The thermostat is located on the top hose coming off the radiator. It's a 2-3 inch diameter hose, there should be two coming off the engine block into the radiator. If you look, it's almost always the top hose. You can see two or three bolts and a clamp around the hose going into the top of the thermostat. A new thermostat is around $30 - $60 depending on the car. You will need two quarts of antifreeze and I also suggest getting 'indian head' gaset sealer, put this only on the engine block side of the thermostat. Let me know how it works out and if you need more help.

How do I fix the heat


You have one of two problems. The heater core is plugged /
restricted or there is an inoperative internal blend door motor problem. Start the vehicle and let it reach operating temperature. Feel the hoses under the hood that go into the heater core. They should be close to the same temperature. If one is hot and the other luke warm/cold.... the heater core is plugged/restricted. If both hoses are near the same temperature, suspect a defective/non operational blend door motor that controls heat/cold/airflow attached to the heater box assembly

Only get defroster. won't change to other levels.


That heater control is powered by vacuum. There is a small hard plastic vacuum hose going through the firewall next to the brake booster. This plastic line feeds the control panel and is either cracked or disconnected from the control panel. If your heat is only warm, then your thermostat is probably bad.

My heater is blowing cold air ,i changed thermostat and heater core ,what else could i do,it on a 98 f 150


You need to have two things in order to have heat: hot coolant flowing through the heater core, and air flow through the core and into the vehicle. With the engine warmed up, feel both heater hoses where they connect to the heater core. They should both be hot. If not, then you need to find out why there is no coolant flow. If you have already replaced the core, then you probably have coolant flow. Next, check the HVAC doors to make sure they operate properly, particularly the blend door. If the door is not in the proper position, then you will not have airflow through the heater core and into the vehicle.

My heater is not working in my 2001 honda civic. Is it my thermostat?


Does the heater blow cold air from the vents or do you mean the there is no airflow from the vents? cold air from the dash vents when the heater control valve is set fully hot could be an air pocket in the cooling system. The radiator sits slightly lower than the engine causing air pockets to get trapped in the engine when you replace the coolant. you'll have to purge the cooling system to restore flow to the heater core. No airflow (blower motor inop) this could be a bad blower motor transistor. pin test the blower motor circuit.

The heater in my 2006 Dodge Grand Caravan only blows warm air while on low. If the dial is turned to high it blows cold air. What is the problem?


It sounds like the heater valve is not operating. Find the valve on the engine firewall passenger side and manually open the valve. Find it by following the 3/4 inch heater hose to the firewall where it is connected to the valve. Most likely the cable ( or vaccum hose)from the temperature dial to the valve needs replacing.

Heater only blows semi warm air


Check the heater coolant flow valve is fully turned on when heater selected.
Check the temperature regulation & heat/demist air flow vanes are operating correctly,
Check motor operating temperature is as per specification- if motor running too cold replace the coolant thermostat.

Car does not blow air.


For starters, do you hear the blower motor running when you turn the heat on? If it does blow is there any airflow coming from your air vents? If the blower motor runs and there is air flow from the vents there are a few other tiems to check. Veriiffy that the coolant is full, low coolant level will effect the flow of coolant to the heater core. If coolant is full you may have a clogged heater core, or one of the blend doors ( they regulate air flow between the A/C evaperator and your heater core) may be malfunctioning or the control head(temp control) is malfntioning.
