SOURCE: running hot

Sounds like Clutch in your fan

The coolant level is right on, no hoses are leaking and the accessory belt is intact. You start the engine, let it idle and make a visual inspection. There's no sign of belt slippage.
If your car is like most, the cooling fan is mounted to its drive pulley via a clutch. Clutch fans operate at different speeds under different conditions to help reduce drain on the engine and to save fuel. When the engine is hot, the clutch fan runs nearly as fast as the engine. When the engine is cold, the fan runs much more slowly.
The fan clutch operation is regulated by a valve that is opened and closed by a thermostatic spring. The valve controls the flow of a viscous silicone fluid between chambers in the clutch assembly. When the engine is cold, the clutch is essentially disengaged, which is why the fan runs at its slowest compared to the engine's speed. As the engine warms up, the air flowing to the fan assembly becomes hotter. The hotter air causes the thermostatic spring to unwind and open the valve. Silicone fluid from the reservoir chamber flows into the main chamber, engaging the clutch, and the fan spins faster (though it's still slightly slower than the engine.

Hope this helps!

SOURCE: car runs hot

CHECK YOUR RELAY IN YOUR FUSE BOX UNDER THE HOOD ON THE DRIVERS SIDE INNER FENDER. THE A/C AND THE HEATER RELAY ARE SAME. CHECK AND SEE IF THE A/C REALY WORKS BY TURNING ON YOUR A/C SWITCH. THE ELECTRIC FAN SHOULD START RIGHT AWAY. OTHERWISE YOU HAVE TO WAIT TILL THE ENGINE ACHEIVES OPERATING TEMP TO KICK THE FAN ON. IF ONE DON'T WORK AND OTHER OTHER DOES... SWITCH THE RELAY AND SEE IF IT WORKS. BEEN THERE AND DONE THAT. $9.00 FOR A NEW RELAY AT CHECKER AUTO PARTS.

SOURCE: replace radiator fan motor? where 2 buy cheap online?

Well, Is the overheat due to the fan? To confirm it is, get the vehicle above 35 mph and see if it still heats up.If it does, the fan is "not guilty"If the temp drops and then goes up under35, the fan . The effect of the fan on cooking is onlyat low speed or idle. Above 35 mph, the fan is negated by the ram air across the radiator. If the temp rises above 35, then it is more than likely a thermostat. Good luck

2002 lincoln. Ls v8.. burning smell?? Tried to run hot after 15min drive at a red light but when i took off went back to half way? Keeps running hot??


Engine is too hot which is burning oil and road dirt off the engine. Sounds like a bad thermostat or a water pump problem. The radiator may be partially blocked too.

If you have a viscous fan hub then have it replaced as it is not moving the air through the radiator. Check how you placed the thermostat in the system as the bulb bit faces into the head or block so that it can sense the rising water temperature and open as required.. With not water moving through the hose I suspect that may be your problem

first check coolant level in radiator coolant level sound low.if coolant overflow jug empty.coolant sysyem low, when add coolant to coolant overflow jug coolant level should stay at full cold mark.if coolant level okay,engine overheat while sitting or moving in slow traffic either coolant fan relay or fuse could be bad.or engine coolant temperature sensor could be bad. coolant sensor turn on cooling fan at certain temperature.hot wire check to make sure cooling fan motor not bad or short in wires.if all is good have pcm check it controls fan relay to through the coolant temperature sensor signal when coolant get hot.

Hello and welcome to FixYa!
As a first course of action, I strongly suggest that you check the radiator hoses. A tiny hole in the hose can make the engine overheat. When it's overheating, the radiator fan moves on and off? If it's overheating the fan should move continuously and it should not cut off.
If that's the case, the radiator fan motor has a problem. You may want to start replacing the radiator fan motor and observe how it goes.
Hope this helps and thank you for using FixYa! Have a good one!

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.

Car overheated and lost all power. how do I get it to start?


ENGINE NOT GOING TO START IF GET TOO HOT FIRST THING I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP THEN ADD COOLANT UNTIL COOLANT LEVEL CORRECT THATS WHEN THERMOSTAT OPEN UP AND TOP HOSE HOT.CHECK FOR LEAKING RADIATOR HOSES CHECK TOP RADIATOR HOSE CHECK BOTTOM RADIATOR HOSE.CHECK FOR LEAKS AROUND THE RADIATOR LOOK DOWN BELOW COOLANTS FANS CHECK FOR LEAKS AT RADIATOR CORES OR LEAKS AT THE RADIATOR PLASTIC SIDE CONTAINERS. CHECK FOR LEAKS AT WATER PUMP WEEP HOLE AND CHECK FOR LEAKS AT THE HEATER HOSES AROUND ENGINE BLOCK TO THE HEATER CORE HOSES. THERE IS A REASON CAR OVERHEAT.IF CAR OVERHEAT WHILE DRIVING YOU HAVE FAULTY THERMOSTAT OR LEAKING OUT COOLANT OR BLOWN HEAD GASKET.IF ENGINE OVER HEAT WHILE SITTING DURING A LONG IDLING PERIOD.YOU COULD HAVE FAULTY COOLANT TEMPERATURE SENSOR OR FAULTY COOLING FAN FUSE OR RELAY.HOT WIRE COOLANT TO SEE IF IT RUNS IF NO REPLACE FAN MOTOR. IF YES FAN MOTOR COULD HAVE FAULTY WIRE OR PCM FAILURE. CHECK ENGINE CRANKCASE IF OIL LOOKS LIKE MILK SHAKE ENGINE HEAD GASKET LEAKING.

Car ran hot now it wont start at all


THE ENGINE IT WONT CRANK IF OVER HEATED CHECK COOLANT LEVEL IF LOW ADD COOLANT.REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF ENGINE STILL OVERHEAT AT A STANDSTILL OR IN A LONG LINE OF SLOW MOVING TRAFFIC.COOLANT FAN SHOULD COME ON.IF ENGINE OVERHEAT CHECK TO SEE IF COOLANT TURNS ON IF NO.CHECK COOLANT FAN FUSE AND RELAY.IFBOTH OKAY HOTWIRE COOLANT FAN TO SEE IF FAN RUNS IF NO REPLACE COOLANT FAN MOTOR. IF FAN RUNS PROBLEM COULD BE PCM OR THE COOLANT TEMPERATURE SENSOR FAULTY OR DAMAGE WIRE CONNECTOR TO COOLANT FAN.USE A CODE SCANNER TO LOOK FOR PCM OR ECT FAULTS.IF EVERY THING CHECK OUT OKAY LOOK AT ENGINE OIL DIP STICK.IF IT LOOKS LIGHT BROWN OR LIKE MILK SHAKE YOUR HEAD GASKET BLOWN.MAKE SURE YOU HAVE 50/50 ANTIFREEZE AND WATER TO ENGINE TO HELP RAISE BOILING POINT.WHEN OUTSIDE TEMPERATURES HOT.

If the fan is running backwards, you should be able to fell the "breeze" from the outside of the vehicle, near the radiator. Also, If you spray the outside of the radiator with some water, if the fan is running backwards, the water will be spraying out when the engine is running.
