The last time I had to replace my PS pump was on my 99 burb and 95 sierra were 10 & 5 years ago. Both were different. Although I can't remember all the steps on the 99 I thought it would be the same but I don't remember it being so difficult. There are 3 bolts on the front underneath the pulley that I can loosen but not remove. There is 1 nut on the back that I can remove. It appears that the pump Is on the back side of the A/C bracket and the pulley is on the front. On the other 2 I used my pulley puller but it was after the pump was out. It appears that there is no way to get the pump out without first taking off the pulley. I tried pulling the pulley with my puller with no luck. After taking some pictures the pulley is held on by a large allen bolt. So I took of the dual bracket that holds on the PS pump and AC compressor. How to I remove the pulley with the allen wrench. I don't want to damage the pulley.
