SOURCE: 98 dodge dakota slt 318. no heat, low operating temp

First thing first, turn off the engine wait for 15 - 20 mints, open the radiator cap and fill it up to the top then start the engine and see if it needs more water adn add as needed, then wait till you ca see the water circulating in the radiator now instead of corculating if it starts boiling out shut the engine replace the thermostat and do the whole thing again.

unless there is water in the engine the gauge will not be able to show the actual temp of the engine, so always malke sure you have water / antifreeze

the fan motor could just be bad, you can test this by removing the fan and connecting a wire to each terminal and to a battery. the wires hooked up one way will spin the fan and the other way will spin the fan backwards so you cant hook it up wrong. I hope that helps you out!

1994 buick skylark overheating why


Check the coolant level.
The radiator must be full, coolant should be mix of 50/50.
If it is full, and stays full when overheating, the most common cause is a defective cooling fan.
One of your electric radiator fans is for your A/C and one is for the radiator cooling
Any time the temperature gauge/ or red light comes on, that fan should be running.
Raise the hood and look the next time it overheats, and if no fans are running, you need get it fixed quick, lest you blow a head gasket.
The problem could be either the electric fan motor, or the sensor switch that screws into the engine block.
If the coolant stays full, and the fans are running, you may have a stuck or closed thermostat.
God bless your efforts.

Mini Cooper temperature gauge goes to red zone when idle


check coolant level could be too low allowing air in the cooling system causing air pocket in engine around the engine coolant sensor.coolant sensor needs to be in hot coolant so it will cause the cooling fan to come on at a set temperature.make sure coolant correct level and the coolant level in the cooling overflow jug should be at full cold mark.the cooling overflow jug should never be empty,if you see empty cooling overflow jug air got in the cooling system so make sure when engine cold every time raise hood make sure cooling overflow jug coolant level at full cold mark.if jug stay empty you have cooling leak.so replace radiator cap,if coolant level all good,i would replace the engine coolant temperature and thermostat.when your car come to a long stop or driving along long line of slow moving traffic the engine coolant blower motor should running if not have vechicle code scan for faulty coolant fan motor control module.or ecm problems.

Engine overheating i have replaced the radiator has plenty of water


replace thermostat.then bleed coolant system, this is how you do it.fill the cooling coolant system with 50 / 50 dexcool and water to raise boiling point,straight water will evaporate boil away cause engine to overheat catch fire thats why you need 50 / 50 mixture antifreeze and water.to bleed coolant system first fill coolant system until coolant stay at the full cold mark on the the coolant overflow jug,then you start engine allow it to idle,place the heater and ac control in any ac setting except max and the temperature control to the highest setting,run engine until lower hose to water pump is hot. with the engine hot run the engine speed up to 3000 rpm and allow it return to idle, repeat this 5 times. slowly open the bleed valve on the thermostat housing or look for bleed valve at the water pump heater hose.open bleed valve for 15 seconds to expel any trapped air.then top off the coolant as necessary,and when top radiator hose hot thermostat open up.keep adding cooling to overflow until coolant level stop at full cold mark dont over fill coolant.if engine seem like overheating while looking at cooling gauge turn off engine wait a while until cool off add more coolant until coolant level stay stable and dont drop any.when open radiator overflow cap use large rag over the radiator cap to keep from getting scald open radiator cap a little at a time but dont open radiator cap until engine cool down first.replace the radiator overflow cap, thermostat,and engine coolant temperature sensor and check the cooling fans fuses and relays see what happens.

IT KEEPS OVERHEATING


REPLACE THE THERMOSTAT AND RADIATOR PRESSURE CAP.IF COOLANT LOW, ADD MORE COOLANT THROUGH COOLANT OVERFLOW UNTIL COOLANT LEVEL IN THE COOLANT OVERFLOW STAY AT FULL COLD MARK.REASON POUR COOLANT THROUGH COOLANT OVERFLOW MOST GM CARS DONT HAVE RADIATOR CAP.WHEN YOU GET COOLANT LEVEL OKAY, CRANK CAR LET IT IDLE UNTIL ENGINE GET HOT BUILD UP PRESSURE THEN TURN OFF CAR.CHECK FOR COOLANTS LEAKS AT THE RADIATOR HOSES,CHECK FOR LEAKS AT THE RADIATOR, CHECK FOR LEAKS AT WATER PUMP WEEP HOLE IF YOU SEE COOLANT LEAKING FROM WEEP HOLE REPLACE WATER PUMP. IF CAR OVERHEATING WHILE IDLING YOUR COOLING FANS NOT WORKING CHECK COOLING FANS FUSE AND RELAYS.IF FUSE AND RELAYS OKAY THE ENGINECOOLANT TEMPERATURE SENSOR BAD.

