In order to replace my water pump housing, I have to get the crank pulley off. (I've got a 6 groove for the SC serpentine, and two V grooves for PS & AC) I removed the four small screws, but it doesn't want to budge. I'm assuming I have to take off the large center bolt and what appears to be a washer below it. Am I correct, and how do I get this off?

 

The large bolt doesn't need to come out to replace the water pump/housing.

 

All you need to do is take off the four bolts. I just removed my pulley, and it took a lot of force/tapping to work it off.

 

mark it first before you take if off; otherwise, you may put it back incorrectly.

 

the bolts are off center; ie, all 4 holes only line up a certain way. There is no need to mark them.

 

are you kidding??? that how many people screws up their timing as they cant put it back to its original spot. you can put it back in different ways but how would you know that your on the right mark.
