Does it have elec or clutch type fans?,elec fans can fail due to relay or sensor issues.
thermostat may be stuck,how many miles has car done?
there may be a build up of bugs or dirt on the front of the radiator.
you may need to have the codes read by a scan tool to check ECU system

SOURCE: 02 Alero not overheating, no heat

When you say not leaking antifreeze has your coolant level gone down at all? and is it that you have seen no leaks where you park it? What worries me is you can smell it when warming up, have you felt the interior floors to see if damp and do you get any condensation if put blower onto screen, if so then heater matrix is leaking if not could be down to headgasket and/or cylinder head leak.

The most likely source of your problem is NOT a head gasket or cracked head, but the black plastic plenum or "upper intake manifold". These GM engines tend to melt, crack, or warp the plenum because of the hot EGR tube sticking up through the plastic.

If water is getting into your oil (milky looking), your lower intake manifold gasket is probably cracked. Once the plenum is off the engine, there are only about a dozen bolts holding the lower intake manifold on. When you replace the gasket, it is recommended to use an ALL METAL gasket with rubber seals to prevent this from happening again. The metal gaskets cost about $80 where as the plastic ones that are prone to breaking cost about $45. Better to fix it right once than to do it wrong several times.

Also, if you are still using Dexcool coolant (orangeish), be sure to change it every two years or so as it does bad things to seals when it gets old.

Could be both your water pump and thermostat are faulty. Start with the simple and replace the thermostat and also did the engine over heat while you were stopped or in stop and go traffic, if you were then you may have a blown fuse or bad cooling fan relay that needs to be addressed. Check to make sure your Cooling fan is working, you can test this buy turning on your A/C on full and the fan should come one the same time your A/C clutch activates. If the fan does not function, inspect the electrical system to the cooling fans and replace the thermostat to ensure there will not be any issues in the summer time. Thermostat are know to go bad when they are over heated.

Hello,

when the car overheats, is there still water in the radiator?

If there is water in the radiator and the car overheats, then it means there might be some dirt or blockage in the radiator or condenser.

When the car is on the motion, air passes through the front and assists the fan to cool the engine. There are situation whereby air doesn't have free flow because of blockage in the radiator and condenser. Dust and debris can cause blockage. If this be the case, have your radiator washed thoroughly and cleaned.

If there is no water in the radiator when the car overheats, then there is a probably a leakage from the water pump. Or maybe your fan isn't blowing properly. The fan might be blowing weak air.

The above are what could cause your engine to over heat.

So start the check from the radiator. Poor water into the radiator, wait for some minutes, look under the car and observe if water is going to leak. If there is a leak, it might be from the water pump or a leaking hose.

If water from radiator has no leak, have your radiator washed and clean the condenser has they might block air that is suppose to cool the engine.

Also, make sure your fan is blowing properly or well enough to cool the engine.

Make sure you have the above checked thoroughly as they are the major causes of problems like this.

This overheating problem could lead to a burnt gasket and this can dry the engine oil which will eventually knock the engine. So have this problem fixed to prevent further damage that will cost you more money.

Lastly, remove the hose that connects the radiator to the engine, water from the engine will come out. Pour water into the radiator, the water will flow through the hose down to the ground. Do this severally. Now connect the hose back to the engine, pour water into the radiator. Start the engine, the water in the radiator will reduce, add more water till radiator is full.

In summary, the major cause of over heating problem is from the radiator, fan, water pump, blockage in the hose, and dirt in in/on the condenser. These are area you need to concentrate on.

I forgot to mention that the acceleration meter or engine meter on the dash board shouldn't be more the 5. It should be below 5. If it is above 5, it can cause overheating. I hope you understand what I mean.....

Regards.

Is it time to junk 1999 alero 135k miles?


Where is the gallon of 50/50 going if no leaks and apparently not into the oil? Is it going out the exhaust which would be a bad Head gasket failure? So Some boil over due to overheat? Take the coolant tank cap off then start the car and see if bubbles, maybe steam eventually. If bubbles, they are probably the leaking combustion gases leaking through the Head gasket. Sometimes, retorque of the head bolts will slow the leak down. Otherwise need gasket replacement and possible head mill if it has "warped" or Junkyard heads that are good. You can confirm head gasket leak and location by a leak down test. You may be able to borrow tools from some of the auto parts stores. Have you used "leak stop" in the radiator? Sometimes that will block radiator cooling channels and cause overheating. Hopefully, that is the issue and a radiator replacement the fix. Could be a bad water pump, but if you get heat that is probably not the problem. I did that to a Chrysler many years ago and wife's car! Hope this helps.

