Question about 1998 GMC Jimmy
Posted by Anonymous on
I believe the treads are conventional (right handed) meaning...you would screw the nut on clockwise...or to the right...to put it ON. So...you would put your wrench on and turn counterclockwise to remove. The tricky part is two-fold. 1. The proper wrench...2.Snaping the fitting with enough impact, that it will break it loose. The wrench (as you have probably figured out, needs to be a large one. ( I want to say these are an 1 1/8- to 1 1/4 SAE. or 28-38 mm) Not everyone has wrenches this large and attempt to remove with Channel locks, adjustable wrenches or the like. This can be an exercise in frustration. If the proper tool is not your problem, it might be the lack of impact...and holding the water pump pulley in place...as it freewheels on the shaft (something else you are probably painfully aware of) you do not want to damage your pulley...so carefully snap a small pair of vise grips on to pully...or hold a large screw driver in such a way as to impede its movement. With the proper wrench in place and pointed upward....wrap some duct tape or something protective around the top of the wrench, and give it a good firm whack with (preferably a brass hammer) to the left. keep in mind...Impact does not mean beat the hell out of it....it means once you have the pully stationary and the wrench squarely on the nut....its the instantaneous force that happens when struck by the hammer. It will only take one good lick when properly executed. If you would like to check to be sure on the thread type...you might try.....>>>
