Its either the thermostat or the head gasket, doing a compresson check will eliminate the head gasket. the thermostat is a cheap part and is easy to replace and if its overheating its stuck closed never allowing coolant to circulate through the radiator.

2010 kia soul if thermostat is not working what problems can it cause


Engine overheats if the thermostat is stuck in the closed position. Engine can be damaged permanently. Engine takes a long time to heat up if the thermostat is stuck in the open position. Defective thermostat in both situations.

Temperature gauge stuck


-You mean your car never get hotter than 60*...?
If so, the thermostat is open all the time. Or stuck at open position.
Possibly need new thermostat.

On my 2004 Grand Prix, my car has to be running for at least 45 minutes for some heat to work.The yellow light by the heater blinks while the blower comes on and goes off repeatedly until the light is...


It is possible that your thermostat is stuck open. Normally, the thermostat remains closed when starting cold, confining coolant to the engine block and cylinder head until it heats up. Once the coolant in the block is warm (usually within 10 minutes), the thermostat begins to open and let coolant flow into the radiator to cool it down some. A properly operating thermostat will continue to cycle until the coolant reaches the operating temperature of the thermostat--usually around 180 deg F. Then the thermostat will continue to adjust its opening to maintain that temp.

Thermostats can get stuck in both closed and open positions. When stuck closed, the engine will quickly overheat. When stuck open, the engine will take forever to warm up--especially in cold weather because the coolant is continually pushed into the radiator and cooled off before it ever has a chance to get warm. Changing the inexpensive thermostat may help correct your condition.

I am having a promble with my heat i replaced the heater core and still no heat



Your thermostat could be stuck in an open position. This will result in your vehicle being underheated. Typically, a thermostat opens only when an engine reaches a certain operating temperature. If a thermostat is stuck in the open position, radiator coolant flows into an engine before it reaches normal operating temperature. This prevents adequate engine warming and results in engine underheating. DIY repair costs: $5-$10

Truck will not heat up. I have put a new thermostat in. Also it has the right mixture of antifreeze, and clutch fan is working. Radiator, and hoses don't get warm!


Make sure the new thermostat was not put in backwards, tap on thermostat housing lightly could be stuck in the open position.

Lots of air no heat. Coolant was lower have added that. still no heat. any ideas on how to repair... is this expensive. 2006 Honda CRV I have less than 25000 miles on it.


Have you checked the thermostat? If the thermostat has gone bad you may get one of two possible extremes. If it is stuck in the closed position, your vehicle will overheat. If it is stuck open, you will have no heat. SAFETY: DO NOT DO ANY OF THIS WHILE THE ENGINE IS HOT!

Fortunately, this is an easy and relatively inexpensive fix if you do it yourself.

To find the thermostat housing, follow the radiator hoses back to where they enter the engine block. You should see a hemispherical housing held on with two bolts. That is the thermostat housing. On your CR-V, it should be on the downward pointing hose. When you remove the housing, you will lose coolant, so position a catch basin to receive the coolant that comes out. Remove the bolts, lift the housing (you may need to pry it with a screwdriver). Remove the thermostat, being careful to note how everything was positioned. Inspect the thermostat; If the circular piece at the center attached to the spring is open (ie pulled away from the center) on a cold engine, the thermostat is bad and is stuck in the open opsition. To install a new thermostat, clean off all the old gasket and install the new one that comes with a new thermostat (if you do not clean off all the old gasket before installing the new one it will probably leak). Put the new thermostat in place in the same position as the old one, replace the housing and refill any lost coolant. God bless and good luck

I have no heat coming out of the vents. Blows


If the temperature is cold outdoors, this can be a symptom of a stuck open thermostat. With the thermostat stuck open the engine never gets warm, so it won't give good heat. It's not expensive to get a new one, and they are easy to replace, so take it in and have it checked. Another symptom of that is very low gas mileage in the cold weather.

The thermostat needs to be replaced. When this happens, the thermostat is stuck in the open position and is not moderating the coolant temperature to where it should be. Replace the thermostat and coolant if it's older then 5 years or has over 150,000 miles. Good luck and make sure the new coolant is mixed 50/50 water/antifreeze
