If nothing works then its time to see if the radiator fan motor is ok and is properly spinning.
. Nothing stays forever so it is normal to be worn out. When I bought this car for my brother it came with some codesP0302 - misfire cylinder 2P03. The Compressor moves air to the condenser from the radiator.
It idles rough when cold and the radiator fan doesnt kick on when its supposed to. RADIATOR CAP A LITTLE AT A TIME UNTIL ALL PRESSURE RELIEVEDREMOVE RADIATOR CAPADD MORE COOLANTCRANK CAR AGAIN LET IDLE UNTIL TOP RADIATOR GET HOTKEEP EYE ON TEMPGAUGE. The radiator fans do not work at any time even when applying a voltage to them from a separate source.
A caveat cooling fans can work intermittently relays usually either work or they dont. Radiator fan testing points. Start by unplugging the wires.
2 check the 2 wires from the controller to the fan. Hey guys here we bring you another fix. It Exeed Radiator cooling fan be low on refrigerant or a bad relay a sensor an ambient temperature switch or the AC pressure transducer.
Replaced the radiator fan assembly but they still wont spin. The computer will usually compensate for this quickly via opening the air bypass valve more. A normal relays resistance will read between 40 to 80 ohms.
My cooling fan is not working properly while AC running and AC is Exeed Radiator cooling fan cool. 2005 radiator fan not working temperature gauge going up when engine idle I recently had leakage in water pump so I - Volkswagen 2005 Jetta question. With AC turned on there should be 12V PWM signal across the wires.
Im putting together a video of my 1991 SC 5-Speed starting up and running. The coolant level should always. Im hoping someone out there with more Super Coupe experience can.
One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. You can also measure the relay coils resistance. My car has 2 main problems Im trying to solve.
If the cooling fan doesnt engage there may be something wrong with the cooling fan relay. Dont need to start engine. It idles rough when cold and the radiator fan doesnt kick on when its supposed to.
No radiator fan operation would explain why your AC is not working right at idle condenser coils too hot with lack of air flow and is OK if the vehicle is moving at speed. The radiator fan can be damaged by excessive use or become aged. No the AC will turn the radiator fan on to pull air across the condensor.
The radiator hose is very hot and there is a lot of pressure built up in the hose and antifreeze starts to seep out of the top of radiator but i cant pin point were it is coming from. If the engine is heating but the fan isnt kicking in check the fan wires. A car air conditioning system takes energy from the engine but when your car engine is overheated the car AC system cant get the right amount of energy as is needed and this is another reason.
Radiator fan not working After car is warmed up and at idle the fans do not come on. Unplug the connector that feeds power to the radiator fan and connect it. You can check this by plugging a different power source into your radiator fan.
It over heats when its at an idle. If it is not replace it immediately and this should take care of the problem. There are usually two marks on it a minimum and maximum level mark.
If you notice that your engine is running at higher temperatures than normal. To check the level look for the coolant expansion tank in the engine bay. The inoperative cooling fans are causing the cooling system heat to rise.
My car has an automatic transmission. These are the common cause of radiator fan not working. Try to measure the voltage in AC mode not DC.
This is a 2 in 1 special. If the cars engine is already overheated then the radiator and condenser fan cant work properly. Fuse connects the fan with the cars electronic system.
Best to measure this with an oscilloscope. Why is the radiator fan not working. 3 If all the above signals and wires are good and fan not running then its a bad fan.
Had the AC system checked. Via a relay to high speed. Measuring the Relay Coils Resistance.
Up to 8 cash back Usually a faulty cooling fan relay will produce a few symptoms that can alert the driver that service may be required. On July 26 2016. Best to measure this with an oscilloscope.
Up to 8 cash back It over heats when its at an idle. Check the fuses for the electric radiator fans. Get a fuse kit here with multiple sizes for multiple quick repairs.
Check the engine coolant level. Make sure the fuse for the radiator fan is intact. If your engine coolants too low it means that the cooling fan will have to work harder to keep the engine at a normal temperature.
Radiator fans not working and car overheats while idle asked by Seth C. If you have a belt-driven fan and your engine overheats at idle but not at highway speeds AND your coolant level is at the proper level you may have a faulty radiator fan clutch.
