    Water Pump Belt Tensioner

    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!

    Re: Water Pump Belt Tensioner

    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.
