Take cover off of your thermostat,it should just snap on and see if your stat has a mercury switch in it. It will be a small glass vial with a small amount of mercury in it. Check to see if t-stat is level if not then loosen mounting screws and level stat then retighten mounting screws.If the mercury switch is very far out of level it will never read close to actual setting. Thank you

Heat is not acting right


If you checked properly and coolant/rad isn't getting hot, coolant is up to proper level, then I'd replace thermostat.

Temperature gage fluctuates when driving my 1996 mazda protege


Well sounds like first start your car record where the temp needle reads, then let the engine warm up (with out driving) then rev the engine to about 3500-4000rpm a couple times does your needle move at all record then hold your rpm at 3500 for about 5-10 sec does this get the gauge to drop? sounds like you may "if not over heating at all and coolant level and circulation is good" have a circuit problem, you can test this by going to auto zone and ask for a scan to be done on your car when the plug into your OBD 2 ask them to go into DATA STREAM and then check to see what temp your ECM thinks the engine coolant is at does it match your gauge at idle and at 3500rpm if not its a faulty circuit

Replaced thermostat and sending unit .check engine light went out .on incline have 3/4 gage warm, when level goes 1/4 on gage cold air,temp wont get hot.or 1/4 gage.could this be computer if so how to...


Not computer. You have air in the cooling system. Bubble is moving around. Park on an upward incline, take the radiator cap off, run the engine and keep the radiator full. Let it warm up and let the thermostat open (until you see flow in the radiator). Then fill to the brim and keep full until it stops going down. Also open any bleed ports you can find in the cooling system (there may not be any) and let any air out of them. Let the engine run and check for any bubbles that continue to come out. If bubbles continue to come up, you have a blown head gasket that is forming the bubble and causing the heater and temp gage issues. If bubbles do not come out, maybe you have fixed the problem by getting all the air out. Please let me know if you have any questions.

I have a 1993 Acura Ledgend. For some reason my heater does not continue to blow hot air, it does for a few minutes and then begain to blow cold air. It does this often now. It works and then it blows cold...


first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure

Temp gage normal warms up and then goes red for a few seconds


is the thermostat sticking from cold operation?
have you tried replacing it to see if it still happens?
if it does still happen, could be temperature sensor
the sensor might be cheaper and easier to replace 1st
