    I have the same exact problem.

    I disconnected the battery for about an hour to clear the car's computers and followed the Owner's Manuals in the Maintenance section to allow the computers to relearn. This seems to have resolved the problem.

    Good luck.

    The problem began to re-occur so I broke down and took the car into the dealer to read the codes for the check engine light. They told me that the thermostat needed to be replaced and wanted $650, plus parts to do so. I paid the $95 for the diagnostic test and went to Kragen and special ordered the thermostat and gasket for $30. It took me a little less than an hour to replace it. The old one had a series of cracks around a brass bowl that was causing it to "hang up" in its housing causing the occassional overheating. Apparently waiting a few minutes with the engine off allowed it to release.

    Hoped this helps.

Check engine light comes on and then the temperature gauge goes up to hot

Mine did it too.... The problem is the Engine Power Relay.

The Engine Power Relay is in the relay box in the engine compartment. Aftermarket relay is cheap, but the original Ssangyong part will last many years longer.

Hope this helps.

When the temperature outside is hot and I'm running the air, the temperature gauge starts moving into the hot zone. If I turn off the air, it goes back to normal. I've had it worked on several...

make sure that the coils, ( the ac radiator ) are clean , blow them out with an air hose if you can get a hold of one, also, make sure the ac fan is coming on, it may start , but the sensor may be bad allowing it to turn off too soon , a normal rise in heat is expected when using the AC but if it is too hot you should feel the motor start to run rough, if its running fine, and the temp does move back to normal when the ac is turned off, and a qualified mechanic has checked it, your probably ok, you could have a sensitive gauge, , If the normal range of the gauge moves to hot and back during normal driving without the ac on, that would show the thermostat is also working

I don't think it's the thermostat, so much, as the circuit for the temperature gauge which includes, wiring to the cts (coolant temperature sender), the cts itself, and the gauge. It's likely a wiring problem if it randomly bounces from normal to hot while driving the vehicle or standing still.

Does the car have a normal oil level on the dipstick? The behavior is consistent with a broken timing belt except for the part about the temperature gauge going to the top which would indicate overheating or a faulty gauge.

How to check thermostat on a 1999 silverado z71

When the truck is cold, with the engine off open the hood and search for for the upper radiator hose, look for a place on the hose to put your hand on it, a place that it's not close to any moving parts, (radiator's fan, and pulleys in front of the engine) now that you have fine a good spot on the hose to check the thermostat, go ahead star the engine and just wait while you keep your hand on the hose.
Ones the thermostat gets hot, it will open letting hot antifreeze flow into the radiator that's when your hand will feel this hot change on the radiator hose. It's a good time to take a look to your temperature gauge, it's too hot or too cold?
if the gauge moves higher than normally does, and you didn't feel a hot change on the hose, that means you have a bad thermostat that it's not opening on time or it's not opening at all,
if the gauge it's below than normally does, that means the thermostat it's open all the time

Engine does not appear to be hot. Gauge says extreme heat

try replacing your temperature sending switch. That it what tells your gauge or idiot light where to read or light to come on. It may have a short in it. Or a short between the two.

Coolant leaks

That's probably coming out of your coolant return bottle. With rad cap off & engine cool, look at your level in the rad, if necessary top it up to an inch or so from top. Start engine, turn heater(not defrost) on and let it run until up to normal operating temperature. Keep an eye on temperature gauge & rad level. When it's at normal, watch for good flow going through rad when thermostat opens. after flow slows down,(thermostat closes) top it up if needed. If you watch 2 or 3 times for flow, and gauge doesn't go over normal, then put cap back on, then fill bottle only to mark for warm or hot engine, with coolant. If gauge goes up over normal from there, replace thermostat, and I'd get a new rad cap too. If that has electric cooling fan, make sure it comes on shortly after you see thermostat open & coolant flowing through rad.

Electrical failures on 98 Sunfire, 2.2

ABS sensor : If you've been in the snow & slush lately, stop at a carwash & rinse the back side of your wheels off, front, back, over, under, as much as you can, it may be tripped due to sensor covered in dirt or slush and not giving necessary signal. As far as cooling fan coming on, let it sit & idle & watch your temp gauge. When at normal operating temperature + or - a few degrees, it should come on, but watch & see if gauge goes too high towards hot, and it doesn't come on, have fan operation checked.
