Question about 1990 Buick Century
My 1994 Century Buicks heater just blow COLD air, I flushed the system, changed the theromstat, went through all the hoses & radiator(all clear) and I still get NO hot air from the heater. Now the temperature gauge goes up and down, if I'm going slow, temp rises past normal range, then back down when I speed up. When just idleing it seems to run in the normal range, with or without the radiator cap on. HELP or I will shot it!! Thank you.
It sound like you have a block or plug up heater.If you just used a garden hose that is not a flush .A reel flush is called a power flush it used about 150lb. of air&water mix. Find a Radiator shop to do this. as far as your temp. going up and down you may have an air trap in eng,an radiator run car for 20min without the cap on. I have been doing Radiator work over 34 years

Did you make sure you got it full of coolent? i am saying this because if you don't it will create an air pocket in the system and it will not throw any heat until you get the air out. on some models there are relief valves either on the thermostate housing or buy the water pump to do this. all that needs to be done is to start car and let it run a few minutes to get warm and open the valve and let the air excape whenyou see a steady flow of coolent close valve and you should have it.
