AC & COOLANT QUESTION S70 1999

posted by  someone claiming to be joesbelmont on  Mon May 24 17:08 CST 2004 [RELATED]

My air conditioning is blowing hot air. The compressor is working, but it is cycling on and off every few seconds. The fan is blowing fine. No lights are blinking on the climate control unit. Right now I am using a 4 window air conditioning system, it seems to work better. I tried the ac again a couple of days ago, and a puff of white smoke or dust came through the vents into the cabin. What could this be, or do I just need to throw some freon at the problem?

I also have a coolant leak somewhere. I have been topping it off regularly with volvo coolant and water. It has gotten worse though. I only took 5 days to go from the max to min level. Is there something that I could pour in to help fix the problem? And could this be related to the air conditioning?

Thank you,
Joesbelmont

    greetings,
    sounds like the ac has leak in it, can top up with a can of r134 and possibly have it diagnosed by ac shop, if its evaporator leak its big bucks, or you can try sealer available in auto zone costs about $20.00
    good luck

    Sounds like time to add a can of r134a. Meanwhile, don't open both back windows unless you have nothing of value in the car. That acts like a vacuum cleaner for the back seat. Open the LF and RR windows for maximum effect.

    As for coolant leak, could be head gasket, radiator leak, etc. Have the system pressure tested.

      You could possibly have a bad water pump.

      Also, the best way to tell abou the a/c is to have a dye test done to check where all the leaks are. The mechanics use a dye in the a/c system that they can check the leaks using an ultraviolet light.
