Product Details

The Motorad Standard line focuses on OE-style cooling system service parts built to match factory requirements. Part number 335-180 is an engine coolant thermostat with a 180°F opening temperature, designed for vehicles that rely on stable coolant flow control to maintain proper operating temperature. The jiggle pin weep hole helps purge trapped air during filling and service, while the copper case and wax element support fast response as coolant temperature rises and falls. This part cross-references Stant 48588 and Four Seasons 33580 for the same application.

Fits 2006-2013 Dodge Attitude, N/A; Fits 2012-2013 Kia Forte5, N/A; Fits 2009-2010 Kia Magentis, N/A; Fits 2004-2006 Dodge Verna, N/A; Fits 1995-1999 Hyundai Accent, N/A.

Common Cooling System Issues

• Engine running cooler or hotter than expected
• Slow warm-up after cold starts
• Temperature fluctuation during stop-and-go driving
• Restricted coolant flow from a worn thermostat
• Air trapped in the cooling system after service

Installation Notes

Verify the 180°F temperature rating and compare the thermostat dimensions to the original part before installation. Clean the housing sealing surfaces thoroughly and inspect the cooling system for contamination, corrosion, or damaged seals. Because no gasket or seal is included, reuse or replace the sealing components as required by the application. Bleed air from the system after refill to help prevent temperature spikes.
