Unscrew the cap from your overflow and leave it off over night. the air in the system will naturally want to rise. the air pocket will be out by morning. make sure to fill you coolant back up then!

Whoever told you the temperature gauge on cavalier is normal 3/4th is the lie. It is however in operating temperature range but on the hot side. Have you flushed your coolant and replaced thermostate, and gotten air vapor locks out.

After replacing the thermostat, you must bleed the air from the cooling system.

To bleed air from the 2.2L and 2.5L engines, remove the plug or sensor on the top of the thermostat housing. Fill the radiator with coolant until the coolant comes out the hole. Since the plug is made out of steel and the thermostat housing is aluminum, it is a good idea to apply an anti-seizing compound or Teflon® tape on the plug threads prior to installation. Install the plug and continue to fill the radiator. This will vent all trapped air from the engine.

Any trapped air in the heating system will have to be displaced by coolant. Once the cooling system is filled, with the radiator cap off, turn of the heater at it's highest setting. Start the engine and allow it to reach operating temp. You should see a drop in the coolant level as the air in the heating system is displaced by coolant. Add coolant to the proper level and replace the radiator cap.

Keep a close eye on the coolant level for at least the next couple of weeks. The cooling system is a "closed" system. Any significant decrease in coolant level indicates a problem.

If you have any questions, let me know.

Please take the time to rate this solution.

Drive safe and be warm.

SOURCE: engine light comes on and says engine overheating

Could be three things: Hopefully the first...
1. radiator fan not blowing. (most likely)
2. Radiator clogged (not likely)
3. Head gasket blown... (very possible)

If #1, system cannot detect fan not blowing. It may be the fuse or the relay switch, disconnecetd wire at fan, or burned-out fan motor.
If #2, Flush radiator
If #3, you will see WHITE smoke out the tailpipe and excessive water drops.
Your new oil will have a "milky" look (check the oil dipstick). That is water.
When engine is COLD, remove radiator cap and start car. You will notice high-pressure "bubbles" squirt out of the radiator, even before the engine warms up.

I hope it is #1. and that this is helpful.

P0128 is coolant operating temperature operating too low. This can be contributed to the Thermostat stuck open or faulty electronic radiator fan clutch. This is common, I had the same issue and replaced the thermostat and fan clutch and had the clutch re-programmed (required) at the dealer. As for the P0410, check the air pump fuse, if blown it will set this code on. Also check the air pump hoses for water and cracks. Hopefully this helps!!

My 2004 Trailblazer overheated,ilooked under the hood to see the fan was wet. water in the radiator is still circulating.Is this a hole in the radiator or is it the water pump?


Check for the leak when running but not moving. Is the fan electric, and mounted on the radiator? If it is, I would suspect a radiator leak. You might pull the fan assembly off to get a closer look at the radiator.

When I turn on my AC on my Trailblazer -six cilender 2004- the temperture goes up to Hi within a few minutes. I put in a new Radiator and new fan,but this didnot solve the problem


Did you replace the thermostat and bleed all the air out the system also? The fan clutch needs to be checked to make sure the fan is fully engaged or the engine will overheat.

U have to operate the engine at all kinds of diff speeds and drive modes, it is called a OBDII drive cycle, here is how u do one.
1. As soon as the engine starts, idle the engine in drive for two and a half minutes with the A/C and rear defrost on. OBDII checks oxygen sensor heater circuits, air pump and EVAP purge.

2. Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. OBDII checks for ignition misfire, fuel2_bing.gif trim and canister purge.

3. Hold at a steady state speed of 55 mph for three minutes.

OBDII monitors EGR, air pump, O2 sensors and canister purge.

4. Decelerate (coast down) to 20 mph without braking or depressing the clutch. OBDII checks EGR and purge functions.

5. Accelerate back to 55 to 60 mph at half throttle. OBDII checks misfire, fuel trim and purge again.

6. Hold at a steady speed of 55 to 60 mph for five minutes.

OBDII monitors catalytic converter efficiency, misfire, EGR, fuel trim, oxygen sensors and purge functions.

7. Decelerate (coast down) to a stop without braking. OBDII makes a final check of EGR and canister purge

Hello, i have a 2004 hyundai accent and my problem is that sometimes,the temp gauge will show the car getting hotter to the red.then it will slowly go back to normal.it stays normal most of the time.does...


Could be a faulty sender, but first go through the checklist following:-

1) Check engine cooling fan/s are operating as required when engine temp rises above cut-in threshold - check fan control relay is ok,
2) Check for collapsing radiator hose on suction side of water-pump when motor revs raised above idle.
3) Check coolant reservoir pressure cap is serviceable,
4) Check coolant system is properly filled - carry out any bleed off procedure specified to clear any air locks- (ensure heater core coolant flow is turned on).
5) Check condition of radiator core:-
i) for blockage of air flow to (bugs/grass etc),
ii) for core internal blockage to coolant flow,

Had the same problem, replaced the ambient air temp sensor in front of the radiator. Cost is like 10-15 bucks. Don't worry if temp doesn't change right away. Took me about 5 miles and then it worked great.

2000 Intrigue Oldsmobile over heating


I have a 2000 Intrigue that had the same overheating problem only when it gets below 0 degrees. I read many forums on this matter and it only got me more confused. It had thumping in the heater hose lines when it got hot. So here is what I did to cure the problem....I first installed a new thermostat that I purchased from NAPA Auto-$43. I noticed that it has a small one way valve built into the housing. I took a 1/8 inch drill bit and drilled down through the hole to make it a 2 way hole so coolant could get through (and air could escape when bleeding the system). I then took off the purge tank and flushed it out with hot water to get all of the crud out of it. When I reinstalled all of the hoses and thermostat, I coated the gasket seal and inside the hoses with high temp RTV. I also took off those wierd squeeze clamps and used the screw type hose clamps. I suspected that it was drawing air into the system when it cooled down and with the RTV and new clamps, that problem was eliminated! I reinstalled the surge tank and filled with 50/50 mixture of Dex Cool, then started the engine. I opened the bleeder valve on the top right corner of the radiator and left it open until a good steady stream of antifreeze came out. I kept putting antifreeze into the surge tank until it came up to the full cold mark. Then I left the pressure cap off and drove the car for about 10 miles at normal speed. During this time I had the heater running on high. When I stopped the car I added enough antifreeze to bring the surge tank level to full hot and put the pressure cap on. I then drove it for another 10 miles or so and checked the level, right on the full hot line. By the way, I also put on a new pressure cap. For $7 it was worth the money. I drove the car around for about another hour and the temp gauge only got up to a little over 1/4! Oh, I also put a new serpentine belt, just because the old one had 60,000 miles on it. So for $43 (new thermostat), $7 (new pressure cap), $12 (more Dex Cool), $24 (new serpentine belt), and $20 (new clamps, High Heat RTV, etc) the problem is fixed!! The reason I drilled out the hole in the thermostat housing was for air to escape when bleeding the system. This was the one and only time I have had problems with overheating, just in real cold temps, and I hope it never comes back! So for a little over $100 (MUCH less than a garage would charge!), you can do the same thing with a few tools.
