Product Details
Gates OE Type Thermostats are built to provide precise temperature control and an OEM-equivalent fit. This thermostat uses a bottom by-pass configuration, a single jiggle pin/check valve, and an O-ring seal to support consistent coolant flow management in the engine cooling system. The Gates 33948 thermostat is listed for multiple Jaguar platforms, including 2009-2010 Jaguar XF, 1998-2009 Jaguar XJR, 2000-2008 Jaguar S-Type, and 1997-2002 Jaguar XK8, along with select Ford Thunderbird and Lincoln LS applications. This part cross-references Motorad 463-183 for the same application.
Common Cooling System Issues It Can Address
- Engine running too cool or too hot due to thermostat wear
- Delayed warm-up and unstable operating temperature
- Coolant seepage at the thermostat seal area
- Temperature fluctuation caused by a sticking thermostat
- Air pockets in the cooling system after service
Installation Notes and Tips
Verify the vehicle’s thermostat housing configuration before installation, since several listed applications exclude the housing. Confirm the 183 degree temperature specification and bottom by-pass design match the original part. Clean the sealing surfaces thoroughly, replace degraded coolant as needed, and bleed the cooling system carefully using the jiggle pin weep hole to help release trapped air. This part does not include an installation tool.
