if radiator was just put in and refilled you may need to get air out of the hose lines to get the water to circulate. some late mod cars have a vent port on the area near the t stat. or goose neck. i have been able to squeese the hose some and get it moving . check the temp of the hose after the engine is running some dont let it run too long or get too hot. you might check with manufactor service dept. for that perticular model.
Water under pressure has a higher boiling point, if the water is already hot enough to boil it will suddenly erupt when the cap is removed and pressure relieved.
blown head gasket is the usual reason for oil in coolant or radiator. sad part is if you have already replaced intake gasket, u wasted your money as you will have to replace again when you fix head gasket
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.
There are a few more things you can try, get a new radiator cap. These come in different pressure sizes as do thermostats. A thermostat comes in different temperature ranges, maybe yours is too high or low for your needs. Make sure your fan is operating properly. If all of this fails, maybe you need to have your radiator cleaned (flushed) to open clogged areas used to cool your engine cooling fluid.
sounds like your temperature sensor unit if you have already checked the thermostat and the radiator and fans are ok
If you replaced some of theses already ignore and go down the line # Not enough coolant # Water pump drivebelt defective or out of adjustment # Radiator core blocked or grille restricted # Thermostat faulty # Electric cooling fans blades broken or cracked # Radiator cap not maintaining proper pressure # Ignition timing incorrect
already have it loose
Blown fuse or wiring defect for the bulb you have already replaced. You have replaced the wrong bulb. The new bulb was defective.
Head Gasket failure or intake gasket Dexcool is the culprit, had to replace mine.
I have already replaced the radfiator,cap,thermostat and confirmed water pump works. cools fine w/o radiator cap ,pressure builds and temp. rises when cap in place.
The radiator may be plugged. Take it to a radiator shop.
This may mean there is a weak hose OR some sort of blockage in the radiator or cooling system.
The horse and buggy was replaced by the automobile. Trains already existed before the automobile.
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.
mine was the overflow tank. was cracked at the bottom so you couldn't see. it cost me 27 bucks
Low coolant? Cooling fan not working? Radiator plugged or restricted? Water pump not circulating coolant? System air bound? Defective radiator cap?
it's already a liquid at room temperature
It is already frozen because it is solid at room temperature.
It could be as simple as the radiator cap or as serious as a leaky head gasket or intake manifold gasket (GM V-6). Other possibilities: bad temperature sensor or electric fan, bugs and dirt on outside of radiator, plugged radiator, wrong coolant mix (use 50/50 water/anifreeze), plugged catalytic converter (would also affect performance). If you suspect thermostat, replace it, do not just remove it. You've already mentioned water pump and radiator.
There is no actual "radiator cap" due to the fact you have DexCool and an overflow with a pressure vent cap on it already. That is where you fill it up anyway....
It need to be replaced.
Low coolant? Wrong thermostat temperature range? Heater core plugged,restricted or airbound? Water pump not circulating coolant? Temperature control cable not adjusted properly?
check and see if ur e-fan is working The fact that it is heating up when you stop indicates that there is not enough air flow through the radiator to provide proper cooling. The likely culprits are related to the electric radiator fan. 1. Temperature sensor/switch. 2. Electrical connectors. 3. Fan motor.
the temperature already rise as you climb up in the stratosphere.
The lower radiator hose is the intake to the water pump, the coolant has already passed thru the radiator and has cooled down.
