    The temp. gauge started going up and down incrementally from the half way point up to about three quarters. I have no external leaks. I topped off the coolant. There are no error codes. The fans both come on. My next step may be thermostat or radiator flush. Any suggestions?

You may be just low on water. Check your water level and top off with antifreeze.

2002 dodge intrepid the heat blows but doesn't get hot! Had the thermostat replaced but still no heat. What would be the problem?


either a heat switch is not switching heat to the compartment or else the thermostat in the cooling system is defective. when it is not open it does not let hot water to the internal heating system, has your engine been overheating or running hot? also as this would be a symtom.

It only gets hot when going speeds faster than 65 or 70 mph for 5 min or so. I can push in the clutch and coast and the temp gauge will start to climb rapidly let out on the clutch and cool back down. I...


Hi

Your engine thermostat is stuck open and this is what is causing the problem. You will need to have a new thermostat fitted - Usual cost is between $15 to $30. Maybe less depending on thermostat type.

How the thermostat works is it remains in a closed position within the engines coolant circulating system to allow the engine to heat and reach its optimum operating temperature. The thermostat then opens to allow the coolant to circulate freely. When the thermostat becomes faulty it fails to respond to the temperature of the coolant. What has happened it that it has opened and is stuck in an open position allowing the water to circulate too freely around the engine - you will see a brief rise in temperature when the engine is worked hard but as soon as you come to rest the temperature falls back again as the thermostat is not closing when it should.

Solution - replace thermostat and all will be well!

Hope this helps. Please remember to rate my answer. Many Thanks.

No heat at all


Ensure your cooling system is full.
With the engine at operating temperature feel the heater hoses going into the firewall. They should both be warm.
If all that is ok inspect the heater temperature door. The door that operates when the heater valve is actuated.

94 dodge intrepid blows kinda warm but not very warm what do I do? We changed the thermostat


Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

Car over heated and shut off . was low on water .


Make sure when you add coolant to system, that you have heater running while filling it and be sure to bleed all air out of system. Keep a real close eye on coolant level for a while as you may have caused worse damage, and if you keep having to add coolant. It would also be smart to change thermostat before refilling system, but if not, keep a close eye on temperature gauge for a while to make sure it doesn't go too high, or jump erratically from cold to hot, indicating faulty thermostat. Check oil often as well.

2002 Dodge Intrepid has no heat


Radiators do not "go out". They leak or they don't... that's it. You wasted money changing a radiator if you aren't loosing coolant. The thermostat (~$10) is all you needed to change.

Inconsistent heat.


The first thing i would do is replace thermostat and bleed cooling system, then re-check, It sounds like you have a defective thermostat.
