So quick and "dirty" update: Coolant is still leaking and it seems to have all gone to my engine oil side. Noticed significant amounts of white smoke (water vapor) coming from the exhaust one morning about three days ago. Checked the coolant level and it was gone from the reservoir. Checke...

Yes the coolant reservoir was pretty gunked up after the oil cooler went bad. I wanted to replace it back then, but listened to that old mechanic who cleaned it out during the flush. Will look to replace in the near future anyway. Transmission fluid, engine oil, have been replaced. Next thing is new...

Got the car back this week. Turns out it was just "missing" 3.5 liters (~1 gallon) of coolant. Mechanic didn't find a leak and it so far has been working just fine (heat, no fan, engine temp) once we filled it up. Makes me wonder if the first mechanic didn't let the coolant run through all...

So now I feel a bit sheepish...... I took a look under the hood after driving and spinning up the fan to see what I could find. Turns out that there was nothing in my coolant overflow tank. That would be an explanation to why the fan turns on immediately when driving and is so loud since it's workin...

Having just looked at what a heater core actually does, I wonder if the issue with oil getting into the coolant (recently fixed with the new oil cooler) clogged it up enough to result in loss of heating to the cabin. The mechanic said they had to do multiple coolant flushes to clear the system. Sinc...

When I mentioned the issue to the new mechanic his first thought was thermostat as well (+1 for him vs the old one). When I had the new oil cooler put in I specifically asked them to get the Volvo coolant, having read it might make a difference. What I noticed too was that they were using a differen...

Yeah, my wife bought the car before I got to take a look at it or drive it. She already feels bad enough, so I don't want to make her feel even worse but we are getting close to reaching the line. The car already had the transmission replaced according to the previous owner. It's just outside the ye...

The fans comes on after about 3-5 minutes of driving. The car doesn't overheat, stays normally at the half mark, but I noticed that if idling at a light it can go up to 3/4 on the temp gauge. Then it returns to 1/2. I'm a bit stuck in that I paid probably too much for it (without knowing all the iss...

I bought a 2006 XC90 T6 (European version) this summer and seem to have problem after problem. Currently the radiator fan runs so loud like it thinks it's an airplane and is trying to take-off. It does this while I drive and for a few minutes after I shut off the car. It's cold where I am (between 3...
