Our ZZP 3800 Billet Thermostat Housing is a great bolt in replacement for your factory thermostat housing. The factory cast unit gets pitted and degrades over time from dexcool; this often leads to sealing problems, even with a new gasket. Made of billet aluminum our thermostat housing will not warp or rust, and will always look great in your engine bay. Available in two finishes, clear aluminum or matte black anodized. Uses the stock style thermostat housing gasket. Comes with 1/8" NPT plug on top, compatible with your stock bleeder fitting. Includes M8 stainless bolts.
Fits Series II and Series III 3800 engines in FWD configuration. We have not confirmed fitment on F-Body 3800's.
Body thread is "1"-18 straight thread.
Made in house here at ZZP in Wyoming, MI on our CNC mill and lathe.
