Overview
Give your LB7 Duramax a clean, upgraded look with PPE's Polished 304 Stainless Steel Thermostat Housing Cover. This direct bolt-on replacement is a durable, corrosion-resistant alternative to the factory cover, which is known to rust over time.
Premium Stainless Steel Construction
The housing is cast from high-strength 304 stainless steel and finished with a polished surface for added style under the hood. The material offers excellent resistance to rust, coolant exposure, and long-term wear.
Integrated Bleeder Screw for Easy Air Removal
PPE includes a black anodized aluminum bleeder screw (P/N 513081100) featuring a built-in air channel and a Viton O-ring. This design allows you to quickly purge trapped air from the cooling system - just loosen, bleed, and tighten.
