45 Degree Polished Aluminum Waterneck

Fits Chevy 4.3L V6 and Chevy V8 Engines

45 Degree Outlet Angle for Hose Routing Clearance

Polished Aluminum Finish

Replaces the Factory Thermostat Housing

The angle is the whole point of a waterneck like this. A 45 degree outlet lets the upper radiator hose leave the intake on a gentler sweep, which matters when a taller manifold, a big carburetor or an aftermarket air cleaner has pushed the hose into a hard bend. Polished aluminum also holds up better than a rusting cast housing under the hood of a finished car.
