- Delayed coolant flow regulation in OE-specified Jaguar cooling systems
Installation Notes
Verify the 192 degree F specification before installation and confirm the housing orientation matches the vehicle layout. This assembly does not include bolts, gasket or seal, or mounting hardware, so reuse or replacement of related service parts should be planned separately. Follow the vehicle service procedure for coolant draining, air bleeding, and refill to reduce the chance of trapped air after installation.
