fan nut wont break loose off water pump

[belz]

Trying to change the water pump and cannot break the fan nut loose. Any ideas? Tue fan nut wrench set I got from the autoparts store isn't working. Tried the air hammer and it didn't work.

the air chisel didn't do it ?

Apparently u need a long barrel air hammer and I have a short barrel. I know, haha, short barrel. LOL

I used a 36" pipe wrench on the nut, and a chisel from a rotary hammer with a cheater on it. Did the truck pretty fast.

you are turning the correct direction. it might be lefthand thread

I has to be turned clockwise as your facing the front of the motor, and its a 36mm wrench. Most autoparts stores should have a kit you can rent. Also don't take the tension off the belt till you get it off.

I have found that a breaker bar in the tensioner, tightening the belt further will stop the pulley from spinning, you may need to heat the nut with a (propane) torch and then spray it with some penetrant. You need to get close to the edge of the flat of the nut in the direction you want to go with the air hammer and ease in on the trigger gently until you get a decent dent in the nut going. It helps to have a 2ft round tip chisel to put your weight into. Then change your angle a little, when it breaks loose, follow it around.

Never had to heat on up before, but if you have an air hammer just go rent one of these or buy one and make your life a lot easier.
