    Coolant in the oil is rare, My basis for this, 30 years of auromotive repair, 100's of head gasket jobs.

    this goes far beyond a simple thermostat, you have blown the engine's cylinder head gasket.

Let's don't say that it is the head gasket yet. There is a heater core that could be bad. First, replace the t'stat. When putting water/ antifreeze back into the car. Add the water to the outgoing hose of the radiator that feeds into the engine. This will insure you get water into the engine. Of course you will still add water to the radiator itself. Let the engine run while you are adding water. It won't overheat while you are doing this. If you do have a blown headgasket, you will have water in your oil. Does the gauge go to the red at low RPMs only? Lt me know what you find out.

    The head gasket repair can be very expensive. Hopefully, there is no more damage inside the engine. This may run upwards of $1000. A lot of labor involved here and some parts. The best of luck.

Heat/defroster doesn't work. blower does.


As far as heat, does the engine reach normal operating temp? Do the heater hoses get hot? Can you check circulation through the heater core?
Check the actuator doors under the dash, see if properly operating?

If you have a viscous fan hub then have it replaced as it is not drawing air through the radiator at idle or slow speed (crawling traffic). Check that are no air locks in the system as they will cause heating problems.

Auto coolant hot temp light comes on and temp gauge goes up more when idling at a light


If temp gauge is going into the red on a 3.4 engine it must be shut down or head damage can happen within minutes. I have a Monte Carlo that was overheating. I changed everything, thermostat, water pump, belt tensioner, radiator, all with no result. It would start out okay on a cold start but then I would come to a red light and the temp would creep up. Higher and higher until it neared the red zone. The heat would run cold. Most of the time, as soon as it was about to touch the red it would start to drop, the heat would blow hot again and all seemed okay but not for long. This would get worse and worse until the red hot light came on and I found myself on the side of the thruway. This problem is a blown head gasket. I had no other obvious signs, no white smoke from the exhaust, no oil in the antifreeze. I even changed the intake gaskets. Head gasket issues are common on the 3.4 liter engines.

My 1999 Chevy Malibu runs hot? It started when it overheated. We changed the thermostat, then water pump, then temp sensor gauge and the temp gauge goes high but only when the heater stops blowing hot...


Air pockets will make the guage do that, and also cause your heat to come and go. Also, a poor radiator, as in rotting, or plugged up, will cause high temperature issues.

The high temp gauge will max out and then back to normal. Also the heat will not work then kick in all of a sudden.


Let me guess...When the temp gauge goes hot, the heater goes cold, and vice versa? Check your coolant level first in the radiator (when the engine is COLD) and also in the overflow reservoir. ONLY use a 50/50 mix of coolant and water, using the same COLOR coolant that is already in the radiator (if it's green, buy green, if it's orange/red, buy orange/red). Next thing to have checked/replaced is the thermostat which is inside the cooling system of the engine. Finally, and the most expensive, have the water pump checked/replaced.

I would put my money on low coolant level in the radiator. As the engine heats up, the coolant will "surge" through the system as the water pump tries to **** air through the system due to low coolant level. If the coolant isn't flowing, the heat can't escape the engine block and it starts to overheat.

Over heating on gauge, both fans on rad.


I would say check your coolant level, and change your thermostat. And see if it is high fans or low fans when they come on. There is a fan control relay down on the drivers side frame right under the air box that goes bad too if your fans arent working quite right to check if all else.

1994 Lebaron Convertible No Heat, High Temp Gauge


The heat is made in the engine so if the engine is overheated and nothing else is hot, the water is not moving.
I would have suspected a thermostat also.
I would guess now that you have a dead water pump.

Thermostat?


It actually sounds to me like you're low on coolant. My Jeep leaks coolant and whenever it gets low the temp gauge will go real high and then drop, and the heater doesn't work well. This is because the cooling system of your car is supposed to be a closed system, full of coolant and no air. When coolant leaks out, the space it used to occupy is now occupied by air, which does not transfer heat well. When 'air' is passing through your cooling system, no heat can be transferred from your engine to the heater and radiator, resulting in a hot engine and no heat at the heater. Then when a pocket of water passes through the system, the temperature gauge quickly falls as the water absorbs the heat from the engine. The hot water that cools the engine is where the heater gets it's heat from as well, so when water passes through the heater core, the heater works, but when it's filled with air, it doesn't.

Hot water runs through the heater core regardless of whether or not your thermostat is open or closed. That's why your heater works in the winter even before the engine is at normal operating temperature. The fact that the heater stops working is a good sign that the thermostat is probably not the culprit.

As for the water pump. If the water pump was bad, your temp gauge would go into the red and stay there. Water pumps generally don't work intermittently. Either it's good and ot works, or it's bad and it doesn't.

However, if you are in fact low on water, as I suspect, it means you probably have a leak somewhere. The leak could be in the water pump housing gasket, so depending on where you take it for repairs, they may try to sell you a new water pump anyhow. So just beware of that.
