Rein Engine Coolant Thermostat Assembly with Housing

The Rein Engine Coolant Thermostat Assembly with Housing is a replacement engine thermostat (also called a coolant thermostat or thermostat housing kit) that helps regulate engine operating temperature. It opens and closes to control coolant flow between the engine and radiator, so the engine warms up quickly and stays within its intended temperature range.

Key Features:

• Complete assembly that combines the thermostat with its housing for straightforward replacement
• Helps maintain consistent coolant temperature for steady engine performance and efficient operation
• Replaces a worn or sticking thermostat or a leaking or cracked housing, which can cause overheating or poor heater output
• Made as an OE-style replacement part, with attention to fit, finish and function
• Backed by Rein, a brand known for aftermarket replacement parts for European vehicles

Replacing the thermostat and housing together can restore proper cooling system operation and reduce the chance of a repeat repair. Refilling the cooling system with fresh coolant and bleeding it of air is recommended after installation.
