MotoRad 226-195

MotoRad 226-195 is a standard engine-coolant thermostat beginning to open at 195°F / 90.56°C. It includes a lower bypass flange for cooling systems requiring bypass-style thermostat construction.

Application / fitment

The thermostat is catalogued primarily for selected classic Cadillac and certain heavy-duty vehicles. Correct fitment depends on main flange diameter, lower bypass dimensions and required operating temperature.

• selected Cadillac Calais, DeVille, Fleetwood, Eldorado and Commercial Chassis
• selected Cadillac 368, 425, 472 and 500 CID engines depending on year and housing
• approximate Cadillac range: late 1960s through the mid-1980s
• selected heavy International applications after catalogue verification

Do not substitute a lower-temperature thermostat without considering engine calibration and cooling-system design. Incorrect bypass-flange dimensions can prevent correct coolant circulation.
