Brand new massive 21" GM Duramax HD cooling fan with special fan clutch which will adapt the Duramax high volume fan to your 2001-2005 LB7 and LLY diesel engines. From SSDiesel Supply^TM, the 6.6TD specialists.

This Duramax fan and brand new special clutch is less money then just a new fan clutch alone! The clutch is Severe Duty and made and modified in the USA. Engagement is approximately 15 DF sooner then your stock clutch for better cooling.

This fan really sucks! Just stand in front of the grill, it will almost pull you in! It will not hurt mileage as the clutch only engages it when necessary. A must for towing, but highly recommended for all 6.6's to prevent overheating, which we all know are prone to. This fan alone makes a big difference in temperature. and will keep your diesel super cool and help prevent the common problem of head cracking. Now is the time to get it ready for the heat!

Buy from the experts on GM 6.6 TD's.

The air temperature coming through the radiator is sensed by the bi-metal thermal spring on the front of the thermal fan clutch. It expands and contracts with the change in air temperature operating a valve inside of the clutch. When cold, the silicone drive fluid is pumped from the working area to the reservoir. When hot, the valve opens allowing fluid from the reservoir to be transferred to the working area thereby increasing the fan speed. The clutch disengages as the air temperature decreases, closing the valve and allowing the silicone fluid to be pumped back into the reservoir.

A thermal fan clutch is engaged on a cold startup because the fluid drains into the working area when the engine is shut off. The fan clutch will slow down shortly after startup as a result of a pumping action produced by a difference in speed between the shaft and the body of the clutch.

Our Special Clutches are specifically designed to engage at lower temperatures than the original equipment parts that they replace.
