A '99 should be extended life coolant. brand doesn't matter so much as making sure you DO NOT mix with ethylene glycol (green) coolant. fill to the level as marked on the overflow reservoir, but more importantly, you should have the leak(s) located and addressed... it went somewhere...

How do I remove radiator?

Hi, Sorry I have to say that if you need to ask how to replace a radiator, you will need help from someone who knows how. It's not a trivial job. Having said that, the problem may be relatively simple. It's not uncommon for the radiator thermostat to cause overheating symptoms and or produce symptoms of leaking. Plus it's a lot easier to replace than the radiator. What you could do is take the thermostat out just for testing reasons. A lot of people do that and then never put it back. But your should have a thermostat because your car will take a lot longer to heat up to normal temperature without it and also likely cost more in fuel to run. Okay, to change the thermostat: Make sure the car engine is cool to cold. Don't try to remove it after driving. It can be dangerous. There is a danger of getting burnt by boiling hot water if you ignore this advice. Once you are sure the car is cold, take the radiator cap off. Check the coolant levels while you are looking. Partially drain coolant. Remove the hose to the manifold, remove the thermostat. Also check out a few sites that show information on your brand and model of car. EG: - This site shows details on how to do it. Rgds, Dave.

Little heat coming out of vents on my 1999 cutlass

You may have air in your lines. Open your radiator, then start your car and let it run for a while, add coolant when it drops low. There are bleeder screws on your car for your coolant. When the car is at normal operating tempature open your bleeders untill coolant starts to come out. On my 3.8L V6 you just have to follow the top coolant hose to where it connects to the intake. You will most likely need a flat head screw driver to open it. Then as the coolant drops again keep adding coolant. You may want to have a drop pan and tarp under the car, coolant will pour out of the radiator at times. Not a ton, but don't be concerned. This may take up to 20-30 minutes to complete. If you open the bleeder and coolant comes out right away it would lead away from air in your lines. Last thing have your heat on in the car the whole time. Hope this helps.

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 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.

My 1997 Oldsmobile Cutlass is overheating.. I have replaced the water pump, Thermostat, and had the coolant flushed.. still overheating... What could it be?

Have you had the radiator cap pressure checked? Small part...big function...Are you sure the thermostat is in the open position when installed? Hope this helps.

My car is overheating.i changed the thermostat,radiator and coolant sensor.

What is the indication that the car is overheating, is it the temp gauge or is the cooling system overflowing? A high tech scan tool can read the actual engine temperature, maybe you gauge is faulty.
If car is actually overheating, other areas to check or suspect is the water pump, hoses or there maybe some obstruction in the engine itself.

My 1999 alero is overheating and engine coolant is leaking

hi, i dont know about the dipstick, but your overheating problem is most likely to be the thermostat...sounds like its stuck in the closed position,not allowing colder water to circulate, hence the overheating.......needs changing
