Detailed Description

The heavy-gauge stainless steel body and copper components improve resistance to corrosion, while the spring design helps the thermostat respond consistently as coolant temperature changes. The offset reverse poppet layout supports proper coolant flow control in the applications listed, including Mazda Miata, Kia Sportage, and Toyota Pickup.

This thermostat is a practical replacement choice for cooling system service on older and newer vehicles across the fitment range. It is listed for 605 vehicle applications and covers model years from 1967 through 2005.

What It Helps Address

• Engine running too cool or too warm due to thermostat wear
• Slow warm-up after cold starts
• Temperature fluctuation from a weak thermostat spring
• Corrosion-related thermostat housing or valve deterioration
• Air trapped in the cooling system after service

Installation Notes and Tips

Install the thermostat with the jiggle pin oriented to allow trapped air to escape during filling. Verify the housing sealing surface is clean and inspect the coolant condition before reassembly. Confirm the replacement matches the required 195 degree opening specification and the OE-style thermostat dimensions for the vehicle.
