If its the thermostat your lucky easy fix just replace it but wait until the engine is cold the bolts are a nightmare to get to you have to take off air hose and disconnect a couple coolant hoses move them aside to get to the thermostat housing on the side of the engine tricky getting to that bolt.

if its the head gasket flush the radiator with flushing agent
first drain the coolant from bottom radiator hose replace with flushing agent run car idle about 10 minutes then
remove the thermostat replace the thermostat housing then fill the coolant back up leave room for blue devil head gasket sealant about $65.00 follow the directions to the tea run for 50 minutes if it doesn't work that baby needs to get in the shop
hope this helps don't forget to rate if I was helpful.
good luck

run car till over heat or get hot stick your hand in the middle of the radiator if it aint that hot no water is going though the motor to cool it so the thermostat is blocked

Hey Alexis,
Sounds like your thermostat is stuck.. they cause the symptoms you describe... they are inexpensive in replace,, Have your coolant system flushed and refilled with fresh antifreeze/coolant.

I have a 2004 Pontiac Sunfire. When the car is in idle the air blows out hot and the Temperature gage rises and the car over heats. When the car is moving the air blows out ice cold and the temperature...


Sounds like your cooling fans on the radiator are not working. The fans are activated by a thermol switch on the engine or radiator reading the coolant temperature and an A/C switch. When the coolant is too hot the fans should activate cooling the system down. And, when the A/C is on the fans should also activate in order to cool the condensate so the A/C would work.

When you are driving, the movement of the vehicle throught he air is providing enough air flow to keep things cool and functional.

I would check the radiator fan fuse or fuses first. If those are OK I would try to run the fans with 12 volts and a ground that I supply just to see if the fan motor(s) actually run when powered. If the fan don't run when powered then the fans are bad and will need to be replaced. If the fans do run when you power them manually, then something is not allowing the power to activate, like a relay, control unit, or wiring.

It will take a little diagnostics, but it is not too difficult to chase it down.

Yes it is normal just no hot air


1. When setting the temperature to MAX, blower level to FULL and outside air Vent CLOSED, no hot air comes out after 2-5 minutes?
If YES, when did you last flushed your radiator and is it full?
2. if more than 5 years ago, flush radiator system, instructions are usually in Owners manual. Use a bottle of Radiator cleaner, run egine hot for about 10-15 minutes, carefully open petcock in bottom of radiator to flush out radiator, WARNING, careful as flushed coolant would be boiling hot. As sson petcock is open and water start to flow out, carefully open radiator cap to enhance flushing flow. Use garden hose to fill radiator while flushing until water coming out from petcock is cold and clear.
Once clear, start engine, turn heter full and blower full blast and keep hose in radiator flowing full, leave petcock open until clear water flows out again. Once clear waters comes out, turn off engine,turn off garden hose and let water drain empty radiator. Once it stops flowing out, close petcock snug and put radiator cap on, pull off radiator coolant catch bottle, clean bottle for any debris and dirt. Drain any water, leave bottle empty and put it back onto its place.
3. Fill radiator with 1 gallon (4L) of concentrated coolant, top up radiator until full, fill catch bottle with concentrated coolant, start engine and keep it overflowing until no bubbles comes out and the radiator is fully hot. Once it is flowing good, close and connect everything. Drive with it and keep catch bottle filled as necessarry.
Good luck. Give as vote and good comment if this advise solve youor problem. Thank you.

Heat is not working - coolant was low so filled it.... problem here... heard something about an air pocket


If you dont have an external coolant leak anywhere under your hood that has shown up on your driveway it could be the intake manifold or the headgasket leaking. Also check the thermostate to solve the heat issue.

Engine Cooling problem 2003 Dodge Caravan 6


It needs a thermostat and a coolant flush, in the worst case scenario a head gasket may be blown or leaking, have your mechanic do a coolant flush,thermostat, and leak check.

Weird humming noise & over heating while sitting in traffic


The humming is the noise the coolant makes when the car overheats and forces open the relief valve in the radiator cap and flows through the small hose to the recovery bottle., it you had all this work this done only 2 things can cause the issue, one is a problem with the cooling fan, the other is a blown head gasket, which I suspect is the problem, before you flushed the system was the coolant rusted?
