    The easiest way is to loosen them before you remove the serpentine belt. If you've already removed the belt you can try wedging something between the pulley and the old water pump.
    Good Luck!

Replacing water pump


To replace water pump on Chevrolet s-10. You need take of the top half of the fan shroud, pop off the hoses to the water pump and the take out the bolts to the water pump.To get the fan off, you need a special tool called a half h tool, The half H tool holds the bolts in place so you have leverage to then twist the fan off.Before removing parts to replace water pump first drain the antifreeze.Place the drain pan under the radiator, open the drain on the bottom of the radiator and allow the antifreeze to drain into the pan.Remove the upper fan shroud using a 10-mm socket. Remove the four 13-mm nuts securing the radiator fan to the water pump pulley, using a wrench.Pull the water pump pulley off the water pump. Remove all hoses from the water pump, including the lower radiator hose and upper heater hoses. Remove the four bolts securing the water pump to the block, using a 15-mm socket and ratchet with the 3-inch extension. lift the water pump off the block. Clean all the remaining gasket material off the block passages using the gasket scraper. Lay the new water pump face down with the outlet ports up.And complete the procedure of fitting the new water pump in reverse of how you removed the old one.---------------- Thank you.

I need to replace the fan clutch on a 1993 Chevy S-10, 2.8 V-6. I have removed the fan cowling. Must I remove the fan as well or just unbolt the clutch?


Your almost done! Remove the fan and clutch as one then unbolt the fan from the clutch. Install fan onto new clutch and reinstall back onto water pump. Put your fan cowling back together and you are done! Good luck!
