How do you change a fan clutch on a 2000 Chevy Blazer 4.3L engine? 2wd.?

Just had engine replaced with water pump, timing cover, and I replaced new the radiator, starter and a few other parts new to save some money considering i had done this. They said the fan clutch is going bad causing the car to heat up a bit. I never did one before and need some advice...How do you change a fan clutch on a 2000 Chevy Blazer 4.3L engine? 2wd.?Hi,first of all you need to take off your fan shroud,it will come off in half.two bolts on each side of the shroud %26amp; 3 on top that hold the rad.Then you need some special tools,a big wrench to loosen the fan clutch %26amp; one to hold the water pump pulley.I don't know how inclined you are,but if you take it to a shop,the charge should be no more than one hour.Good luck
