Why ruin your truck. The clutch for this fan is not expensive or hard to replace yourself. The clutch allows the fan to operate at different speeds when necessary. The top of the fan shroud comes off and the clutch comes off easily when wrenched in the opposite direction of rotation. unbolt the fan from the clutch and bolt the fan on the new clutch. wrench the new clutch/fan back on and reinstal the shroud.

I wouldnt use a fixed blade fan. Altho it is a big block the fixed blade fans rob alot of power. Not to mention the temp. difference changing the ect and throwing off the af ratio, but to each his own. hope this helps !

Depends on the year but some of these engines require the clutch. With a non-clutch fan, the blade direction is reversible.One way blows out and one blows in, make sure the slant of the bladeis the same

Are you talking about switching to electric fans? or a standard fan that will run all the time?

I am going to assume that you checked all your linkage to insure all is well. So now I am going to take a stab in the dark and GUESS that when you relaced the disk and pressure plate you must have inadvertently installed the disk backwards. This would have positioned the springs against the flywheel still allowing enough disk, flywheel, and pressure plate contact to function for a short period of time.

I have a 1995 Chevy 2500 6.5 turbo diesel and the blow. So I was wondering if theirs any gas engines that will bolt in its place? thanks D Hawkins


Any smallblock chevy to a bigblock chevy will bolt up. examples I would go with : 350 or a 454 . The 6.5 uses the same transmission bolt pattern as these engines. If it's an automatic the flywhell might still work on the 350 or 454.

How many lbs. of freon for 2000 chevy silverado 2500 5.3ltr.


if its a new body style (with the round front - i am assuming because it has a 5.3) then it takes 2.0lbs (.91kg). Make sure you check your fan clutch to see if it spins freely or has some drag to it. the fan clutches usually fail causing the compressors to come apart, the failed ones spin freely.
