could have and air lock in the system
im having the same problem with my 1994 I've replaced the heater core,thermostat,radiator,i checked the coolant, and it's not over heating or nothing and still no heat lol
Have you checked for Carbon Monoxide in the radiator coolant? If it's there, you have a leaking headgasket. The problem is, if your Nissan overheated for any reason, the head can warp and result in a leaky headgasket. Once that happens you'll never be able to keep it from overheating.
Your radiator may not be heating up properly due to issues such as air trapped in the system, a malfunctioning thermostat, low water levels, or a faulty water pump. It is important to have a professional inspect and diagnose the problem to ensure proper heating in your radiator.
Hi have you checked the radiator for blockage if it is blowing water back out the radiator this could be the problem.
i have problem my dodge intrepid 97 v6 3.5 overheating just in the machine not a radiator system
check the thermostat or the fan motor could be the problem or a leak in radiator. just a thought
97 Grand AM Try replacing the radiator.
check the heater core stopped up radiator
with my 95 mx3 i was having the same problem all i did was adjusted the angle of the radiator and the over heating problem stopped id try that
have u checked the coils i had the same problem after i changed mine the kia was fine
I would have your alternator checked as I had a similar problem and changed mine. Worked fine after that.
have you checked ur thermoswitch or the relay Simply check if the fan units are running when the engine is hot. Easiest to do when the hood is up. Are you losing coolant from the expansion tank, this could be a sign of failed Head Gasket.
