1989 Isuzu Trooper Belt replacement help needed

I have a 2.6 4-Cyl 1989 Isuzu Trooper.

I am trying to replace the belts. I believe that removal of the fan is neccessary. There are four bolts that connect the water pump to the fan. Of course, they are on a pulley. Any suggestions for how to remove these bolts from the pulley? When I try to turn them, the pulley turns too.

I recently changed belts on my '96 3.1 td,i don't know if the set up is the same on yours,but i managed to slip the belts between the radiator and fan,then it was a case of slackening the tensioner on the pump housing,lining belts up on correct pulleys and re-tensioning

Make sure to replece the tensioner pully when you do the belt, there is a write up on this in a chilton manual that I have but I dont have it with me. I can look it up when I get home, dont move the camshaft around either when replacing the belt.

To get the bolts out of the fan, try using a air ratchet and wraping a shop towel around the blads and holding on or bracing it somewhere solid. I know that it is a pain trying not to bend up those fan blades. You could try some penetrating oil on the bolts too to soften em up. There is a industrial chemical they use in appliance repair that works great for that, I just cant remember the name of it. Also I'm assuming you have the radiator out for easir access.
Good luck with your repair

you dont have to remove the fan
you can take off the belts around the fan

I have the same engine and year Trooper and have just changed all the drive belts. They are difficult, becuase the belts I bought are really tight to slip on, but you can do it. Make sure you work from the block forward with each belt. Don't forget on the A/C drive belt you have to loosen the nut on the front of the compressor (20mm wrench I believe) then go under the vehicle to loosen the adjustment screw on the idler pully...it's about 4" long, adjust tension and then re-tighten the A/C pully nut on the front. The other adjustments are loosen nuts and pry to tighten...shouldn't have any problem with the rest. Good luck!
