HELP ASAP , OVER HEATING


you need to have the system check for pressure-it should be about 17psi -if it goes higher you have a blown head gasket which is blowing the coolant out of the system-or you might just have a radiator cap which is failing to hold pressure-up to 17psi- also youmay not be getting all the air out of the system and have an air pocket which will get super hot and steam the antifreeze- have the system vacummed down and the antifreeze will be sucked back into the system eleminating the air pockets-so you have a few things to look here-Ihopr this helps-Denny

My guess is that your electric fan is NOT operating at all. Under normal conditions, just going down the highway, your cooling system will function just fine without a fan running. The air flow through the radiator is adequate to keep things cool. However, when you stop, you quickly get into an "overheat" situation. Actually, you should be able to hear your fan begin operating when your engine temperature starts climbing or your air conditioner requires the fan to do its thing. Note: If you've ever severely overheated your engine, your problems may be worse than just a fan not running, but you really do need to confirm whether your fan is operating correctly, or not. Another note: I had a vehicle with a tendency to overheat when stopped. It turned out to be a faulty (leaking) pressure cap on the cooling system.

BMW 328i 1996 Heater not blowing hot air How do I flush the heater core


You cant just flush the core, youre going to have to flush the whole system. There is a kit but i recommend going to a lube shop. Another cause could be the radiator cap.

I have a bmw 328i 1996 and it overheats but my oil light comes on and soon after the car starts to try and cut of i changed spark plugs and new oil change........ wats wrong with my baby


Most likely a bad Thermostat or Water Pump. Replace the Thermostat, the cheapest part, and if it still overheats replace the water pump.

I have a 2000 BMW 328i the tank along side the radiator has cracked and there is oil in the radiator fluid. Could this be from the cracked tank?


Likely the cause is the opposite of what you are thinking. Oil in the radiator (engine oil) is caused by a blown cylinder head gasket. When that gasket fails it can overpressurize the cooling system by permitting compression from the pistons to enter. (cooling system pressure rarely is above 20psi...compression pressure is more like 150psi. That will cause the radiator tank to burst)

1996 Acura 3.2TL Overheating Problem...


From your description of symtoms it sounds like you have a bad water pump. If the coolant is not circulating properly you will have a heating problem. Sometimes even a new thermostat can stick and cause the engine to overheat. I have seen them fail in as little as a week after they were installed.

Just because it was not hot to the touch, does not mean it is not a coolant loss problem----if the coolant is so low, there may not be enough to make the radiator hot (though usually the steam in the system will).
...a stuck thermostat can also let the engine overheat while the radiator remains cool (the fluid only circulates within the engine and is stopped from getting to the radiator.
...likewise a hose could have burst below and let the coolant out, over heating the engine, and the steam going out the ruptured/popped off hose; would look underneath..
...when cool, check the level in the radiator (likely empty),
...and less than a mile away, may not have ever heated the radiator, though usually only a mile to heat up the coolant
...of course there is always sabotage
...and water pump failure, (so no water circulated) causing overheating and no radiator heat, and possibly enough pressure to blow off a hose, but usually the radiator cap relief spring would allow pressure to escape (and that steam would heat up the radiator on the way---but if only steam in the radiator, it would cool off quickly after venting, because no more water in the radiator to hold the heat. all depending on climate,temp and further details , symptoms..
hope helps..

Engine overheats, especially on the highway. Did one of those autoparts flush and it didn't work. Changed the water pump and the thermostat before the flushing. No milky color on the oil, no white steam...


Make sure the electric radiator fan is coming on watch it while it's running for about ten minutes if it doeasn't come on in that time replace the fan relay or fan itself if the relay doesn't fix the problem.
