Detailed Description

Motorad 243-195 is a Standard engine coolant thermostat engineered for vehicles that require a 195F thermostat and OE-style sealing. The copper case and wax compound support quick reaction to coolant temperature shifts, helping the cooling system maintain the intended operating range. The offset design and air relief valve support proper coolant flow and installation alignment where specified by the application.

This thermostat cross-references BBB Industries 13889 and CSF 3889 for the same application. It is a direct replacement choice for 1987-1991 Chevrolet Cavalier, 1987-1991 Chevrolet Corsica, 1987-1991 Pontiac Tempest, 1987-1989 Buick Skyhawk, and 1987-1988 Oldsmobile Firenza applications that call for a 195F thermostat with OE-specified thermostat and seal.

What It Helps Address

• Engine running cooler or hotter than the specified operating range
• Delayed coolant temperature regulation after startup
• Thermostat replacement during cooling system service
• Temperature control issues caused by worn internal thermostat components
• Seal-related leakage at the thermostat housing interface

Installation Notes and Tips

Verify the required opening temperature, seal style, and housing dimensions before installation. This part uses an O-ring seal and does not include an installation tool. Clean the thermostat housing and sealing surfaces thoroughly, then install the thermostat in the correct orientation for the application. Confirm that the bypass dimensions and flange measurements match the original part before assembly.
