Replacing Clutch Radiator Fan with an Electric Fan on a 1999 GMC Yukon


Im about to replace my clutch fan with a electric fan on my 99 yukon. But I wanted to know which fan would be the best 1 to get a pusher or puller? And like what specs should I look for when purchasing?


Expert Reply:

Pushers are more efficient and more common. A puller is typically only installed when you don't have enough room between your engine and your radiator.

It looks like your 1999 GMC Yukon has a 5.7 L V8 engine which means you would want to shoot for a CFM (Cubic Feet per Minute) range of 2,200 - 3,000. The most popular fan that we have in this range is the Derale 17" Radiator Fan # D18217 which has an output of 2,400 CFM.

When it comes to fitting your vehicle it really just depends on what kind of room you have. I have attached a link to a helpful article as well as a picture giving the dimensions of this fan.

If you want to operate the fan manually then you will want to use the Switch # D16740 to do so. Otherwise the Single-Stage Thermostat Fan Control # D16735 for a thermostat option which turns on automatically.
