Detailed Product Overview

Motorad part number 233-180 is an engine coolant thermostat designed to regulate coolant flow as engine temperature rises. The copper case and wax element help the thermostat react promptly to temperature changes, while the OEM-spec construction supports consistent operation in demanding automotive cooling systems. Dimensions include a 2.12 in sealing flange outside diameter, 1.4 in height between flanges, 2.00 in overall height, 0.06 in flange thickness, and bypass dimensions of 1.14 in diameter and 1.22 in length.

This thermostat is a practical replacement for vehicles that require a 180 degree thermostat and OE-style cooling control. It cross-references Gates 23380 and Anchor 3048 for the same application. Use 233-180 when servicing cooling systems on Nissan and Mitsubishi models that specify this temperature range and thermostat style.

Common Cooling Issues It Can Address

• Engine running hotter than normal due to a thermostat that no longer opens correctly
• Slow warm-up or unstable operating temperature from worn thermostat internals
• Coolant flow problems caused by a sticking or inaccurate thermostat
• Temperature fluctuations during stop-and-go driving or highway use
• Cooling system service needs on vehicles requiring a 180 degree thermostat

Installation Notes and Tips

Install the thermostat with the correct orientation for the housing and coolant passage layout. Inspect the thermostat housing, sealing surfaces, and coolant condition before assembly, and replace any damaged gasket or seal components as needed since a gasket or seal is not included. Verify the bypass dimensions and housing fit before installation, and bleed air from the cooling system after refill to help prevent trapped air from affecting temperature control.

Quality Assurance
