Product Details

Motorad UltraStat thermostats are engineered for stable coolant flow regulation in everyday driving and repair work. Part number 5474-180 is a 180°F engine coolant thermostat for vehicles that call for this temperature range, including Chevrolet Cavalier, Pontiac Sunfire, Oldsmobile Alero, Pontiac Grand Am, Chevrolet Malibu, Buick Skylark, and Oldsmobile Achieva applications listed below. This part cross-references Four Seasons 45028 for the same application.

What This Thermostat Helps Address

  • Engine running too cool or taking too long to reach operating temperature
  • Temperature fluctuation caused by a worn thermostat
  • Cooling system stress from abrupt temperature changes
  • Corrosion-related thermostat wear in the housing area
  • OE replacement needs for 180°F thermostat service

Installation Notes

Verify the thermostat temperature rating and sealing flange dimensions before installation. Because no gasket or seal is included, reuse only if serviceable or replace with the correct sealing component for the application. Confirm housing condition, coolant quality, and mating surfaces during service. Part number 5474-180 is listed for N/A position applications.

Quality Assurance
