Polished Aluminum Water Neck Thermostat Housing For 1970-79 Pontiac Firebird Trans Am 400 455

Dress up the engine bay of your classic Pontiac with this polished beauty.

This is a brand new water neck and thermostat housing from RPC, designed specifically for 1970 to 1979 Pontiac Firebirds and Trans Ams, particularly those with the 400 or 455 big block engines.

The part number is R9230.

It's a performance/custom fitment part, meaning it's a direct upgrade for the original stamped steel piece.

The surface finish is fully polished, giving it a mirror-like shine that really pops against a painted engine.

It comes with all the necessary mounting hardware included, so you have everything you need for a straightforward install.

There are no modifications needed—it's a simple bolt-on upgrade.

It's backed by a 90-day manufacturer warranty.
