Re: Upper radiator hose
From what Ive read get an upper hose for a Camaro RS of the same year. Some RS camaros came with a v6 and some with a v8. You want the upper hose for the V8 which was a regular tbi engine.

I used a 24" Gates flex coolant hose I ordered from Jegs. The tbi coolant hose didn't work for my setup for some reason.
