Coolant Specification Change –
Coolant D542 (Yellow)
A revised coolant, Jaguar D542, which is yellow, has entered XK8 production from VIN 010343.
Use only yellow Jaguar D542 coolant when topping up the coolant level on any XK8 from VIN
010343-on, as well as on any vehicle that has been converted to D542. Dilute the new coolant
with an equal volume of clean water.
XK8 vehicles in the VIN range 001001-010342 were originally filled in production with Jaguar
coolant D985 which is blue-green in color. Vehicles in VIN range 001036-010342 are covered
by Service Action S813 which requires flushing out the earlier coolant and replacing it with
D542. Vehicles which have been converted can be recognized by the yellow coolant color and a
label (part no. MNA 7698AA) on the coolant reservoir.
Vehicles factory-filled with D542 (from VIN 010343-on) do not have the coolant reservoir
