(s1) viscous clutch type

dears,

buyed but isn’t correct , i have no space between pulley and radiator fot this new type.
s1 2.8 '69 , what’s correct code for my engine ?

viscous%20fan%201

viscous%20fan%202

Fred,

most times it is helpful to just consult the Parts Catalogue which you’ll find at https://www.jaguarclassicparts.com/uk/older-vehicle-info. You look at <XJ6 Ser 1> at and find C.28018 for non AC cars and RTC 1002 for AC cars. The parts catalogue doesn’t distinguish 4.2 and 2.8 litre engines with respect to viscous clutches.

The S1 XJ VC is the same as 420/late MKX/420G

It might be possible to get that later VC fitted, but the space between rad and fan is about 5mm, and would also need rad moving forward to be able to initially fit it over the studs

A viscous coupler can also be remanafactured by a specialist
