Detailed Product Description

This Motorad High Flow thermostat, part number 2028-195, is designed to regulate coolant flow by opening at 195 degrees Fahrenheit, ensuring the engine reaches and maintains the correct operating temperature.

The built-in jiggle pin weep hole allows trapped air to escape, preventing airlock and promoting consistent coolant circulation. The bypass diameter of 1.09 inches and length of 1.40 inches facilitate proper coolant flow during thermostat closure, reducing engine warm-up time and improving heater performance.

Installation Notes and Tips

Before installation, ensure the cooling system is fully drained and the housing surface is clean and free of old gasket material. This thermostat does not include a gasket or seal, so a compatible gasket must be sourced separately. The jiggle pin weep hole should be oriented at the highest point to allow air to escape. No special installation tools are included, so standard hand tools are sufficient. Verify the thermostat opens at 195°F to match engine specifications.
