Should I see both A/C fan and Radiator fan spining when A/C.
The clutch also limits how fast the fan can spin and only turns the fan at a fraction of the water pump speed, depending on engine speed and temperature. Select a Clutch Fan for: Stock or mildly modified engines; Best overall cooling ability; Applications up to 6,000 rpm; Flex fans don’t use a clutch and therefore operate at 100 percent of. Once it reaches a 200 plus or minus depending on vehicle the fan will kick on. Many single electric fan systems normally have a high and low. A/C on triggers a high fan or hard running engine can do the same. Normally operation with A/C off fan will cycle in low as required by the engine temp spec requirements.
AC Fan Motor Not Spinning: What's the Problem? | HVAC System.
It should draw air through the radiator from front to back. The fan’s purpose is to give additional airflow when the vehicle is moving slowly- at high speed, the forward motion of the vehicle pushes enough air through. So a fan mounted in front of the radiator will be a “pusher” fan: blowing air over the radiator with a positive pressure. A “puller” fan behind the radiator instead sucks air. A fan clutch should not freely spin unless it is at its operating temperature. Generally, a faulty fan clutch should spin well around or more than five times a day the vehicle has not been used if you have tried to spin with the maximum force possible. A properly functioning fan will put up resistance as you try to forcefully spin it..
Which Way Should a Radiator Fan Spin? - HAOHONGWEI Machinery.
Which way should a fan spin? Single phase fans spin clockwise, with the observer facing the "front" of the fan where the fan blade (s) is mounted (or where the shaft of the motor sticks out for the blade to mount on). This is a convention used by motor manufacturers worldwide. Bob Kennett. If they don't come on after about a minute or so then you likely have a problem. The ML has a much larger mechanical cooling fan behind the rad which handles most regular cooling duties.

The Fan ECT switch in the lower radiator passes power when cold and blocks power when above 195degF (approx.) Just in front of the battery on the drivers side of the rad you will see 2 connectors. One is for the fan motor, the other is for the Fan ECT switch/. Disconnect the Fan ECT connectors. Fan spins excessively when engine is stopped (three or more times when hot engine is shut off). Poor A/C performance at idle or low vehicle speeds. Fan speed does not increase when engine is hot. Fan speed does not increase until engine is excessively hot. Fan blade tip moves more than 1/4-inch front to back.

And as you noted, there is a tie-in with the AC system that should at least bring the fans to low speed even if the water temp is low.
Should a Fan Clutch Spin Freely When Cold or Hot? (Answered).
163 Posts. #10 · Aug 29, 2016. jdeanwaite said: Loud being that the fan clutch is always engaged and therefore the airflow is loud. It is a known problem and does decrease HP and mileage. My dad also has a Frontier around the same year and it is much quieter as the fan is able to disengage when it isn't hot out. Originally posted by coupe. I dont believe it, my fans are turning turning clockwise, when I stand in front of the car..This may explain the cooling problem. Check how the blades are oriented. If you reverse the pitch of the blades, then the fan can be turning clockwise and still be pulling air from the front. Aaron. You can test the electrical radiator fans by taking a wire from the car battery, unplug the radiator fan connector, and put 12v+ and ground into the connector. This is the fastest and easiest way to test your radiator fans. 6. Faulty Fan Relay Because the radiator fan is often drawing so much power, there is often a relay powering the coolant fan.

The easiest way to check on the AC fan motor is to switch your thermostat from "Auto" or "Cool" to "Fan" mode. When "Fan" mode is turned on, the AC fan should be running continuously, even when the condenser coils are off. This is intended to create airflow in your house even when the temperature is already at the correct level. 1,096 Posts. #4 · Feb 23, 2016. most atv fans are "pull" type fans that pull air through the front of the bike over the motor. just about every radiator cooled and oil cooled honda atv im aware of pulls air through the radiator/cooler (fan is mounted between the engine and radiator/cooler) to pull air over the cooling fins of the head/cylinder.

Radiator Fan Is Not Working? (7 Causes & How to Fix).
Auxillary fans are the 2 electric fans in front of the radiator. actually the driver side fan is electric while the passenger side is driven by a little belt that connects the 2 fans. these fans kick in to lower ac compressor pressure when pass a certain psi and also when engine temp passes 105C. there is a way to test them, put key in pos. 2.

Symptoms of a Bad or Failing Fan Clutch - YourMechanic.
If the fan doesn't come on, you need to look for a broken fuse or breaker. In older cars, you might have a fusible link - this is wire within an insulated block of rubber. If the wire stretches, the wire link could be broken, and you'll need to replace it. A sign of the wire link needing replacing is if your radiator fan fails to turn on.
The cooling fan in front of the engine does not spin anymore….
A quick spin of the fan blades with the engine switched off will show if it is working. The blades should run easily on their fluid face. You should also look for any signs of a fluid leak round the coupling. Should there be any problems then the coupling must be replaced. However, due to the complexity of the fan and coupling assembly it is unlikely that you will be able to replace the.
Which direction should the radiator fan blow? - Quora.
Without a shroud on the engine side, electric fans have trouble doing anything more than stirring up under hood air. Mounted on the outside, it is recommended to not use a shroud. As a shroud on the outside will do little in assisting how well the fans push air, and will only block a good deal of airflow when the car is moving. Y yragat Registered. That leads me to believe that the condensor fan and/or the radiator fan is not running to blow cool the refrigant. So I opened the hood and turned the AC manually to the maximum. Bingo, after a while BOTH radiator fan and condensor fan stopped running (high speed or low), and then for 30 sec of so, they will try to spin up for a split sec and. A pusher fan, in the context of a car's cooling system, is a fan mounted to the front of the radiator. Most often, a pusher fan is used in cars with significant aftermarket modifications and is.
