i just bought a 01 supercrew 4.6 and when i step on it till like 3-4 thousand and up the battery light comes on and when it shifts to 2nd gear it squeels. does anyone have any ideas?

 

Change your belt and tensioner. It's a good idea to change your idler pulley as well.

 

Don't worry about #5, you most likley don't have one there.





Belt, 1 and 2. Use a Gaterback.

 

When the belts off, make sure and check all the pulleys for a nice smooth spin with no noise. Most likely the tensioner pulley like jbrew said.

 

so whats making the light come on?

 

Belts slipping. Like Toyz posted, check your pulleys. It could be a bad alternator pulley bearing as well.

 

ok ill check it out tom. it also has a check engine light on throwing a egr restriction code. replaced the sensor everyone said causes it and light came on 20 min later

 

Yea, you'll have to pull the throttle body elbow and ream the ports out with a round wire brush. They usually sell those at O'riely's/Murray's, but the best place is harbor freight. They sell a pack of wire reaming brushes that includes 3 sizes and 3 types = stiff bristle, stainless and brass for about 8 bucks.

Here's a a how to -

Here's a thread with a pic of yours and what needs to cleaned exactly -

If you end up needing an Alternator, - stick with a Motorcraft if you can. Not sure why, but these Fords don't seem to like anything but. Napa might be okay ? Iduno, but be picky on an alternator or you could be running back and forth to the store swapping out ones that don't work or don't last.

 

well it has a junk duralast from autozone on it now and i havnt had time to check out the tensioner or the alt. it tested out on the truck fine but im not sure why it is doing it.

 

battery light comes on 'cause the belt slips under heavy throttle. Mine did this too and I let it go till I had to put an alternator on it, then replaced both.

 

Also, I've worked on a 98 ( 4.2L not a 4six) that pretty much smoked most of the pulley bearings, - the tensioner was locked up. Allot of people change the belt and neglect the tensioners. Both should always be replaced at the same time. I'm guilty of just changing the belt and getting away with it, but you don't always lol. If you purchase a new belt from Rock Auto by chance - or just go to that site for the informational. Look up your belt (gatorback brand) and then click on details or info about the product. Gates suggests doing them both at once, -not just Ford. I've seen why. Just something to keep in mind.

BTW , believe or not, the bearings are bad if their tight. If their tight their either real dirty or in most cases, the baring has been overheated. That stresses others, also can take away some performance.

Your factory or original idler and tensioner pulleys should have a just a tiny bit of wobble, enough to notice, -barley , but you can. Test for wobble with the belt removed.

The alternator pulleys are a different story, = no wobble period, just the idler and tensioner pulleys should have a little wiggle. Some guys just have a better baring pressed in. The originals aren't that great and good quality high speed baring aren't that expensive. Could be all or part of the problem.

As mentioned before, check them all and see whatcha got. You'll most likley see what you have to do once you start checking a few things, when you get time.


Good Luck.

 

thanks aslot for the info
