What should you check first if you have no leak and changed the thermostat in 97 escort and have no heat?

I had no heat in my escort either. A new thermostat, cooling system flush, new heater core, another new thermostat, ect. but nothing worked. Still only slightly warm air from the vents. The thermostat housing has a thermostat bypass in it. This bypass is always circulating coolant through your radiator. I plugged mine off with a thermostat gasket and now my car heats and blows hot air with no complications. Good luck.

There could be several things wrong with the system that the thermostat gauge is connected to. You could check to see if the gauge is working correctly. If the gauge works fine, then it could be the housing that the thermostat is mounted to. It could also be a faulty bypass valve near the thermostat which prevents the engine from heating up. Check these places to see what may be wrong with your escort.

My 2001 Nissan frontier 3.3 v6 engine is overheating. I changed the thermostat but it still overheats.

check the radiator cap, needs to be 13psi at least, i believe. that was my issue with my old ford, the cap was shot

Check your spark plugs for water. they should all be light tan in color. If they are do a compression check, there should be no more then 10 lbs.differance between all the cyl.'s.

You should check your Toyota Tacoma's owners manual. There should be a diagram for the location of your thermostat.

U take the thermostat out, get a pot of water, put the thermostat in it and start it to boiling. When the water reaches the temp that the thermostat is designed to operate at it should open , if not , it is defective

Check the thermostat first. I had an intermittent overheating problem on my 02 for almost a year, changed the thermostat and it never happened again. If that doesn't work, secondly I would check the water pump.

Check your connection with the fan on/off sensor. Should be located somewhere on the thermostat housing. Sometimes if there is no signal, the fan will stay on (failsafe). Could also be the sensor

First check the water level. Low level will not get to the heater core. Change the thermostat. If you recently changed the thermostat, bleed the coolant system.

Check the Blender door... Also check the temp knobs they make be broken.

What temp. thermostat did you put in? Try a higher temp. one. or check to see if heater core is clogged

It could be one of several things... 1. Check that it is the correct thermostat for the unit. It may require one that is a millivolt thermostat. 2. Check that the thermostat is level if it is a mercury switch. use a torpedo level 3. Check the amp draw on the heating element. 4. Check continuity through the coil. 5. Check high limit switch is operating properly. 6 Check wiring for polarity on the relay. 7. Check the wiring diagram to ensure all wires are in the right places. 8. Put the old thermostat back and see if the problem is still there. I'm an installer, I've swapped out electric furnaces because of this issue.

Typically that will be an issue with the thermostat. Check the setting, and if it is where it should be, then thermostat will likely require replacement.

If the engine is taking a long time to warm up or the gauge registers low heat the thermostat probably is stuck open and needs to be replaced. If the engine runs hot check the temperature of the upper radiator hose. If it's not hot the thermostat is stuck closed and should be replaced. If the upper hose is hot it means the thermostat is open and working. Cooling problem could be restricted radiator.

There are several things that can cause your cooling system to overheat. The next thing you should check is the thermostat. A blown head gasket can also cause the system to overheat.

check thermostat and temp sending units there should be two

You should check the thermostat and the fuse for the heater.

Check where the top radiator hose enters the block. There should be a housing that can be removed with 2 bolts. That should be the location of the thermostat.

Check the fuse box cover, it should be labelled with its own diagram.

Check your heater core and thermostat. The thermostat may be stuck open. Does the S10 run hot or cold?

That depends on the thermostat. If it's a 185 thermostat, the engine should run at 185. If it's running too hot, check the thermostat, radiator and water pump. If it's running too cold, replace the thermostat.
