Air Shut-off Valve (aka cowl air-door) Spring - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was just recently introduced to this valve, which sits in the RH corner of the cowl. Word is the spring is hard to come by, but a similar spring may work.

I believe I've found the spring or real close.

Hint: Can locate the springs on FeeBay.

Reference:
Air-door valve (Possibly 3895485).
Potential spring replacement (3840842 or 3849704 - probably 3849704)

Well, maybe not. The small spring is 4" long, and the original is 4.25". You can stretch this one out, meaning it's not real heavy duty. Will it work? can't say for sure.

I read where "just go to the hardware store, find something similar". Don't know where they're shopping, but Blows and Cloan Depot don't seem to carry springs with hooks on the ends.

I was just at my local ace hardware store and saw a row of those type of spring not shure on size but I would try small local store around town.. im not shure if there's a Tacoma screw or a fasteners but I would give them a shot.
