Thanks again guys, Just went to change the oil in my chain drive, removed the magnetic plug just rear of the right front drive axle and a ton of fluid started spilling out. I think it was transmission fluid! I put it back in fast! As I understood it this plug is a fill to port like that of a differe...

Haven't been here in a while. Everyone told me head gasket. I had 2 coolers fail. Long story short I ended up bypassing it just for peace of mind. No more coolant in the oil! The other place I thought coolant might get into the engine is the tube for the crank case ventilation. coolant and vacuum li...

I think the T6 was the one with all the Trans issues.

Mine went out at 75,000 mi. Really poor design. You would think for a car Volvo was going to build for 11 years they could have designed a trans to fit, instead of using a GM trans.

Thanks in advance for any input. Car use to get 18 MPG per the computer. Dropped to 14.5 recently so I changed the O2 sensors. This had no effect on the MPG. Next I cleaned the mass air sensor with CRC MAS cleaner. That screwed up the sensor, so I replaced it. Now the car is getting 10 MPG! Where to...

The problem has returned with the cold weather. Coolant in the oil once again. I cant believe the oil cooler could go bad in less than 10000 mi. I love my Volvo, I love my Volvo, I love my Volvo, I love my Volvo. Anyone have a match?

I had a similar problem after hitting a big pot hole. The car pulled hard left during braking. One mech. missed it another found lower cotrol arm bushings broken.

Have the oil tested for coolant (NAPA has a kit you send away to a lab). Mine had the same problem and it was the oil pan mounted oil cooler. I replaced it and the coolant stopped dissapearing. Make sure you change your oil to get fresh oil in there if you find antifreeze in there.

New oil cooler has fixed the problem! No more dissapearing coolant.

The oil cooler is not integral with the radiator but it has coolant running through it. It's not a air to oil cooler, it's a antifreeze to oil cooler. Coolant is pipped to a manifold at the back of the engine that supplys the oil cooler and the turbos.

It's a T6 AWD, the cooler mounts on the back of the oil pan and has coolant lines running to it.

No I dont do any towing (I want the trans to last longer).
