I took out the thermostat, filled coolant level to upmost, my car still overheats, it doesnt leak ne where.How can I tell if the water pump is workin?
if you can look down inside the radiator watch the water see how it moves.... check you hoses if any of them are soft or fat looking.... and it dont have to leak to be bad but in most cases it leaks..... most of the time when a car over heats its a flow thing
water pumps are generally built with a weephole ( a spot where if coolant enters the internals in the pump it will leak out externally) it could be a blockage in the system somwhere, radiator, engine block, or heater core
by the sound of it, no the water pump is not working. i had the same problem with my car. it started over heating, so i replaced the radiator cap, still over heated. replaced the thermostat, and still over heated. finally i took off the water pump, to find that the fins that are inside the punp, ( that move the water around) had all corroded away. i replaced the water pump with a new one, and its been running great ever since.
Overheating normally would require a failed water pump. Some liquid leaking out of the weep hole normally just indicates that the pump is going to fail. Does the water pump make a clicking sound? An abnormal pump sound also is an indicator of a pump that is starting to fail. Verify that the coolant is full. If full, check the fan. If the fan is not turning on between 185 to 225, the temperature sensor may be bad. Also verify that the thermostat is installed in the correct direction. If installed backwards, the engine will overheat quickly. (This is an easy mistake.) Good luck!
check your fan thermostat
