I have have high pitch wind noise from fan clutch after replacement is it normal on new fan clutch


Fan clutches are stiff and loud till vehicle runs a bit, as fan clutch mechanism warms up drag on clutch mechanism releases pressure and will free wheel.
Do not mistaken this with, when engine hot, clutch engages to help cooling system which is normal.

2003 Nissan Xterra - Fan noise when a/c on


No that doesn't sound like the problem, the fan clutch locks up to cool the engine off due to the increased load of the AC system on the cooling system, so it locks up and gets much louder. If it didn't lock up the engine would overheat.

Air conditioner fan is making a loud noise


1. Could be a caught foreign object between A/C (air conditioning) fan and cooling radiator, producing this loud noise.
2. Could be a damaged fan blade, mowing the cooling radiator.
3. Could be a loud noise comming from the fan's electrical motor.
4. Could be a broken off fin (small wing) of the cooling radiator, striking the A/C fan, producing this loud noise.

I have a 2006 gmc envoy xl that sounds real loud like a jet when you start it up and when excelerating it gets louder and louder. Could it be the fan clutch or the relay any answers anyone


Fan clutch failure is common on these........and very costly to replace. With the engine cold, engine off, reach in and turn the fan, it should turn with minimal resistance, if it has heavy drag, or wont turn at all, it needs replaced.

Motor fan is extremely loud!!


It is likely your fan clutch has gone bad and needs to be replaced.
Fan clutches are engineered to improve the vehicle’s cooling system efficiency. The clutch engages the fan at low speeds when additional cooling is needed. At high speeds the clutch disengages the fan, removing the load against the engine and allowing the engine to run more efficiently.
There are two types of fan clutches, non-thermal and thermal. Non-thermal fan clutches engage the fan based on the shaft speed of the water pump. Thermal fan clutches engage the fan based on a bi-metal thermostatic coil, which senses the under hood temperature.

It will look like this...

Engine makes loud roar


It sounds like a fan clutch has failed.

A fan clutch is a thermostatic device that exists as an integral component of certain automotive cooling systems. When the engine is cool or even at normal operating temperature, the fan clutch partially disengages the engine's mechanically-driven radiator cooling fan, generally located at the front of the water pump and driven by a belt and pulley connected to the engine's crankshaft. This saves power, since the engine does not have to fully drive the fan