SOUND LIKE ENGINE OVERHEATING,CHECK COOLANT LEVEL MAKE SURE YOUR RADIATOR FULL OF ANTIFREEZE.IF YOUR COOLANT OVERFLOW JUG IS EMPTY COOLANT LEVEL IS LOW.NEED ADD MORE COOLANT TO OVERFLOW UNTIL COOLANT STAY AT FULL COLD MARK. DONT OVER FILL COOLANT OVER FLOW JUG.IF COOLANT OKAY ENGINE OVERHEATING REPLACE THERMOSTAT.MAKE SURE ENGINE COOLING FAN IS WORKING IF YOU COME TO A STOP CAR SITS FOR A LITTLE WHILE START OVERHEATING THE COOLING FAN NOT TURNING ON , BECAUSE COOLANT FAN FUSE BLOWED OR YOU HAVE BAD RELAY,THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.IF YOU HAVE THE CLUTCH TYPE COOLING FAN, MAKE SURE WHEN TURNING CLUTCH FAN WITH HAND COOLING FAN SHOULD HAVE RESISTANCE WHEN HOT.IF CLUTCH FAN FEEL WOBBLY AND LOOSE REPLACE IT.TAKE VECHICLE TO AUTO ZONE OR ADVANCE AUTO PARTS OR ANY AUTO PARTS STORES THEY WILL CODE SCAN CAR FREE AND GIVE YOU THE CHECK ENGINE LIGHT TROUBLE CODE TO SEE WHAT CAUSING CHECK ENGINE LIGHT TO TURN ON.

My car is running hot, and I dont know what to do.


{: ) You didn't mention the model of your vehicle. Anyway, we can try some cooling system basics.
You can begin checking with the things that keep the engine cool.
1. The coolant. Are you using plain H2O? Check the coolant level and also look for signs of coolant leaks.
2. The radiator. Check for obstructions at the radiator area like plastics and debris. Foreign materials could have accumulated on the radiator fins. Clean if necessary.
3. Cooling fans. Check for damages or cracks. Is it operating at expected speeds when it should be? For example, at 106deg it works on low speed, at 110deg it should spin high speed. If it stays on low speed all time or none at all, check the fan relays and fuses.
4. Water pump. Is it noisy? Have you checked the belt? It may be old and cracked, better replace it. If a thermostat is stuck, coolant won't circulate and engine will heat up fast to undesirable levels.

How about the other things that add more heat to the engine?
1. Engine pulleys getting stuck. A/C, water pump, steering pump, alternator, idler and tensioner pulleys.
2. A/C system high pressures on the condenser.
3. Oil level and pressure low
4. Poor engine emissions performance. Engine timing, tune-up, clogged exhaust pipes
5. Stuck brakes or bearings
6. High ambient temperatures
7. Poor wheel alignment, low tire pressures

I hope I didn't miss out on any other more important things to include. Wish you goodluck.

Vw jetta iv, temperature alarm sounds and flash with no aparent reason. temperature dial indiator is ok.


I WOULD CHECK BOTH RADIATOR HOSES TO MAKE SURE THEY ARE HOT. THERMOSTAT COULD BE STICKING SLIGHTLY CLOSED.CHECK COOLANT LEVEL MAKE SURE COOLANT NOT LOW.IF COOLING NOT BOILING OUT OF THE EXPANSION TANK. I WOULD HAVE CAR HOOKED UP TO A DIAGNOTIC SCANNER AND CHECK COOLANT TEMPERATURE SEE IF TEMP. OVER 230 DEGREES IF SO RADIATOR COOLING FANS NOT WORKING.COOLANT THERMO SWITCH BAD BOTH FANS SHOULD BE RUNNING AT LOW SPEED.IF ALL LOOKS GOOD YOU COULD HAVE FAULTY LOW COOLANT SENSOR IN EXPANSION TANK.MAKE SURE COOLANT IS IN THE EXPANSION TANK BECAUSE COOLANT LEVEL COULD BE LOW.ADD COOLANT IN THE EXPANSION TANK UNTIL YOU AT MAX LEVEL LINE ON THE EXPANSION TANK.DONT OVER FILL THE EXPANSION KEEP ADDING COOLANT UNTIL COOLANT LEVEL STAYS AT THE MAX LEVEL LINE ON THE EXPANSION TANK.

bad low coolant switch or still low on coolant.

Engine Cooling The cooling system components are the:
  • engine coolant temperature sensor (ECT sensor) (12A648)
  • radiator (8005)
  • degas bottle (8A080)
  • radiator draincock (8115)
  • water pump (8501)
  • water temperature indicator sender unit (10884)
  • water thermostat (8575)
  • dual speed fan motor assembly
The water pump circulates the coolant.
The water thermostat:
  • controls the engine coolant temperature.
  • allows quicker engine warm-up.
The degas bottle:
  • provides a location for fill.
  • contains coolant expansion and system pressurization.
  • provides air separation during operation.
  • replenishes the engine coolant to the system.
The fan motor (8C607):
  • operates only when the ignition switch is in the RUN position.
  • will not operate with the switch in the OFF position.
The engine coolant flows:
  • from the lower radiator hose (8286) to the water pump.
  • from the water pump to the engine block and the cylinder heads.
A closed water thermostat returns the engine coolant to the water pump; an open water thermostat allows the engine coolant to flow to the radiator.
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle.
When adding engine coolant, use a 50/50 mixture of clean, drinkable water and engine coolant.
To maintain the integrity of the coolant and the cooling system:

Overheats on hwy. Radiator fan does not engage after overheating


fan does not generally come on till you reach about 210f. second fay comes on when ac compressor is on. Allowing for gauge inaccuracy this does not sound like a problem. Have you checked for coolant loss inside or outside the engine? If coolant is low, it may not be reaching the sensor unless you make pump run faster. Those engines are known for head and intake gasket problems, which may be the underlying cause of what you described. A partilally obstructed radiator can give some of the symptoms but I don't thind that is it.
