Question about 2000 Nissan Frontier
I have replaced radiator, water pump and several thermostats. Unable to stop my truck from heating up.
Have you checked the operation of the electric fans? If they are not turning on at the right time, the engine will overheat.

It could be just air in the system, or it could be the heater matrix just by your feet, fitted central dash, check to see if the two water pipes that go into the car from the engine compartment are hot if there is only one that is then thats your problem, but if they are both cold the problem is more to do with where the water is coming from, please let me know how you get on

Testimonial: "Great tips, pointed me in the right direction."
Simple thing to test first would be to pressure check the radiator cap. Next would be to check for combustion gases in the radiator indicating a leaking head gasket. It is an aluminum head and iron block engine and there is a possibility that antifreeze anti corrosionpackage runs out due to over age then fails due to too long in the engine it results in galvanic corrosion at the head gasket-commonly resulting in a failed head gasket. There are other engines that are vastly more prone to this than the maxima engine. If there is a leaking head gasket the gases could rise to the top of the system and block the water flow into the heater. Listen for gurgling sound in the heater.

when you changed the therm you let air into the system and it will usually cause a air bubble in the heater core you probally should try to burp the system there is usually a plug or a relief valve check with your dealer fro instructions on how to burp the air out of the system try that first befor4e trying to replace the heater core

Hello, im sure being a mechanic you know to check the weep whole on the water pump for leakage. The thermostat is a possibility, could be stuck closed. The impellers on the water pump begining to fail. Hope this was helpful
