Need to check the thermostat on 1994 dodge caravan

Best to get rid of it

You can do a combustion leak test,
to check for a bad head gasket

Heres a belt diagram for your 1994 dodge grand caravan with a 3.3 engine, hope this helpful.

you pinched a wire into the bellhousing between the tranny and block!!! it! happens

One or more of:

1. Your coolant level is low
2. Your thermostat doesn't close and needs to be replaced
3. The valve from the cooling system to the heater core is stuck
4. Your heater core is clogged

change your thermostat

Did you bleed the cooling system after refilling the radiator ? to bleed the system, fill the radiator with water and coolant. Run the engine until it is at a good temperature. Then turn off the engine and look for a bleeding screw at the oulet of the thermostat housing and turn it with a screwdriver counterclock wise. The trapped air will go out and coolant will start coming out. refill the radiator and repeat until only coolant comes out and no air.be careful not to burn yourself.

HAVE THE BLOWER MOTOR WIRING CHECK

I had a grand caravan that did the same, and it would not heat until I added the antifreeze. It sounds funny, but I hear, that the water turns to steam at the top, and does not circulate well without antifreeze/antiboil.

Yes, this is very normal. You'll replace the front 3 times before you'll have to replace the rears. The reason for this is because 80% of your braking is in the front. There is nothing wrong with your brake system.
