Installation Notes and Tips

Verify the 198 degree temperature specification and compare flange and bypass dimensions before installation. This thermostat excludes the housing, so confirm your vehicle uses a separate thermostat service setup before ordering. Clean the sealing surfaces and inspect the cooling system for contamination or gasket damage during replacement.

For fitment verification, use the vehicle year, make, and model exactly as listed for Saturn L300, Cadillac CTS, Saab 9-5, and related applications. The part number 48759 should be matched to the OE temperature requirement and housing configuration before installation.
