If i remove the impeller, can it still be used as a idler pully. I dont want to have to reroute the belt drive. It is for my puller, Will the berrings be ok with out water to cool them.
I don't think a water pump bearing will live long without coolant, but I've also never tried it. It's a small bearing and I think the bearing speed will be excessive with no coolant and is gonna cook itself.
i plan on doing this as well. I still have the alt, but removed the fan hub so i can take the front cover off easier. i had considered drilling it for a grease fitting. that being said, making a mount to bolt on an idler pulley like is on the tensioner or a 3rd gen would be easy as well.
