Why is my '86 Nissan Maxima overheating I put in a new distributor radiator thermostate. I know the oil is fine and the water movement is ok. What else could be causing this?
Firstly you need to define overheating Is the car just running
hot or is it pushing the water out ? Ignition timing too advanced
or a lean mixture cause the engine to run hot. But if the system is
losing the water then you need to look Further. If the oil level is
ok that is fine but check the colour of the oil. If it is milky
then you might have water getting into the oil. Remove the oil
filler cap and see if that has got a milky residue on it or inside
the tappet cover. This could indicate a blown head gasket or worse
a crack somewhere in the engine. If you have access to a radiator
pressure tester check the system for water leaks, If you are losing
water through a leak this could be causing the over heating. Check
the water is being drawn from the reservoir, check the level in the
radiator as well as in the reservoir. If the radiator cap is faulty
it will lose water and also might not draw water back from the
reservoir. If you can borrow a pressure tester the remove the spark
plugs and pressurise the cooling system and let the car stand for a
while. then leaving the spark plugs out turn the engine over with
the starter and see if water comes out of the spark plug holes.
This would indicate a leak into the cylinders.
If the car is parked and when you start it it runs irracticaly and then clears it could also indicate that water is getting into the cylinders.
Your 2000 elantra has done 160k and just this week the water in the radiator has started boiling and the temperature is almost hitting red can it be the thermostate the radiator or the head gasket?
why a jeep Cherokee is over heating? Hey i don't know alot about jeeps but i know a bit about chrylslers, dodges. ok the water pump pumps water through the motor back into the radiator then back in the motor and it continues as long as the water pump is moving and isn't defected. the first thing i do when a cars over heating is check the fluid ,2.chang thermostate(its connected to the hose that…
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
No, if a fuse were to overheat it would blow. A shorted circuit can cause a fuse to blow. Yes. If the fuse for the electric cooling fan should blow, then the fan will not turn on and remove heat from the radiator at low speeds. At higher speeds, there will be enough air movement to cool the radiator. Also if your experiencing problems with your car overheating you should look into other causes, such…
