if it's worth the work to replace my own pwr steering rack

Got a 98' base v70 that blew a main seal. Ordered a new rack from Detroit axel and intended to do the work but I probably have to spend like 200 more dollars on tools and some other replacement parts.

Would anyone know a ballpark estimate of a rack replacement from experience?

850/V70 amp issues

I recently decided to buy an OEM 4x50 amp for my SC-805 radio, only issue is the amp seams to not work at all, I’ve ruled out any issues that isn’t the amp. (cables, radio, speakers) Nothing inside the amp seams to get warm at all. (The circuit board doesn’t want to budge out the housing, but it looks to have several of those tiny resistors on the underside.)

Will S70 coilovers work for a 97 850 glt sedan?

I have a 97 850 that I've been struggling to find coilovers for and was wondering if I'd be able to use some that are compatible with a 98 s70
