I have a 2001 dakota that is overheating. put in new thermostat, didnt help. put in new water pump, still overheating. finally replaced the radiator. still is overheating. what else can I do to fix it


Sometimes when you open cooling system, air gets in, it can cause problems with temp gage.
How hot does it get in degrees F? Is the coolant boiling over? Are you losing coolant? Use a non-contact infra red temp gun to take engine temp, At least we will have a degrees F reading. Most temp gages say hi or lo, cold or hot. I don't know about yours?
Can you check for combustion gases in the coolant?

I had a bottom radiator hose blow off my 05 equinox and I flushed the block then the heater core a d changed the thermostat put all new coolant in and still keeps overheating


What about the radiator? Water pump? Can you check for coolant flow? There could be air in the cooling system? Do you trust your temp gage? Are there overheating issues besides the temp gage showing hot, like coolant overflowing, under the hood, somewhere?

I own a 01 vw passat and my temp gage only works once in awhile and my heat also works once in awhile! If the temp gage don't work will that make me not have heat?


You likely have air in the cooling system, and the air bubbles are in the heater core, which takes heat from the coolant and puts it in the cabin air.

I have put a post in about trying to get air out of the cooling system, but essentially, unscrew the 3 screws holding the coolant reservoir down, and lift up the corner that does not have tubes coming out of it so that it is standing on end. That will help get the air bubbles out. Then start the car and let it warm up for 3 to 5 minutes at idle so that the thermostat opens. That should accept a lot of coolant. Then keep adding coolant and standing the reservoir up until it doesn't accept any more.

Takes a long time to make heat. Has a new 195 thermostat.Temp gage never goes above 130 however my no touch laser temp gage shows 171 on top hose when warmed up


Hello! I believe you have an air bubble blocking the thermostat...Since you just changed it, the cooling system needs to be blead of trapped air...Start the engine with the radiator cap off, heat on high and let the engine run until all air has escaped...Slowly add 50/50 until all air is expelled and radiator is topped off...Replace the cap with a new one...Send a comment...Guru...saailer

When heater/ac on..temp gage goes to hot when car idling but when driving holds at normal


Check to see if your electric radiator fan comes on when you are idling. You would be able to hear it if you open the hood. It should come on at around 200F and go off at 160-170F. If it is not working the car would heat to hot, when you are driving the air is forced thru the rad cooling off the antifreeze.

Put in a new water pump and thermas stat and the gage still goes to hot


Do you have access to a non contact laser temp gauge?
If so shoot the thermostat housing and see if the gauge is correct.

If the gauge is off from the laser then replace the engine coolant temp sensor,
If the gauge is correct then double check the thermostat installation,is it in backwards? or maybe you got a bad thermostat.

did you flush the entire system when you replaced water pump?

It will probably be your thermostat that is jammed open , try fitting a new one , the thermostat is located in the housing on the side of the engine usually just above the gearbox , trace the top radiator hose to the engine and you should be able to find where the thermostat is ,
