    Use a cheater bar and have a strong friend help you out. Mine was on so tight my buddy who is huge using about a 3ft cheater bar almost couldn't get it off.

        Break free by turning the wrench toward the drivers side since its reverse threaded, after you knocked the nut free. If you cant break it free, have someone apply pressure to the belt with some sort of object, if you still cannot get it free, cut the belt and use vice grips to hold the pulley and pull the wrench back.
        I worked on a member's car here and there was loctite on the nut/waterpump hub, i thought my bones were going to turn to powder trying to break it free.

          I bought a new water pump, couldnt break it free, so I bought a new clutch and smashed the old clutch to bits with a BFH to get the pulley.

              On the idler, do not use the bolt to "walk" to adjust the tension. Use a breaker bar to pry the alternator back enough until appropriate belt deflection is achieved, then push the teeth in on the idler bolt. You can just counterhold the 19mm idler bolt in while you tighten the 13mm nut on the back.

                  +1. You can hold the water pump pulley in place by wedging a long screwdriver in behind the fan clutch. Use the 4 bolt heads on the pulley and get your screwdriver in between them. This worked like a charm for me.

                    the best way to get it off is with a good quality tight open ended spanner. get it on, and bang on the end with a hammer to loosen the threads. then with a BFH just knock it. even without holding it back, comes right off.

                    i used a 30mm wrench that was grinded to just under 32 mm. had to bang it on. first attempt with those flimsy bike wrenches completely failed.
