Product Details

Motorad Standard part number 216-180 is an engine coolant thermostat for Volvo models that require a 180°F calibration. The copper case and wax element are engineered for fast, repeatable movement as coolant temperature changes, helping the engine reach and maintain its operating range. The offset layout, air relief valve, and OEM-style sealing features support proper fitment in the listed Volvo cooling applications. This part cross-references BBB Industries 13918 and CSF 3918 for the same application.

What It Helps Address

• Engine running too cool or taking too long to warm up
• Temperature swings caused by a worn thermostat
• Coolant flow control issues in the thermostat housing
• Air trapped in the cooling system after service
• Inconsistent heater performance tied to engine temperature

Installation Notes

Verify the thermostat opening temperature and dimensions against the original part before installation. The jiggle pin weep hole should be oriented to allow air to escape during filling. Because no gasket or seal is included, reuse only if serviceable or replace with the correct sealing component for the application. Confirm housing condition and coolant level after installation, then bleed the system according to Volvo service procedures.

Quality Assurance

Motorad manufactures this thermostat to OEM quality materials and safety standards as an OE supplier, using OEM specifications and processes for consistent cooling-system performance.
