What would cause a 94 tempo to overheat replaced radiator and thermostat already?

Since you have replaced these two parts, have you checked the water pump ? With age, the impeller on the pump or bushings become used enough to reduce the flow of coolant quite a bit. This will cause over heating due to lack of circulation. Also did you flush the system to make sure that there are no blockages ? And, check the upper and lower hose to make sure they do not collapse.

Why is my Nissan maxima overheating already replaced thermostat?
Even though you have already replaced the thermostat, there are other issues that can cause your Nissan Maxima to overheat. Your fan may be stuck and not operating as it should.
My temp gaugebmw 318 e46 rises for no reason can anyone help already replaced the thermo sensor?
Does that mean that you replaced the thermostat AND the sensor? If not, you really need to replace the thermostat. A sticking thermostat can cause temperature swings and potentially overheat the engine. BTW, BMW engines tend to have serious problems when they overheat. Don't let it overheat or you might be buying a new engine.
Why would a car blow cold air and overheat at the same time if the thermostat has already been replaced and there is sufficient coolant?
Could be a head gasket or a warped or cracked Cylinder head.
What else do you check after blocked hoses thermostat fans and radiator when your 1990 Honda Civic continues to overheat?
The IMPELLER on the water pump.The MIXTURE of Anti-Freeze to Water mixture.Blown head gasket.Correct TIMING.the FLOW on the Radiator that U already checked...
Why would the radiator fan continue to run after the engine stops after the thermostat was replaced on a 2002 Nissan Altima?
Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.
Why would a 92 Eclipse push water back through the thermostat housing and overheat?
The thermostat is most likely stuck in the closed position and needs to be replaced. The closed thermostat does not allow the coolant to circulate through the radiator, thus overheating the engine. The reason for water being pushed through the thermostat housing is because the water pump is spinning and there is no place for the coolant to go, therefore, it is leaking out through the housing gasket which is probably already blown (need to replace it when you replace the thermostat.
Why does my 97 Subaru overheat but when you accelerate it cools off I already changed the thermostat 3 times and It has a brand new cooling system.?
has the water pump been changed. is the fan working correctly. sounds to me you are not getting enough cooler air through radiator. check the operation of the fan and that the radiator fins are not full of dirt and leaves
What could be wrong if your car is overheating you have already checked water pump and thermostat and there are no leaks anywhere?
The radiator may be plugged. Take it to a radiator shop.
The hose on your radiator is swelling up but you already took out the thermostat?
This may mean there is a weak hose OR some sort of blockage in the radiator or cooling system.
What is a reasonable life expectancy for a water pump on a Montero Sport with 3.0 engine I see no leakage but temp gauge climbs now on a hot day with AC on. Thermostat already replaced.?
Start by replacing the radiator cap, it is more dangerous than the thermostat because it loses pressure.
If a 1986 300Ci straight 6 is overheating And you already changed the Radiator what is next?
water pump. thermostat.
If you already replaced the radiator fan but it is not switching on does that mean the thermostat is the next place to look?
if your thermostat was bad your engine will over heat but it has nothing to do with the fan,fans are driven by a diffrent mechanism. try checking your thermostatic switch/ heat sensitive switch or sensor, located somewhere in the cooling system(radiator,engine block or thermostat housing) which is the one that tells the fan when to come on.(only electric fans)it may be faulty wiring
