Ok this is no big revelation, but I thought of it and it worked nicely for me, so I thought I'd share, just in case...

We all know the belt should be lubricated, and that it can be over lubricated, and that oil and other crap tends to get on our serpentine belts.

Before I get to this, let me stress to BE CAREFUL if you use this method, as there are some obvious dangers present, both to the vehicle and yourself. I did this on my 1990 Fleetwood, and the belt accessibility favors this method. Keep that in mind in case it's not so on other vehicles.

Anyway, I had oil all over mine thanks to a leak which I fixed, and particles of junk in it and everything. Trying to clean out the tracks of the belt and the pulleys and everything would have proven a most annoying task.

First, just start the car and let it idle. Get a can of silicone spray and plaster the belt with it. Then take a rag and hold it against the top of the belt. Spray the underside of the belt as well (On mine it wraps over the water pump with that side up). Between the air pump and power steering pump, again on the 4.x engines, there is room to press the rag on that underside of the belt. This is where care must be taken. Keep a good grip on the rag, as you sure don't want a pulley to catch it and jam it up like so...and even more importantly, your hand(s). Anyway, I got lots of gunk off my belt and it smoothed out well after doing this several times.

Haha, a pulley wouldn't have any problem eating a rag. My belt got ahold of my power wire and fuse holder (for my amp) after a zip tie failed, ate it, spit it out and didn't miss a beat. Not like you want it to eat the rag, but still.

Yeah, you're not gonna see this procedure in any safety videos, I assure you of that..... Yikes. If it grabs the rag, it's gonna happen REAL FAST....

Just a thought.

I would be very careful of spraying silicone around the engine compartment. If the silicone gets sucked into the intake, your Oxygen Sensors will get contaminated.

Haha, yeah I thought it might eat the rag ok, but I was putting a disclaimer there for that as well, because if it gets the rag, your hand may follow on said rag :hide:. Just know this isn't an "approved" procedure, like Patrick said, and be careful. Don't let any of the rag hang off of your hand. On the top side of the belt (on my car), as long as you're careful, there's not a lot of danger of it catching... It's more the underside. I went between the air pump and the power steering pump...only spot I could get to it...and that, I definitely used MUCH caution.

:thumbsup: Yup, silicone + O2 sensors = $$$$$$$

frankly , i would just install new belt

I am well acquainted with an ex-submarine engineman, missing the first two fingers on his right hand, who tried exactly what you suggest. A $36 belt is cheap compared to the mess you'll have to clean up after a pulley eats you.

LOL, yep! That's a mishap report ready to happen!

At Advance we sell a speical "belt conditioner" spray made just for this.... I haven't seen the need to it tho.
