Cavalier problems


It's a 12 volt motor for the fan...with the car cold, not running, and no key in the ignition...check to see if the fan will turn by spinning it with your hand...more than likely it is seized (the motor case may have actually rotted and swollen) and needs replacement...other than that...you may have a bad relay or temperature sensor.

engine running too hot.check coolant level, should be 50/50 antifreeze and water.replace thermostat and radiator pressure cap.check antifreeze level in the radiator,coolant level should be just below radiator cap, add coolant to overflow jug,should alway be at the full cold mark.empty coolant overflow jug will allow air be drawed in the coolant system causing overheating.if overheating happens when coming to a long stop.could have faulty engine coolant temperature sensor or bad coolant fan fuse or relay.

Have a 2002 Honda Civic. Driving around midafternoon when the needle started to rise to hot, I quickly turned off ac and the when back down. The next driving around with no ac and the needle was moving...


Sounds like the thermostat is not working properly on your car. I would suggest changing it out, and

getting a radiator flush. if that thermostat freezes shut and does not open when the engine gets hot.

you could have bigger problems, like a blown headgasket, ruin your water pump or rupture radiator

hoses. good luck!

Antifreeze light says system is low and car runs hot but antifreeze level is where it should be


Sounds like it could be a thermostat not opening. If the thermostat doesn't open then it will get hot because its not allowing the cooled antifreeze from the radiator into the engine. Your car has two circulations with the antifreeze. While your car is running it is heating up the antifreeze in the engine and when it reaches a certain temperature the thermostat opens and takes the hot antifreeze from the engine and puts it into the radiator to be cooled. At the same time the cool antifreeze from the radiator is placed into the engine to keep it cool. If your thermostat doesn't open your engine will get hot and overheat.

1999 Olds Alero 4 cyl running hotter than normal. One mechanic says it's Heat sensor that opens and closes. The other mechanic who ran car says it was thermostat that turns on dual fans. Ok well one was...


REPLACE THERMOSTAT.ITS STICKING CLOSE TO KEEP COOLANT FROM CIRCULATING THROUGH ENGINE AND RADIATOR. THE FANS SHOULD COME ON WHEN VECHICLE SETTING AT A LONG IDLE.THE COOLANT TEMPERATURE SENSOR GET TO CERTAIN TEMPERATURE WHICH WILL COMPLETE CIRCUIT PCM SEND POWER TO COOLANT SENSOR THEN TO COOLANT FANS RELAYS AND FANS.IF VECHICLE OVER HEATING WHILE MOVING THERMOSTAT FAULTY.IF YOU TURN AC AND COOLANT FANS DONT RUN CHECK COOLANT FANS FUSE AND RELAY.IF COOLING FANS DONT TURN ON WITH AIR CONDITIONER ON EITHER COOLANT TEMPERATURE SENSOR FAULTY OR PCM FAULTY.IF ALL LOOKS GOOD.IF ENGINE OIL LOOKS LIKE MILK SHAKE.YOU HAVE BLOWN HEAD GASKET.

Unable to get my 2003 chevy blazer to start. has been acting funny. the hot air has been running cold and takes the ac a long time to get cool. the engine runs hot.


get a mechanic to have a look ,water level low hence the heater is cold and ac taking a long time to cool because the fan isnt starting up when ac is turned on ,Sounds like your fan is playing up and you may have cooked the head gasket??

2002 Impala just bought toay running hot not quite


The cooling system may need to be serviced which is one of the things that is never done. The orange antifreeze has a life of 5 years and 150,000 miles and if it has never been flushed out, there may some crystal formation causing a restricted flow of antifreeze through the system. Try flushing out the cooling system with Preston radiator flush, use the dry power flush rather then the one from the bottle. Follow the instructions and replace the antifreeze with a 50/50 (water/antifreeze) mix, if you not sure how to mix it. You can buy them premixed 50/50. Too much water will boil over and too much antifreeze will gel up causing overheating. If you like you can replace the thermostat too, but that's not that easy on the 3.4 liter engines. If you go to Auto Zone you can pick up the antifreeze, radiator flush, and thermostat with the step by step instructions needed to get the job done. Keep me posted, be glad to answer any other questions you may have and good luck friend.

Engine gets hot


There are 3 potential problems:
--faulty thermostat. If it is not opening all the way by the time the engine reaches 160-180 deg F...then coolant is not flowing enough.
--partially blocked radiator caused by build up of rust over the years if never flushed as regular maintenance.
--Insufficient coolant to water ratio. Should be at least 30% or more coolant in the radiator.
--Or combination of above.
Hope this helps.

97 Ford Econoline air conditioning and vent settings blowing hot


I know from experience that if the coolant is to low ( not just the freon levels in the compresor but the antifreeze/coolant level as well) the AC system will not cool and will blow hot. Check the coolant Antifreeze and freon levels, even with the Coolant being a little low my 1998 Ford E150 Van will blow hot. After you have ruled out of these possibilities and the chance it is the thermostat most likely the problem is what Ford calls the "Flap" it controls the air flow through the vent system when you switch from Heat to AC. When the Flap is working it closes off one systems air flow so as to not interfere with the current climate selection.
