Another quick question about a part for you guys. While trying to chase down my problem of my car not starting I noticed something else that caught my eye. It appears to be some sort of actuator that is located right next to the transmission fluid dipstick. I noticed a dark red powder around it and pulled it off to discover that it's rusted shut and is extremely difficult to open and shut by hand (lots of rust grit in there). It's hooked up to a coolant line, anybody know what this is called and where I can buy a new one?
Thanks so much guys, and by the way, I haven't found my main problem of the car not starting yet. Hopefully with the tips I've gotten it'll be soon though!
I believe you are looking at the temperature control valve for the heater. It should have a vacuum line attached to it and it is located in one of the heater lines. The other heater line runs right up to the heater core next to it.
These can be purchased from one of our GN vendors or a parts store. The parts store may not have the "stock" type which is a ball valve type valve.
Sounds like you need to empty flush and refill your coolant system. Use distilled water and RMI-25. What do the tubes of your radiator look like? When the engine is cool, remove the cap and look down there, if you can't see drain some coolant out by loosening the petcock and have a look.
It is the heater water valve. It stops coolant flow to the heater core during A/C operation. When no vacuum is applied it is the open position. Vacuum closes the valve. Do not use a plastic valve. The correct valve is GM # 25523118 and is a metal valve.
Hey guys, thanks so much for the tips on this one. Now if I could only track down my electrical demon. Hopefully I'll have better news tomorrow.
