Replace the serpentine belt

I just finished replacing mine.

It is much easier if you do these steps:

1. Remove the serpentine belt.
2. Remove the nuts holding the main fuse box over the battery.
3. Remove the reinforcing bar over the battery.
4. Remove the battery.
5. Remove the windsheild washer tank.
6. Now you have access to remove the pump pulley. Without removing the stuff, it may be possible, but it will be extremely difficult.
7. Remove the pump pulley.
8. Loosen the high pressure hose fitting.
9. Remove the return line clamp.
10. Remove the power steering pump mounting bolts.
11. Remove the high pressure hose fitting.
12. Remove the power steering pump while sliding off the low pressure hose.
13. Remove the clips holding the reservoir on the pump.
14. Remove the reservoir.
15. Install new o-ring on the reservoir.
16. Install reservoir on new pump.
17. Install clips to hold reservoir on pump.
18. Install new o-ring on high pressure fitting.
19. Place new pump in position while sliding on low pressure hose.
20. Loosely attache high pressure fitting.
21. Tighten pump to mounts.
22. Tighten high pressure fitting.
23. Install clamp on low pressure hose.
24. Install power steering pulley.
25. Install washer reservoir.
26. Install battery.
27. Install reinforcing cross member.
28. Install fuse panel.
29. Install serpentine belt.
30. Bleed the power steering system.

Hi,
That belt you have seen is a balancer belt, used mainly to eliminate the engines vibration. Actually invented by Mitsubishi, as we all know Hyundai and Mitsubishi have common designs. Thus, all Mitsubishi patented design can have Hyundai's stamp on it!
Hope that helps you out!
Thanks for using FixYa!

Sounds as though one or more pulleys maybe bad. Take off the belt,firmly shake each pulley to be sure all are secure. The power steering pump pulley shaft has most likely gone bad. May need to replace.

You mean your belt tentioner, serpentine belt, it is not adjustable if your belt is coming off you have a bad tentioner, bad pulley or your power stering pump is leaken and your belt is soaked, if oilly firts found your leak (most common is a hose from reservoir to pump) then replace belt with a cheap belt (had lost of trouble with Life time or hi dollar belts), in the mean time also inspect your tentioner if ani play side ways replace it, also remove idle pulley and spun it close to your ear, if any noise replace it, you may get away with a single item changed, but for trouble free time, replace all items: belt tentioner ($38) idle pulley($25) serpentine belt ($25)

Hope this helps ya.. Cobra... :-)

I have never heard of a spare pulley on an engine. If everything is working, (alternator, water pump, power steering, AC compressor ) then I guess I would not worry about it. The only other thing could be that some one placed a belt on the truck just to get it by until they could get a correct belt to fit. They are routed on top and below pulleys and it is possible to skip a pulley temporarily if you get a smaller one to get you by until the correct one can be located. Good luck

Could be anything that is attached to the serpentine belt. ie: starter, water pump, A/C compressor, tensioners, steering pump.

My guess is a bad idler pulley bearing (cheapest to replace).

How many miles, what year is vehicle?
