Looking for a part

[Francine Henderson]

Hi. I bought my son a 1993 Pontiac Grand Prix GTP and I’m looking for a part to fix his car. It’s the timing belt tensioner (part number 24503860).

Sorry wrong forum, however for that DOHC 3.4 engine those tensioners are pretty much gone. Someone posted in a Pontiac Fiero forum in 2021 about 6-7 left among various dealerships out west but I doubt theres any left now. It was also said these actuators can be "rebuilt"

One website that came up in a search claiming to have them is http://oemcats.com/oem-parts/24503860.html#details. IDK if legit site or not.

Would love to see pics of it!

Moved to Powertrain.

I'll file this under "things i'm concerned about going into the future"

When I did my belt back in 2017 they were getting scarce then.

I've just reused 'em.

Wind the spring back after installing fresh/clean oil.
