#1139 of 1197 Fan problem with AC & Heater
Apr 21, 2009 (11:24 am)
I have a 98 Volvo S70 and have had some problems with the climate control system. I just had the AC recharged and the system will give both heat and cold, but the fan is temperamental. At times it runs perfectly and the speed responds as I change the dial. Other times I can have the heat/AC on full blast, yet the fan does not blow at all. At those times, I can feel the heat/cold lightly wafting from the vent so I know the temperature is responding, but the fan does not blow the air. The other day I was driving with the AC running perfectly, but the speed of the fan seemed to be affected to my driving speed---if I sped up quickly, the fan would slow down, and when I slowed down the fan sped up.
#1140 of 1197 G70 GLT 1998 coolant low, now i'm overheating!
Jun 04, 2009 (5:13 pm)
before relocating from southern california several weeks ago i noticed my engine coolant light began flashing particularly when going up incline. had a local garage mechanic check it out. they replaced the plastic reservoir tub ($50) that holds fluid. Mechanic said there was a hairline crack at the base. Three weeks later same thing happened with coolant light and the reservoir was low again. Took car to West coast Volvo dealership who said I needed new radiator- huge cost, several hundred plus several hundred labor. A month later same issue so i filled it with water and had vehicle shipped to east coast. Once car arrived brought vehicle to local east coast Volvo dealer who checked system (pressurized it I think ) and said it was fine and then topped it off, but said there was a leak with the O cylinder near the transmission, and replaced this- another several hundred dollar cost. It was fine for another two weeks and then the light came on again, and sure enough reservoir was only 1/4 full.
Does anyone know what the problem might be? Is there some sort of air pocket that won't allow the system to fill properly? Or is there some sort of affiliated turbo issue or transmission issue that is using large amounts of coolant?

If you overheated the engine, you could have warped the head. This would allow coolant into the cylinders. Happened to my ex's Mercedes. We had to re-do the head on it.

Thanks for your thoughts. I sort of doubt that I overheated engine since I did little driving in LA in the past year I was there and usually stayed on secondary roads, no high speed or long distant driving. I never saw any overheating indicators. Wouldn't professionla mechanics be able to identify this if this were the case? I've had two different volvo dealerships look at this issue to date. How does one check for this condition?

Doesn't take much to overheat an aluminum block engine.
IIRC, if you see a lot of white smoke coming out the tailpipe you are burning coolant.

The title of your post stated you are overheating. Then you state you never saw any overheating indicators. Which is the truth?
As Vmax stated, overheating on an aluminum engine is a very very bad thing.
How many miles on the vehicle? It does sound like you may be burning off coolant; however, it sounds like it is slow enough that maybe it wouldn't be noticeable at the tailpipe.

ours has 65k miles on it. $3k repairs in last year, $5k in last 2 years. they want to do $1.5k more.

That's what you get for going to THEM and letting THEM decide. THEY will always get you!
#1147 of 1197 Should I run not walk away from a used 1998 S70?
Jul 29, 2009 (8:57 am)
I have an appointment to look at a used 1998 S70 today. Car looks amazing. It does have 114K miles on it but considering the price that is really nothing. Owner says it is in great running condition but that the check engine light is on for the O2 sensor. I had the same problem in my 2007 Yukon so that doesn't steer me away. Reading pages of complaints however does. I know all experiences are different and all makes of cars have problems. Heck my 2007 Yukon had a new transmission at 36K miles so it does happen.

The S70 is a great car. But I'd like to see all service records if buying one with so many miles. Timing belt is of utmost importance. It is due every 75k that year, IIRC. Also want to know if the transmission was ever serviced. Fluid should be changed regularly (I suggest every 30k).
