To find out if it your thermostat check the bottom radiator hose and see if is hot if not it is your thermostat and also the water could be the problem locate the water pump on the side of the motor if u see water leaking out of the shaft of the pump it is likely u have a bad water pump also

No heat in Ford Aerostar gage does not move. Heater core was flushed and new thermostat was put in

Just a guess, but I don't think you did this yourself. Take it back to the mechanic and complain.

You didn't say if this was the result of the flush and thermostat change or if you had the problem previously. I tend to think this is a thermostat problem still. It is possible the mechanic simply forgot to install the new thermostat (remote, but possible).

If you have no heat and the temperature guage is pegged cold, the engine is not reaching operating temperature. It is the thermostat's job to regulate this. Does the radiator get warm?

I would take it back to the mechanic if you trust him, or try another if you don't.

I have a 200 Pontiac Montana and today it overheated into the red! Not sure why! I also don't have heat unless the RPMs are above 200. My fan don't kick on unless the air is on. 2 months ago I...

With the car running because it reduces the back pressure have someone that knows how to do it remove the cap from the radiator and see if the radiator is full, not the bottle but the radiator itself. If the antifreeze is not moving from the bottle to the radiator it will overheat. Not having heat unless you rev the engine makes me think the radiator is either not circulating the water or it is low.

Heater problem

Put a meat thermometer taped to the upper radiator hose by engine. Check temp when fully hot should be minimum 180 degrees or higher. Turn on full heat and see what the temp of your heater hoses are going through the fire wall they should be the same temp as the engine was. If one side of the heater is cold take off hoses when cold and hook to garden hose on cold side first and flush out heater core. I don't think thats it. If it is hot everywhere but inside one of your mode motors is not opening the right door under the dash when looked at from drivers side two motors. They are interchangeable but have to be calibrated

Over heating. Have bypassed thermostat and still over heats. Blows water out overflow tank but lower radiator hose is not hot. Can feel it is just warm.

I don't understand what you mean when you say that you have bypassed the thermostat because it is impossible to do, by what you are saying I think that the thermostat is'nt opening up &needs to be replaced ( are you know what & where the thermostat is)....hope this helps........cheers.

02 stratus with the 3.0 liter in it, noticed the heat was getting weak, then changed the thermostat and now theres no heat and the coolant level is full, please help

New thermostat may be faulty. May be stuck open. Remove rad cap and with rad full and eng cold - start vehicle. The coolant should not circulate until eng reaches design temp of thermostat. Let me know if this helps you.
