hi all,
1997, Lumina LS 3.1/212,500miles
today morning, it will a bit cold, so i have turned the heater on for about 10 minutes then turn it off.
in the afternoon, i drove my car with a/c on, and noticed a very high coolant temperature...and raising. the needle was in a very visible motion of increasing and sometime decreasing with the same speed.
even on idle the temperature is very high...even the fan are not doing any good to the temperature either.
now, when i came back home, i have open the hood and found out that there was no coolant in the coolant reserhevoir....again i have filled it up with some water and turned the car on....still temp was high...then (just to check) i have opened the two bleed screws and found that only air is coming out of them with a lot of pressure - from both of them.
now, i got no idea what happened to my car...i have only turned the heater on in the morning...and thats it.
i have never faced any overheating problem before and all just worked fine till today morning.
Please help me to find the problem.
Thanks and Best Regards
