Gates Accessory Belt Drive Kit

I'll be pulling the trigger on this kit this spring along with a new water pump most likely. Can someone tell me what the difference is between these 2 kits besides the part number and like $16??

Part number wise they look the same... one shows more detail than the other. I use OEM belts and rebuilt the pulleys with new bearings. The tensioner is a bitch to replace and the issues with mine were the pulley not the tensioner, however I don't think the gates pulley will fit on the OEM tensioner.

I dont think my issues are with the tensioner either. i suspect one of the idler pulleys is making the racket. They have a ton of surface rust on the faces of the pulleys so i can just imagine what the backs looks like. i just saw the whole package kit and figured may as well get all of it. I'll jump in your thread and do some reading before i pull the trigger, thanks!

 

It is often suspected that it's the tensioner/idler pulley making the noise but too often it's just the belt. It's been speculated that the pulley's aern't in "perfect" alignment so the belt will squeal eventually.

I switched to the Continental elite belt which was formally the goodyear gatorback and it's designed for this misaligned pulley issue. Fixed my problem 100%. Stock belt really started acting up at around 50,000 miles.

 

I dont think its my belt, the belt has maybe 15-20K on it. i'm really thinking it is one of the pulleys, but i might have to go back and check again when it gets warm.

here is my previous thread about this noise that started in November, i narrowed it down to something that is belt driven.

OEM parts numbers listed for each that the OP referred to are not the same, suggesting they are for 2 different vehicles.
