2001 cougar overheating why?

After 5 minutes of driving Dash gauge shows max hot, radiator dash light on, no real heat from heater when turned to hot and fan on high. I get the feeling its not circulating. I have replaced the thermostat valve and still same problem. Do water pumps fail without leaking? I am used to them leaking, then replacing. Heard this year has cheapo plastic impellers that disintegrate. Is that why no leaking? not 100% on the no leaking, I will test that now. Any help is appreciated. and more recently when hot the oil light is flashing intermittently. Also, coolant reservoir is full.

    The age of your vehicle warrants water pump replacement. Don't risk a blown head gasket due to overheating. A timing belt replacement is due also. It can be done while at the front of the engine for the water pump.

On a 93 jeep Cherokee 4.0 if the catalyst converter is clog can it cause overheating?


First the dash gauge is not that accurate. Yes if you have excessive back pressure from the catalytic converter then the temperature can rise on the engine.

How does a heater cause overheating?


Here's a thought. If you use the a/c it turns on a radiator fan. If you changed it over to heat the a/c fan shuts off. So if the cooling fan was broke all a long then you wouldn't notice until you turned the heat on. How did I think this up. I owned a Ford once.

I recently replaced my thermostat on my 2001 maxima and the heater still blows cold air and the temp gage rises as if the car is overheating. Is it ok to drive the car till I can fix the problem?


when the gauges are telling you that a problem exists like over heating. Cold air may mean an air lock in the cooling system. So I consider it to be foolish to risk a motor without checking the temp gauge for correct operation for starters . After running for 10 minutes feel the top radiator hose and if it is not hot to the touch but the gauge shows hot then you have a cooling system problem that would be checked by a radiator shop.. It may just need pressure bleeding to get the air out of the system

Overheating


it could very well be a bad gauge. when it shows the engine to be overheated or at the least very hot, check the actual temp at the water outlet where the upper radiator hose attaches to the engine. use a non contact thermometer to check the temp so as not to get burned in the process. if the thermometer reads way different than the gauge, the gauge is bad.

2001 Oldsmobile Silhouette...Overheating, changed the thermostat, no signs of leaking, and the oil looks fine. At idle it takes 20 minutes to max the temperature gauge (red) and while driving it take


Usually the problem with no heat and overheating is low coolant, thermostat, or a faulty water pump impeller.
The radiator may not be full of liquid coolant, or the pump may not be moving the coolant thru the block.

On a 2000 toyota celica gt, the engine will overheat when driving only, what can cause this?


Have you checked the engine temperature when the gauge shows fully high if it is true message and not lying and the problem is the temperature gauge? Since this happened stop the car open the bonnet touch the radiator hoses and even with off running engine touch the vents of the radiator to all surface and see it the temperature is everywhere the same.

I have a 2000 Mercury Cougar and the gauge inside tells me that the engine is over heating, no heat is coming from the heater when I turn it on, the fan for the engine is running at full blast, the engine...


Hi,

The overheating and lack of cabin heat both point to a failed engine thermostat which would be stuck closed. At the warm up stage, the coolant stays in the engine block to bring the engine to efficient operating temperature, then it opens and circulates the coolant through the radiator and heat core. If the thermostat is stuck closed, the engine will overheat, and coolant will never reach the heater core, and you will not get cabin heat.

Blinking oil light at idle which goes away during driving could be a low oil level, but may also be a drop in oil pressue. You could have a clogged oil fliter (at best) pickup tube, or a failing oil pump.

Overheating? s type


Had the exact problem. Turned out that it was the thermostat that needed replacing, relatively cheap and quick by mobile mechanic. Things were fine for a year and the second time it happened I assumed it was the same problem. However, this time the thermostat was fine, wasn't sticking, and I had a slow leak in radiator, losing colant and causing engine to overheat, which paradoxically had stopped the heater working as well. Had to get new hose also by local mobile mechanic and everything seems okay again except for the intermittent "stuck in park" problem that a lot of people are also experiencing.
