Frequently asked questions

What is the AJ811793 water outlet pipe for?
The AJ811793 water outlet pipe mounts at the thermostat housing outlet and carries coolant away from the thermostat into the cooling system once it opens. It's fitted to naturally aspirated Jaguar V8 petrol engines as part of the cooling circuit.
Which Jaguars does the AJ811793 pipe fit?
The AJ811793 fits naturally aspirated V8 petrol Jaguars: S-Type (1999-2008, 4.2L, from VIN M45255), XF (2009-2015, 4.2L), XJ (2003-2009, 3.5/4.2L, VIN G00442 to H32732) and XK (2006-2014, 3.5/4.2L, from VIN B00379). Check your VIN on the ranges given.
Why replace the thermostat water outlet pipe?
These outlet pipes carry hot coolant under pressure at the thermostat housing, so they can corrode, crack or leak with age and heat cycling. A weeping pipe risks coolant loss and overheating, so a sound outlet pipe matters for keeping the cooling circuit sealed.
