Can anyone tell me if the water pump tensioner assembly is still available for a 93 Northstar? Don't need one now but if they are getting scarce I would like to have one just in case. Blame it on my OCD!
You don't need the whole tensioner - the pulley is what fails and it is available and replaceable separately. ~$24.
Look at RockAuto, your car, engines, belt drive, the 3-rib pulleys. Gates is just fine.
Talk to Chris in parts at Rippy Cadillac over there >>> N - S business hours EDT.
Pictures of the water pump drive parts, removed pulley and diagrams in my albums. Community tab, Albums, the red Seville.
EDIT: Looked in RockAuto - 3-rib belts available, but do not see either a complete tensioner or a pulley for a 1993 Northstar. Check out listings for a 1993 Northstar Seville or talk to Chris. Maybe www.gmpartsgiant.com. Also, NAPA has the (later) pulleys - try there.
Last-ditch effort: Remove the existing pulley, carefully remove the grease seal on one side, wash it all in mineral spirits, blow dry and repack with wheel bearing grease. Fit the seal carefully, making sure the small outer retainer lip is in the pulley groove all the way around. My pictures.
FYI, my '93 crapped out last Tuesday. I got on the web and found some good information, some used ones on eBay, but no new ones. I tried Rock Auto and several other links, but in Canada I found a lead to Northstar Performance dot com
group that has new ones in stock and not much more expensive than the most expensive used ones on eBay. You tell me, since my OEM went 57,000 miles, how many miles does that used one have and how long before I need another? And
since it seems to be assembled without fasteners, how does one take it apart to lube, replace pulley or do anything?
