Over heating problem.

[s13dude.]

So my car kept overheating and i took it to a mechanic he hooked a device that tells u whats wrong with your car and it came out to be i had been leaking from my water pump so i replaced it with a new one and the leak stopped but it still overheats what else could be the problem????

[moso]

thermostat, radiator, water pump. those three items about wrap up the cooling system

well new water pump, and the radiator was replaced a couple months back, oh yeah my radiator cap is old could that be a problem aswell??my neighbor know a thing or two bout nissan and he said try getting a new radiator cap and if it still overheats then it shud be the thermostat....

since you just had your water pump replaced, there's a chance that the system wasn't bled correctly and there's air in the system. Also, when does it overheat? At a stoplight? or while your coasting? the fan clutch could be bad. or a thermostat , depending on your answer.

Could also be the head gasket. If you take the radiator cap off while it is running, and have a steady stream of air bubble, that would be the problem.

Heads Gasket prob usually leads to smoking. I agree that your system might not have been bled properly. Thermostat is also a very common prob. When does she overheat. Stopped or while cruising. Have you ever put STOP LEAK in your radiator? (That s*** should be illegal)

When im coasting, i was told my thermostat was the problem, So ima go ahead and replace that and hopefully that solves my problem thanx guys! for the feedback.
