Detailed Description

This Calorstat thermostat housing assembly is used in cooling systems that rely on a 90 C / 194 F opening temperature to regulate engine operating temperature. It is listed for multiple Volvo platforms, including XC60, XC90, S60, V60, S80, XC70, V70, and S90, as well as the 2008-2012 Land Rover LR2. If you are searching for a Volvo XC60 thermostat housing assembly or a Volvo XC90 coolant thermostat housing replacement, TH7154.90J matches the specified application data and temperature rating.

This part cross-references Continental 49449 and Gates 34716 for the same application. The housing is made from plastic and uses a gasket seal to support a secure coolant connection at the mounting surface.

What It Helps Address

• Coolant temperature that stays too low or takes too long to reach operating range
• Thermostat housing leaks at the gasket interface
• Cracked or warped plastic housing surfaces
• Faulty coolant flow control in the engine cooling circuit
• Temperature regulation concerns on Volvo and Land Rover cooling systems

Installation Notes and Tips

Verify the opening temperature, outlet port layout, and mounting hole count before installation. Inspect the mating surfaces, flush contaminated coolant if needed, and replace any damaged seals or hoses connected to the housing. Confirm fitment by year, make, and model for Volvo XC60, XC90, S60, V60, S80, XC70, V70, S90, and Land Rover LR2 applications before service.
