Performance Water Pump & Thermostat Kit for Jaguar XE (2017-2019) 3.0L

Upgraded Performance Water Pump & Thermostat Kit for 2017-2019 Jaguar XE (X760)

What it Does: The Performance Water Pump & Thermostat Cooling Kit replaces vulnerable factory plastic cooling components on the 2017-2019 Jaguar XE to eliminate common coolant leaks, stabilize operating temperatures, and prevent catastrophic engine overheating.

The Stock Jaguar XE Cooling System Weakness

The factory cooling assembly on the X760 XE equipped with the 3.0L supercharged AJ126 engine is notorious for premature failure due to heat-degraded, friction-welded plastic coolant crossover pipes and thermostat housings. Under constant thermal cycling and elevated operating pressures, these OEM composite conduits turn brittle, developing hairline cracks along molded seam lines and at the valley tube junctions. Failure to address weeping seams leads to sudden depressurization, rapid coolant evacuation, and severe risk of thermal distortion to the aluminum block and cylinder heads.

The Engineering Solution

This comprehensive cooling package replaces brittle OEM plastic with heavy-duty cast and machined aluminum coolant crossover pipes, delivering permanent structural resilience against extreme thermal cycling. The kit pairs an OE-specification high-flow mechanical water pump with a precision-calibrated thermostat and integrated temperature sensor to maintain precise ECU-monitored operating ranges. Corrosion-resistant copper bleeder screws and reinforced brass/copper-fitted hoses eliminate the risk of sheared plastic bleeders during service, preventing air locks within the cooling and supercharger intercooler circuits.

Frequently Asked Questions & Fitment Warnings

Does this fit the X760 XE?

Yes, this is a direct fit for the 2017-2019 Jaguar XE equipped with the AJ126 3.0L supercharged engine. Does not fit naturally aspirated engines.

Do I need to bleed the cooling system after installing this kit?

Yes, a vacuum-assisted refill followed by bleeding via the included copper bleed screw is strictly required to prevent air locks in the supercharger cooling jackets.
