I am installing a good used replacement recirc air damper motor (Volvo #6849557).

I connected/ installed motor and observed the actuation rotation (angle) exceeds the damper arm's travel, causing noticeable motor to bog under this stress.

I carefully opened the motor ...

I see the torx screw. I can take that one out. I am talking about removing and replacing the plastic coupler on the firewall, where the 2 silver pipes go in. Once those 2 silver pipes are detached from the heater core end and the gas pedal removed, can the black coupler plastic piece slide over to ...

Once gas pedal is removed, can you shift the heater hose coupler/attached heater hose tubes to the left in order to clear the evaporator casing?

Hi John & others,

I finally got to the root cause of my moisture in tailpipe problem. I went to local auto parts store and bought a $30 hydrocarbon test kit. It confirmed I had exhaust in my coolant. I pulled the head off and checked for warp , using a decent carpenter's level (milled prety flat ...

I have exactly the same repair issue. I need to change out the heater coupler on my '96 850T. However my heater core connects to solid metal pipes from heater core to coupler, not flexible tubes. Does someone out there have a procedure for methodically removing the necessary console/dash items to ...

Thanks for the replies, guys. I will try the 100psi test. You said to do the 100psi test at TDC. Wouldn't it be better to find a block crack by doing it with piston all the way down the cylinder bore?

BTW, I talked to engine guy and he's is willing to swap me another engine. Seems like the right ...

Bought a used engine w/94K miles to replace overheated (warped) head on a resurrected 96 850 Turbo. I also replaced the radiator. After 10 min of idling, condensation comes out exhaust. Feels wet like steam. Engine runs strong, turbo smooth and quiet. After 25-30 min of driving, engine "recorrects ...

What exactly do you look for in compression readings to rule out a head gasket? I have a 96 850 turbo that lets steam out exhaust after driving 15 in, but conpression is even and 175-180 across all 5 cylinders.

When using K&N filters, put the oil on sparingly. I've heard of MAF sensor problems due to overapplication of the K&N oil. Less is more.
