Anyone that can diagnose this problem without looking at it is good! First I pulled out the ac and power steering pump and put in a manual rack. Then I got some ASP underdrive pulleys. I put those on, got a belt that fit (very tight fit) almost too tight. I had to disconnect the alternator just to fit it on. Could there be any problems with the thermostat? I did not turn the tensioner after i installed the pulleys. Do you have to reverse the direction of the tensioner? Could this have been my problem with the overheating tonight? My pulley setup on my car is the alternator pulley, a free pully on the bottom left under the alternaor. The belt does run on this pully. On the right, just runs on the water pump and the crank. I took it out tonight and had problems but don't know what it was caused from. I did forget to plug back in the top plug to the alternator and found that out after I broke down. I don't know if that had anything to do with it. It broke down and was very hot but don't know if it broke down because of it overheating or because the alternator plug not on. With the plug not on, I was running straight on my battery; and if the battery (optima new battery) was low before that, it might have also hurt it. It took the car almost 35 minutes to cool even with the hood open. With the car off, the radiator fluid was full, but when I started up the car it sucked down fast and had to add fluid. Also another problem now is the idle. For some reason after I broke down, the idle is idleing at 2,000 rpm's. The timing is advanced to 14 degrees so with the underdrive pulleys and yanking out everything, do I have to lower the timing on it? Some other things to consider: I did not plug anything after removing the ac and ps pump. IS there anything you have to plug? Also, I am running those pulleys with the stock 65 amp alternator but ASP said that should be fine for now? If anyone has any idea on why I am having that high idle and why I had that overheating problem, please give me any ideas. Thank you

car running off the battery prob cause everything to reset. that would do with setting up the tps, google search it "tps reset mustang" and also setting the iac (you should be able to disconnect it, and it will run rough but as long as it dont die, if it still idles high back the screw out till it runs kinda rough prop 600rpm 700)so yeah and overheating make sure the water pump pulley is turning the right direction i believe its clock wise "some one pls correct me on that" best thing to do is pull at the stat put it in boiling water you should see it open then in cold water it should close good luck

thank you. it was a lot of help. but I think it is counter clockwise. Because before I had it at clockwise, and it was turning the right way. But I do think you were right with the other things. any one else have anything on this?

with the problem of the water pump turning the wrong way, would this work. Run the belt over the top of the tensioner and not under it and run the belt on the left side of the water pump. The water pump is a smooth pulley so would it matter if it would run with the top side of the belt on it. This would turn the water pump counter clockwise. Would it have enough power to spin the pulley doing it this way?

The water pump should run counter-clockwise. You need to make sure you have enough wrap around the pulley in order for it to spin properly. You want to make sure you don't have any belt slip. I'm not sure of a way to route the belt without any type of pulley on the driver's side of the engine.

if your running the water pump with the crank by itself then your turning it the wrong way, 5.0 water pumps are reverse flow, they are for serpentine set ups.

the pump turns clockwise with the smooth side of the belt touching the smooth side of the pulley.

No. I think the other guy was right. Because before I did all of the yanking out, it was turning clockwise. After I yanked out the ac and power steering pump, it has to turn counter clockwise. If it had to be clockwise, I would not have broken down. Yea, there was no play in the belt. Like I said in the first post, it was so tight, I had to loosen the alternator just to get it on
