Installing the Serp. Belt

[Lynn D. Brown]

Hey Guys - to install the Serp. belt :

Do U wrench on the 15 mm bolt that holds the Tensioner on there to compress the tensioner so U can slip the Serp. belt on ? Clockwise ? so U R trying to tighten the bolt - hope I don't strip out the threads ? Or is it Counterclock ? - this might loosen the bolt

Havent changed it in a while, but that bolt just holds the tensioner to the engine. So dont touch that one. Im pretty sure at the end of the tensioner there should be a square whole to fit a 3/8 rachet in. Once you got the rachet in you can only turn it one way to loosen the belt. Good Luck.

OK, I just found the bolt - it's the one on the idler just below where U bolt on the tensioner. It also looks like U have to remove the fan. Of course, just after I put it on with blue locktite.

So, does everyone agree, U have to have the fan off to install the belt ?

No you do not have to remove the fan. Yes the bolt on the idler is the one to rotate the tensioner to install the belt
Just look at the belt diagram on the decal next to the emissions decal.

Yes, you don't have to remove the fan. Just slip one of the belt (in a loop) around the side of it. I run the belt on all the pulleys except the alternator. Then I crank the tensioner up and slip the last of the belt over the alternator pulley.

Patrick & Bill,

U were right ! Thanx - U guys may have saved me some time, as I might have removed the fan. This would have been tough, because I don't have the clutch fan where the fan will detach from the clutch assembly. I have a flex fan and the whole thing would have had to come off, including the pulley.

Yes, U have to line up the belt on the Pass side, and totally loose on the right side. Then U go around the crank pulley and then back around the center fan idler. This is where U have to gradually bring the belt back over the fan blades one by one, as U turn the fan, to get back to the Drivers side accessories. Once U get it on, U see the belt ribs facing out on the center fan idler and the idler to the left of it.

I have done lotsa Serp. belts, and they R usually obvious. But of course on these monsters, it isn't obvious and is more difficult. Is there anything easy on these beasts ? About the only things that R easier than the GN's is the water pump and the AC compressor.

Ramble, ramble, ramble.

It's much easier to work on SyTy's when you've had a few years of NA 4.3L non-AC S-10 practice first. =) Same basic stuff, but not nearly as many parts to get in the way.
