Slipping drive belt?


adallak

Recommended Posts

My car has been killing batteries for years. Several tensioners, belts, alternators, batteries were replaced to no avail. Sure, I measured parasitic drain, voltage drop at cables, etc. I still suspect the belt is slipping. The steering has been harder than it was supposed to be as well. The effective length of the OEM belt is 1633 mm. I found a BANDO 6PK1630, ...1625, ...1620 belts, which claim effective length of 1630, 1625, 1620 mm. What difference in effective length would make the difference between nonslipping and slipping belt? Thank you.

Adallak, I hope all is fine.  My gut feeling is that if you had a slipping belt it would squeal.  

Check the resistance of the battery wires, if they have oxidized they will draw more, and hurt charging.

Thanks, Mike. Will check the cables again. No squealing whatsoever, but steering is harder than it was when I bought the car. That makes me think something is wrong with tension/belt.

Maybe, but my experience is that you would feel jumping if it slipped and it would be accompanied by a squeal.  Ill research what causes increased steering effort.  My guess is steering column bearings.  Lets do some thinking

By the way, do the belts appear to be glazed from slipping?, if it is slipping I think you would see evidence.

There are too many variables here between the 2 issues.

Stiff steering can be caused by 

tight balljoints, tie rods, strut bearings, weak pump, column bearings (rare)

I have never had any issues regarding belt length on these. I usually run a good quality gates or dayco belt. Or ACD when I can find them.

Look at your tensioner and see where it sits with tension on it normally, If it is good it should be about half way between each limiter. 

Have you checked your grounds? That can cause issues as well

No glazing at all. I have a half a dozen belts.All look good. Three tensioners, six batteries, the second alternator in 10 years, 40,000 miles ( I do not drive as much as I used to do).

The car is pretty clean, have not been neglected. The grounds look okay. Currently, a new ACDelco 6K642 is used.
