Stalling problems my car keeps over heating and stalling and i cant seem to find the problem. ive changed the water pump,fan clutch,flushed radiator taken thermostat out put new one in and driven without it and it keeps overheating and dies>< i dont know if there is some kind of heat sensor or something thats bad can anyone help me?

If your 2004 Infiniti G35 is still overheating after replacing the thermostat and cooling sensor, there may be a few other issues that could be causing the problem:

1. Radiator blockage: The radiator may be blocked or clogged, preventing the coolant from flowing through it properly. This can cause the engine to overheat. To check for a blockage, visually inspect the radiator for any obstructions or debris, and flush the radiator to clear out any buildup.
2. Water pump failure: The water pump circulates the coolant through the engine and radiator. If the water pump fails, the coolant will not circulate properly, and the engine can overheat. Check the water pump for any signs of damage or wear, and replace it if necessary.
3. Fan clutch or electric fan failure: The fan clutch or electric fan is responsible for cooling the radiator when the car is idling or driving slowly. If the fan clutch or electric fan fails, the engine can overheat when the car is not moving. Check the fan clutch or electric fan for any signs of damage or wear, and replace it if necessary.
4. Head gasket failure: If the head gasket is blown, coolant can leak into the engine cylinders, causing overheating and other problems. Check the head gasket for any signs of damage or wear, and replace it if necessary.

As for the no heat issue, it's possible that the overheating has caused damage to the heater core or other components. It's also possible that there is air trapped in the cooling system, preventing the coolant from flowing properly through the heater core. Bleeding the cooling system may resolve the issue.

fan clutch . or the electric fan . relays or fan switch.

I WOULD SUGGEST A NEW RADIATOR ..NOT PROPER FLOW WILL CAUSE THAT.MAKE SURE YOU HAVE FRESH ANTI FREEZE.

It's not possible to tell you exactly what is causing the vehicle to overheat; however, I can tell you possible causes. The engine cooling system is based on the fact that heat always travels to cold, so that if one thing is warmer than another, it will transfer its heat to the cooler thing. Engine heat is first transferred to the coolant in its water passages, the coolant carries the heat to the radiator where the heat is then transferred to the air flowing between the radiator cores and fins; the cooled coolant then returns to the engine to take away more heat. Thermostats, when they deteriorate, usually stick open from lack of spring pressure and cause the engine to run cool, so we can rule that out. You need to check for good coolant circulation by the water pump, and check the radiator and A/C condenser to make sure nothing is restricting air flow (such as bugs, leaves etc. or bent over fins), and the last, and possibly most likely source of the problem is clogged radiator cores that are not exposing the heated coolant to the air flow. The greatest tool for diagnosing cooling systems is a no touch thermometer available at many parts stores for around $30 to $50 for a decent one. If your problem is clogged radiator cores flushing seldom clears them, and few radiator shops rod out cores anymore, so the least expensive and best sure is a new radiator. One final thought, if your vehicle has a fan shroud make sure it's in place and in good shape.

You may have a blown head gasket. They can leak outside the motor, inside the cylinders (causues white smoke), or into the block causing water in the oil (light brown color and or bubbles on the dipstick) or oil in the radiator. Hopefully you have none of those, so the next step is a radiator flush as you probably have something clogging up the radiator or thermostat. You have to drain the radiator and fill with clean water. Pull out the thermostat and leave it out for the flush. There are radiator flush products that I suggest highly. Run the truck to operating temp (about 20 min) with the heat on and dump the system by removing the bottom hose hose from the radiator, after the truck cools off. With the hose still off dump water through the radiator to clean it out fully. fill with water and let it run once again to clean the block, then reinstall new thermostat and anti-freeze. This should clean out any rust and stop leak that is causing your problems.

CLUTCH ON COOLING FAN FREEWHEELING. COOLING FAN SHOULD HAVE RESISTANCE WHEN TURN WITH HAND WHEN ENGINE HOT.IF NOT FAN FREE WHEEL FAN CLUTCH NEEDS TO BE REPLACED.IF COOLING FAN OKAY.YOU COULD HAVE BLOWN HEAD GASKET.YOUR RADIATOR AND ENGINE BLOCK NEED FLUSHING OUT.CHECK WATER PUMP FOR LEAKING WEEP HOLE IF LEAKING REPLACE WATER PUMP.

Ihave a 2000 Dodge Durango i have put a new radiator and the gaskets came back good um i replaced the coolen fan also the thermostate and tested it it it came back good when i run it its fine but when i am in line its hot when i drive it cools down........

You need to make sure there is no air trapped in the system. I assume you flushed the radiator when you changed the thermostat. I also assume you installed fresh coolant mixed 50/50 antifreeze and distilled water. I also assume you installed the thermostat correctly with the spring facing the engine. Look on the upper part of the cooling system and the engine for bleeder valves (If Equipped). Now remove the radiator cap from a cold engine and make sure the radiator is totally full. Set the heater temperature control to HOT. Start the engine and look for escaping air bubbles from the radiator. Keep the coolant level full at all times. It will take awhile for the thermostat to fully open so be patient. Once you see no more escaping air bubbles install the cap. Wait about 2 minutes with the engine running and use the bleeder valves to remove any more trapped air from the system. Post back if this did not help.
