The problem is likely in your heater case doors, not the core itself. These doors are either vacuum operated or small motor operated.
Get the car warmed up, then feel both heater hoses. Both should be hot, meaning coolant is circulating. If only one is hot, the other cold, then you have a circulation problem.
are the upper and lower radiator hoses hot when car overheats? if so check for a clogged radiator or weak water pump. if one hose is hot and the other is cold or much cooler then replace the thermostat.
It you're losing coolant and it overheats, that's a sign of a bad head gasket. Get that checked before you spend any more time or money on anything else
Engine coolant temp sensor should be on the drivers side of the
engine block. Follow your top radiator hose from the radiator to the
engine block. near that you should see a sensor (it has a clip on it
where the wires attach).
you could have an air pocket in the cooling system that has to be burped. With a cold engine, park uphill and leave the radiator cap loose. Fill radiator and coolant reservoir. Start engine with cap loose and run at 1500 rpm until temp gauge reads normal. Feel if top radiator return hose from engine to radiator is hot. If yes, coolant is flowing and thermostat is open. If cold, thermostat is not staying closed until engine is hot.
My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!
does the car overheat at idle or travelling down the road? if the thermostat was not changed, thats first step. checking it is replacing it. possibly air-bound. then i would suspect a headgasket problem.
thank you very much. now coolant is not over flowing. and that is good news. i will try to get more troubleshooting. how to find that solenoind.
