PPE Polished Stainless Steel Thermostat Housing Cover (2004.5-2010 GM 6.6L Duramax) - (119000543
Overview
The factory thermostat housing cover on 2004.5-2010 GM 6.6L Duramax engines is known to rust over time, which can compromise cooling system reliability. PPE's Polished 304 Stainless Steel Thermostat Housing Cover provides a durable, corrosion-resistant upgrade that enhances both function and appearance under the hood.
Polished 304 Stainless Steel Construction
Crafted from cast 304 stainless steel, this housing cover offers far better protection against rust and coolant contamination than the OEM mild-steel version. The polished finish adds a clean, high-quality look to the engine bay while delivering long-term durability.
Integrated Bleeder Screw for Easy Air Removal
PPE improves serviceability by including a black anodized aluminum bleeder screw featuring a built-in air channel and a Viton O-ring. This design allows you to purge air from the cooling system quickly without removing the entire screw - simply loosen, vent, and tighten.
Direct Bolt-On Replacement
This thermostat housing cover installs using the factory hardware and fits directly in place of the OEM unit. It's a simple upgrade that improves cooling system reliability and eliminates the common rust issues found on stock covers.
