The Motorad 432-170 is a complete engine coolant thermostat housing assembly engineered to OEM specifications, giving you everything needed for a straightforward cooling system repair in one part number. It combines a copper and stainless steel housing with a mechanical disk-type thermostat that starts to open at 170°F, plus an included rubber O-ring seal so you're not left sourcing a separate gasket. A built-in bleeder hole helps release trapped air during coolant fill-up, while the jiggle pin check valve supports proper air venting during operation. Designed as an original equipment style replacement, this assembly is intended to install like the part it replaces without modification. It's a practical option for owners of applicable 2002-2006 Acura RSX/CSX and Honda Civic/CR-V models with K20 or K24 engines looking to replace a worn or failing thermostat housing with a single, seal-included assembly.

- Integrated rubber O-ring seal included, so there's no need to hunt down a separate gasket for installation

- Jiggle pin check valve supports consistent air venting for reliable thermostat operation over time
- Copper, stainless steel, and plastic construction built to OEM specifications for a proper housing fit
