Ever did one with the eAssist? Im replacing the water pump pulley thats on the accessory belt side (crank, a/c & water pump). Since its a stretch belt, gonna try n do the zip tie thing. my next question is do I have to remove the main drive belt to spin the crank pulley or do I have to remove that belt too? The main belt on these 5.3 eAssist is a b!tch to remove n put back on since theres not much room. Would really appreciate your help and knowledge about these eAssist models. Not much info out there
