Why would a 1989 Chevy Silverado 350 heater only put out luke warm air even after changing the thermostat and back flushing the heater core?
I had the same problem. The answer to your problem is simple. You have an air pocket in your cooling system. Simple fix - take the radiator cap off of the radiator, turn the vehicle on and let it run for 1hr to remove the air from the system. Also, make sure your overflow container is atleast at the minimum level. Answer If your certain you have all of the air out of the cooling system the blend door inside the heater box may be stuck open.
Heater problems 2000 GMC sonoma 4.3 vortec?
If all the inside controls are working and you have antifreeze in the cooling system them I would suggest that you check and make sure that the thermostat is working and after that check to see if the heater core is stopped up. If so then you will need to completely flush out the cooling system including the radiator, block, all hoses and the heater core.........

What type radiator fluid is used in a 1993 Pontiac Bonneville?
You have a 95 grand am would the heating core cause the car to overheat and lead coolant what is a heating core?
Yes, the heater core would cause a vehicle to overheat. Most likely it would either be caused by a blockage, or some form of interruption of flow of the cooling system in the area of the heater core. It is an integral part of the cooling system, much the same as a part of the body being included in the circulatory system. The heater core is basically a small radiator that is located behind the firewall. It is encased in a small insulated box, and its main function is to allow the heat that is generated from the cooling system to be pushed into the passenger cabin by means of an electric fan that is usually attached on or near the heater core. It also aids slightly in the cooling of the engine when working properly... but when clogged or working improperly, it will not allow the regular flow of coolant to continue, therefore causing the engine to overheat. I hope this answers your question.
Asked in Dodge Ram Van
What would be leaking from the cooling system under the dashboard passenger side on a 1999 Dodge Ram Van?
Your Heater Core Sounds Like. heater core Another answer== Water from condensation when using the AC, or coolant from the engine cooling system. Test to tell: if it smells like antifreeze, the heater core is leaking. No smell or just smells wet, it it condensate and a drain line is plugged or blocked causing the water to back up into the passenger compartment.
Asked in Cars & Vehicles, Mitsubishi Galant
Your 2003 Galant will blow air but no heat why?
I would suspect that the heater core is either clogged or the heater temperature control valve is defective. Have you ever serviced the cooling system? It is also possible that the thermostat is stuck open. I would drain and flush the cooling system. Install a new thermostat, install a fresh 50/50 mix of the correct antifreeze and distilled water. See what you have before proceeding any farther.

What would cause the heat in a 1991 Buick Skylark not to get warm?
Thermostat possibly stuck open. Another possibility is the heater core is clogged. I would recommend you perform a complete cooling system service. Drain and flush the system with the heater set to high. Replace the thermostat, and install a 50/50 mix of coolant and distilled water. Bleed all air from the system.

Asked in Plumbing
Do you need to drain all the water out when flushing an electric hot water heater?
Your temperature gauge indicates overheating but water and oil levels are fine and heater works what is wrong?
If you are absolutely sure you do not have air trapped in your cooling system then you may have a defective gauge if you are getting heat through your heater. Usually I would say you have a coolant flow problem with either a stuck thermostat or a bad water pump but if you have heat from your heater, then you must have circulating coolant in your system. I would check the gauge or the sensor.
