Serpentine belts... oil leaks...bad sending unit? Ahh!
I've gone through three serpentine belts in the past month... and my current belt is being torn to shreds. This is AFTER I had a professional mechanic install the serpentine belt and my boyfriend aligned all my pulleys to ensure my Jeep wouldn't eat another belt. I can't figure out what's going on. My only guess would be that my alternator is an aftermarket alternator and has a 5 rib pulley instead of 6 rib like all my other pulleys. Could this be a possibility? I have a pretty expensive, pretty beefy alternator and don't want to get rid of it if that's the cause. Could I just replace the pulley? It's a Powermaster alternator. Not sure on the exact model.
As for the oil leak... I thought it was the gasket on my oil pan. Actually, I was pretty sure the old gasket was the cause of the leak. After replacing the gasket, I'm leaking oil about the same as I did before, maybe even worse. We ran a couple beads of silicone around the gasket and tightened the bolts to the correct torque.
The funny thing is, my Jeep only seems to leak in the parking lot at work, not at my house. Last night when I got home, I put an old white rug under my Jeep to see if it leaked at all. I had one drop, smaller than a dime. At work, I had a significant size puddle. The strange thing is, my oil level has stayed about the same. It may have dwindled a teeny, tiny bit, but not enough to say so or justify the puddle. Any ideas???
Also! Before the gasket/oil/filter were changed, for the first time ever, my Jeep was burning oil. BAD. Now, it barely even smells of oil when driving/idling. I did do a really deep clean of my engine bay-- even broke out the degreaser. When changing the oil filter, it appeared as though it hasn't ever been changed. So I think the new one has definitely helped.
I do not believe that I'm leaking any coolant, and my Jeep hasn't overheated. Brand new thermostat in it.
Sorry for rambling... but I really would like to figure out what's up with the leakage and serpentine belts.
Vehicle details: '89 YJ that originally had a 2.5 4 banger in it. Engine was swapped out for a 4.2 I6; complete engine rebuild about 22K ago. Runs like a champ, aside from the recent issues that have developed.
I'd appreciate any helps or tips that I can get. Thank you!