199 oldsmobile alero temp light stays on


Well the light staying on could be a short in the wiring or a failed temp switch. And that could affect the radiator fan but I doubt it.
Have you checked the water pump and thermostat ? Is coolant flowing in the system ?

Overheating


OVERHEATING CAN BE CAUSE BY MANY THINGS LIKE FAULTY THERMOSTAT AND FAULTY RADIATOR PRESSURE CAP,TOO MUCH WATER IN COOLANT SYSTEM NEED 50 / 50 WATER AND ANTIFREEZE.LOOK FOR WATER PUMP WEEP HOLE LEAK, IF COOLANT LEAKING OUT WEEP HOLE WATER PUMP BAD NEED REPLACING.CHECK FOR LOW COOLANT LEVEL, YOUR RADIATOR OVERFLOW JUG SHOULD HAVE COOLANT AT THE FULL COLD MARK IF NOT KEEP ADDING COOLANT INTO COOLANT OVERFLOW JUG UNTIL COOLANT STOP DROPPING AND FULL COLD MARK, IF OVERFLOW COOLANT JUG WAS EMPTY RADIATOR IS LOW ON COOLANT.WHICH CAUSE AIR IN COOLANT SYSTEM KEEPING THE ENGINE COOLANT TEMPERATURE SENSOR FROM BEING SUBMERGE IN HOT COOLANT WHICH TURN ON THE COOLANT FANS.WHEN ENGINE COOLANT TEMPERATURE GET CERTAIN SET TEMPERATURE LIKE 190 DEGREES THE PCM AND COOLANT SENSOR WILL TURN ON COOLANT FANS, IF VECHICLE OVERHEATING COOLANT FANS NOT WORKING EITHER YOU HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR CHECK COOLANT FANS FUSE AND RELAYS. YOU CAN CODE SCAN CAR TO SEE IF YOU HAVE FAULTY PCM, FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR FAULTY COOLANT FAN RELAY.IF COOLANT FAN AND ENGINE COOLANT TEMPERATURE SENSOR OKAY,YOU HAVE CORRECT COOLANT LEVEL IN COOLANT SYSTEM, THERMOSTAT AND RADIATOR PRESSURE CAP BEEN REPLACED, YOU COULD HAVE BLOWN HEAD GASKET CHECK ENGINE OIL LOOKS LIKE MILK SHAKE HEAD GASKET BLOWED ALSO WHEN HEAD GASKET BLOWED YOU CAN DRIVE CAR SHORT DISTANCE START OVERHEATING AND YOU LOOSE ENGINE POWER SUSPECT BLOWED HEAD GASKET.

CAR OVERHEATING FIRST CHECK FOR LOW COOLANT IN THE RADIATOR COOLANT OVERFLOW JUG.IF COOLANT LEVEL IN OVERFLOW JUG LOW REFILL ADD COOLANT BACK TO THE FULL COLD MARK.PUT RADAITOR CAP ON COOLANT OVERFLOW JUG START ENGINE LET IT IDLE UNTIL IT OPERATING TEMPERATURE.MAKE SURE TOP RADIATOR HOSE GETTING HOT WHILE ENGINE WARM UP.IF TOP RADIATOR HOSE DONT GET HOT WHILE ENGINE IDLING YOUR THERMOSTAT COULD BE STUCK CLOSE CAUSING CAR TO OVERHEAT.IF TOP HOSE IS GETTING HOT.CHECK FOR COOLANT LEAKS CHECK TOP RADIATOR HOSE AND BOTTOM RADIATOR HOSE FOR LEAKS.CHECK FOR LEAKS AT THE RADIATOR CORES AND PLASTIC SIDE CONTAINERS.IF ALL IS GOOD ENGINE OVERHEATING WHILE IN A LONG TRAFFIC LINE, COOLANT FANS NOT COMING ON.COULD HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR BLOWN COOLING FAN FUSE OR RELAY.COULD HAVE PCM FAULT.MAKE COOLING FAN ELECTRICAL CONNECTORS AND WIRING NOT DAMAGE OR BROKEN.

I have a 1999 Oldsmobile Alero GL Sedan that is overheating. Where is the problem?


check coolant level, make sure car have half antifreeze and half water,if coolant level okay, car overheating when starting up driving is faulty thermostat and radiator cap.if car over heat while sitting in long line of traffic.your coolant temperature sensor could be faulty, or coolant fan fuse blowed or relay failed.hot wire cooling fan if it works, problem is the wiring or pcm, if every thing working okay.check engine oil if look like milk shake or you have a lot white heavy smoke coming out the exhaust, you have a blowed head gasket.
