Hansan, I need to remove the idler pulley to access one bolt on the water pump. I did remove the power steering pump, but I still need to remove the idler to get the last bolt. It may be a star or torq drive, but I haven't been able to get either to fit right. It does seem really tight, and it may have left hand threads. Any suggestions? Thanks

Re: 97 Grand Prix GTP
There should be a torx socket that fits it pretty well. as far as being lefthand thread, I think that those are normal threads. usually its the idler pulleys on fords that have a lefthand thread design.

To get that last bolt out you need to move the power steering pump out of the way. Just remove the two bolts holding the PS pump and push it aside. You don't have to remove the pump hoses you just need to move it an inch towards the firewall.
You do not need to remove power steering pump, you can rent a power steering pulley puller tool from most auto parts, just remove the pulley, its much easier and faster, they you can get to that end bolt on the water pump.

no you have to go thru the holes in the front of the power steering pulley. Usually a ratchet with a deep 13mm socket will do to remove the 2 bolts located at 12 and 6 o'clock then you will be able to move it out of the way
Hope the following will help. 1) Drain the radiator. 2) Loosen the 4 bolts on the water pump pulley. You will remove the pulley and install it on the new pump. Just loosen the bolts 1/4" turn with the belt still on, this will prevent the pulley from turning. 3) Remove serpentine belt. 4) Remove 4 bolts and the pulley and set aside. 5) Remove two power steering pump bolts (15mm). You must do this because one of the bolts for the water pump is behind the PS pulley, and you can�t remove it without moving the PS pump out of the way. The bolts on the PS pump are in the 12 o�clock and 6 o�clock position. There is a large access hole in the PS pump pulley. Just line it up, slip in a long socket and remove them. Let the PS pump rest on the oil filter housing. 6) Remove water pump. There are 4 large bolts (15mm) and 4 small bolts (3/8") on the water pump. After the bolts are all out, I placed a length of pipe on the water pump and gave it a couple taps with a hammer and it popped right off. 7) Remove old gasket. The tool of choice IMO is a razor blade like you�d use to remove a winshield inspection sticker. Be careful not to score the mating surface. Remove old gasket and dry off surface. 8) Seat the new gasket and water pump in place, install all the bolts. 9) Reinstall the PS pump and torque bolts. 10) Install pulley on water pump and torque. 11) Install serpentine belt. 12) Re-torque bolts on water pump pulley if needed.
