I was overheating, I changed the thermostat/housing, radiator and hoses, temperature sensor for electric fan, and water pump and flushed the cooling system with a T kit and Prestone super flush.
When I changed the thermostat I got antifreeze all over my belt and pulleys, a lot, it squeaked but it went away. Anyhow, I was trying to solve an overheating problem which I did in the record breaking 103 degree Austin, TX heat. Awesome. That's saying something especially considering that I drove around on a bad belt for about 40 minutes which I didn't notice but the mechanical fan was weak and should have been the first sign.
The mechanical fan was barely turning, alternator, everything connected to the belt was moving slowly. I almost had a dead battery. I parked it and I thought I needed it tighter so I adjusted the tension er and tightened the idler pulley and I almost choked the engine. I stopped, then I let the tension lose and it just proceeds to run rough, jumping and stuff.
I have a idler pulley on my 1996 Jeep Cherokee I6. FIrst, you adjust the idler pulley screw, then adjust the 7 inch tensioner screw(behind pulley on bracket) that the idler pulley slides on to adjust tension. that I used to adjust tension. I have notice the idler pulley looks a little uneven but I can't be sure.
My pulleys look a bit shiny but they already looked fairly shiny. I am going to wash the pulleys and belt with soap and try it one more time.
Then I'm going to wash the pulleys again and buy a new belt and idler pulley.
Is there any kind of lubricant to use on the pulleys. What can I do, the engine was running fine until I did the thermostat and water pump. Also, all the pulleys trn really easy except the water pump has a little resistance but can still be turned fairly easily.
