So I changed my exhaust manifold and now after u put my belt back on it squeals really loud and I tightened my belt and loosened it but still squeals and when it does squeal the battery Gage goes down and my lights dim and I get worse gas mileage then b4 does anyone have any answeres

 

I'm no expert, but it sounds like it has something to do with your alternator / alternator pulley. That's the first place i'd start... I've had belt issues for a month now, sometimes it's fine, sometimes it squeals like crazy. It's so annoying... Good luck!

 

What brand belt you have? If it's mopar get rid of it. Chrysler belt sucks. Well back to point. I had a loose belt after changing pump. Never had it bad where lights dimmed. Not sure about that but I guess my advice would be is to make sure you adjusted belt using both idler pulley and the tensioner bolt.

 

yeah ill have to check its probly not seated rightor something stupid i have to change my power steering pump so ill check when i take it back off i hope its not my alternator cause that looks like a pain in the ***** to change but thanks for the info

 

Good luck. You can pick up an alternator tester from an auto store it'll tell you if your alternator is bad

 

check all of your pulleys for play or seizing, then I would just replace the belt. The lights and alternator dim because the belt isn't running the alternator, and its probably about time to replace your battery. No alternator works without being run, but if your battery doesn't hold enough charge to keep your lights bright...

Basically clean off your pulleys and change your belt.

 

yeah i hope its just the belt and nothing else but i guess fix one thing another one breaks my battery is pretty new so i dont thing thats it but i will have to see thanks for the help

 

You tightened the belt then loosened it? Did you loosen the idler pulley bolt before adjusting? The belt needs to be pretty dang tight, about 1/4" deflection pushing on the belt with your fingers. If it still squeals or slips the belt needs to be replaced.

 

when i took the belt off the ideler pulley was loose so i tightened it but that pulley is farely new but idk if it i got it tight enuff

 

It's hard to know if you read and understood my post. (btw google is a good spell checker).

Your belt is either not tight enough and/or it is old and slippery. If you can rotate the belt beyond 90 degrees it's too loose.

Yeah I can understand it I will have to check it out in the morning and see I just don't understand why I'm getting worse gas mileage

 

Get the belt sorted out then I'll bet your gas mileage improves. Low volts/amps from loose alternator belt will make your engine run poorly.
Good luck!

 

thank you

 

What ever happened with your rig. Did you find the problem

 

I changed the belt and o2 sensors seems a little better but not what I would like
