Question about 2004 Honda CR-V

1 Answer

Engine fans not working. overheating.

My fans that would cool down the engine and the fan that is for the a/c are not turning on at all. was wondering if it could be a problem with a fan relay or some type of fan sensor. Please help. very hot and traveling with an infant.

    Same problem here. Took to Honda. Cooling fan motor and condenser fan motor shot per Honda. Cost $900.00 to fix. Looks like it is not rocket science to switch out so I will find used or purchase myself and install. No way am I paying this much money for something that I can do under 100.00 bucks.

My Nissan urban keeps overheating after it got overheated what could be the cause


Cooling fans not turning on, check to make sure the cooling fans are running when overheating occurs. Not enough coolant in the cooling system, check the coolant reservoir make sure the coolant is at at the maximum level when combustion engine is completely cool,if your coolant is low add coolant to the maximum level. (1)Start combustion engine, let it warm up but not over heat. Turn off combustion engine, when it cools completely the coolant reservoirs level will be lower . Add more coolant and keep repeating (1) until the coolant level stays the same after combustion engine completely cools down.Sensor that tells the cooling fans to turn on defective. Non functioning thermostat. Broken impeller inside Water Pump. Clogged radiator. Clogged water jackets in combustion engine. Broken drive belt. Radiator has something blocking the cooling fins(possibly a plastic bag that went against the cooling fins when driving)

We borrowed our daughter's Hyundai Santa Fe to make a trip to the mountains on a 105 degree day. It was doing great on mountain highways until we stopped after about 3 hours.


May be a bad fan or thermal switch not working. The a/c condenser sits in front of the radiator. It may be that the load on the engine going up the mountain is too much for just the air blowing across it to keep it cool, and the car shuts the a/c off to try and keep engine temp down. Cruising along on level ground is enough to keep things cool. Going up the mountain means more engine heat and probably reduced speed, which reduces air flow, especially if a fan isn't working.
Let car cool off, start engine and let it warm up without driving. Monitor temp and fans. When temp gets about normal, look for fan to kick on. Then when turning on a/c, look for the other fan to kick on. Don't let engine overheat. If one or both fans don't come on, start there. Check fan motor not locked up, relay working, fuse/wiring good.

Overheating when I sit idle.


Over heating the engine is a serious concern. With the hood raised you should hear the motorized fan turn on just behind the radiator as the engine requires additional cooling.. If you look in from the rear of the radiator you should see the fan blades.

This electric powered motor operates on a thermostat and when the engine temperature rises this fan should come on. I'm assuming from your description that when driving and air is flowing through the radiator as the car travels the engine is nor overheating.

Check fan motor thermostat, check fan motor and check wiring.

Motor engine cooling fan only runs as engine temperature requires additional cooling.

Car overheated and antifreze was boiling and spewing over until engine cooled. 2004 jeep liberty 2wd. Thanks!


Need to know what caused the overheating, possible broken serpentine belt, thermostat, water pump, radiator, fan clutch, cooling fan motor. After motor has cooled down fill radiator with water till full, look make sure serpentine belt not broke, start engine run about 5 minutes, turn off, let sit 3 minutes, start engine look at temperture gauge is it over half way of gauge, Do you have a fan blade driven by water pump or electric fans?

I have 2003 grand cherokee with 140000 miles that overheats at idle. as soon as i start moving again, the temp goes back to normal.


You have two fan's on your truck, 1 is a fan clutch runs with the drive belt, 2 elec fan motor, with test light and engine running at normal temp, just a little bit above 1/2 way on your temp gauge check voltage at elec. cooling fan harness if you have voltage at one of the two wire's and fan don't turn on, bad cooling fan motor, on the fan clutch after you check voltage at elec. fan motor turn engine off, with your hand spin drive belt fan if it spin's freely bad fan clutch, replace it.Also check cooling level.Hope this was very helpful

Fans not working it was overheating i replaced temperature sensor and it cooled the motor down but i had to connect the fans to a fuse to the motor for them to come on when car turns on


Your tempature sensor was probably the reason why your vehicle overheated but as far as hooking the fan to fuse to the motor isnt a bad thing its the same as installing a after market electric fan it will just keep your engine cooler.

94 honda is overheating


I dont think the transmission has anything to do with your overheating problem...Check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem..Did you ever replace the thermostat? If it is stuck then it would also cause overheating...Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.
