Hi. My 1994 bronco 5.8L xlt is shreding the serpentine belt. All pulleys are in line, I've replaced power steering pump, The problem seems to be the crankshaft pulley, as the belt seems to ride on the front outside edge insted of the inside groves. I've replaced the old pulley with a new factory one. I've thought of putting a backing plate behind the pulley mabey 1/16 " to bring pulley out so belt will track inside the groves. I can't find one from ford, so I was thinking a machine shop could make me one, but they want $180 to $250 which seems like a lot. Any suggestions would be greatly appreciated and thank you in advance. I realy love my bronco, and hope there is a solution. The motor is solid and in very good shape, it has 197000 miles. I change oil every 3000 mi. and just gave it a full tune up and it realy runs great. My e-mail address is [email protected]

I would avoid that entire dilemma by just taking out the whole ps pump and replacing the pulley then, seems like a lot of work but it's worth it cuz the radiator removal is way more involved and more likely to cause problems with antifreeze leaks, also you probably only have to tilt the PS pump to get the pulley off so I would not disconnect the power steering hoses until I absolutely had to

place a drain pan under pump. disconnect negative battery cable. remove inlet and outlet hoses a.d let drain. remove the serpentine belt from the pulleys by loosening the automatic belt tensioner. remove the three pump mounting bolts and the pump. using a suitable pry bar remove the retaining clips from the reservoir separate the reservoir from the pump. install the reservoir to the pump with new o ring seal. remove pump pulley and put on new one.

the power steering pump locking up is the reason ur serpentine belt broke. on front of power steering pump is a pulley which must spin freely. when this pulley locks up, things break...and yes u definitely need a new power steering pump.

Remove the alternator/power steering pump and water pump drive belt to gain access to the air conditioning drive belt.
To remove and install the air conditioning compressor drive belt, first loosen the tensioner pulley lock nut, then turn the adjusting screw to raise or lower the tensioner pulley assembly Accessory Drive - 3.3L Engine or Accessory Drive - 3.5L Engine To adjust the air conditioning drive belt, loosen the tensioner pulley nut and adjust belt tension by tightening adjusting screw. Torque pulley nut to 54 N•m (40 ft. lbs.) after adjustment.
The Poly-V generator/power steering belt has an adjustable tensioner pulley located on the timing belt cover Accessory Drive - 3.5L Engine to maintain proper belt tension. To remove or install this belt, Release tension by loosening the tensioner pulley nut and adjustment bolt Accessory Drive - 3.5L Engine Reverse procedure to install and tighten belt to specified tension.

Make sure the serpentine belt is still on the engine. Sounds like a pulley seized and the belt snapped. The belt runs everything including your alternator which is likely why it isn't running right...eventually it will stall and not start, or, overheat.

3.3L?
Looking at the engine from front (right side of the Van): Stating at the Top, Going Left to Right and Clockwise:
Over the Alternator
To under the Idle Pulley,
To Over the AC Compressor.
To the Left Side of the Water Pump.
To the Right side and Under the Crankshaft Pulley
To the Right side and Over and Down the Tensioner
To Under the Power Steering Pump
And Back up-to the Left side of the Alternator.
Advise when puting it on:
Put the Belt around everything else accept for the Alternator. After it is around all the rest of the Pulleys - Pull the belt up - tight from the Power steering Pump and the Idle Pulley to form a loop, holding the Belt close to the Altenator Pulley.
Using the 15mm wrench or belt tensioner bar - rotate the Tensioner Pulley towards the front of the Van and then place the belt over the Alternator.
Let me know if this helped or if you have additional information or questions. Feel free to contact me at FixYa.com!

Either the tensioner is defective and needs replacing, or the pulleys are out of alignment. I would suspect the tensioner pulley is bad. I am assuming you are installing the correct belt.

HI, this is the result of a worn power steering belt. in this case, the pulley may be worn or, the entire serpentine belt may be worn altogether. have the power steering pump inspected for pulley and gear damage. inspect the serpentine belt for worn sections as well.

Most common issue will be a worn drive belt(serpentine)

That is a valid question, but you should ask the shop that worked on it. Also do you know that the power steering pump will cure the problem? This remains to be seen....You can check one thing though...Look at the belt/pulley arrangement from the side. any pulley that is not exactly in line with all others, and any wobbling pulley is suspect. Serpentine belts are far less forgiving of these items than were "v" belts.
Good luck

3 bolts should be holes in the pully too go thru with an extension if their are no holes in the pully then you nee a power steering pump pully remover it can be rented for 5.00 at auto zone
