I wish you could buy these aftermarket, but I couldn't find them anywhere so here we are. The price is not great but they work and fit like they're supposed to.

Worked well. I replaced these while replacing the belt tensioner on my 2000 Buick Lesabre. I also changed from the plastic coolant elbows to the metal ones.
