Poor output from the heater and/or engine overheating can be caused by air left in the cooling system after the cooling system has been serviced. Our technicians tell us the proper coolant fill procedure should be used to prevent this problem from occurring.

water pump was changed by myself a lot of work to do new thermostat and new oil pump also. now we have no warm heat in the car I opened the air bleeds no air coming out of air bleeds heater pipes are hot still no hot heat firstname.lastname@example.org
The heater doesn't blow warm air properly when the heater was on. It has been going on for several weeks before the temperature gage shows overheating. When checking the reservoir, the coolant was very low. However, I could not find any leak by visual inspection. I put coolant to the max mark. The car seems to run fine now. I am not sure if there is a leak anywhere that I cannot see.
.I had some problems with overheating and took the car in for repair during the summer. Now I have a problem with very little heat from the heater, does that sound familiar ?
Head gasket leak, bleed coolant to release air bubbles
Car keep overheating
I just had the radiator repaired about 8 months ago. I thought everything was okay until yesterday I noticed the temperature gauge needle climbing up rapidly to over half after less than a mile. I also noticed a strange smell whyich makes me think that maybe I need to have coolant added. Only I do not know what part of the engine to add.
After many hours of testing the cooling system, I tested the heater core for blockage internally, and found the heater core to be almost plugged up. I replaced the heater core and it solved the problem! The heater core was under $100.00, but it took me 15 hours to complete the repair, and I am an SAE certified "Master" mechanic. If you have a repair shop or dealer do the work, it will be expensive.
