VAICO Engine Coolant Thermostat Housing

The VAICO engine coolant thermostat housing (also called a thermostat housing, coolant flange or coolant outlet housing) holds the thermostat in the cooling system. It also gives the coolant a sealed path between the engine and the radiator. A sound housing helps the engine reach operating temperature and hold it steady.

Key Features:

• Made as a direct replacement for the original thermostat housing
• Built to hold up under repeated heat cycles and constant coolant exposure
• Machined mating surfaces and precise port geometry help the housing seal and keep coolant flowing
• Many versions include integrated connections for coolant hoses and sensors, as on the original part
• Made by VAICO, a brand of VIEROL AG, which supplies the European automotive aftermarket with parts built to OE-matching specifications

A cracked, warped or leaking housing can cause coolant loss, overheating and poor heater performance. Replacing it with a quality part helps restore reliable cooling system operation. Replace the gaskets or seals and top up the coolant whenever you service the housing.
