2002 XJ8 Radiator Cap - replacement
#1
![Default](/forum/images/icons/icon1.gif)
Hello everyone. I'm new to the forums and have had my XJ8 for a little over two years.
This past summer I've noticed a leak from the radiator cap and I need to find replacement. Only problem is that I'm not sure it is called a radiator cap. It is a plastic cap, located at the front/top of the engine - see attached pic. I can't find a replacement.... lettering on it is: PA66-GF30, W584A, and 96JV-8A511-AC.

I took it to a local shop (non-Jaguar) and their cost to replace was pretty high (over $100). I would appreciate any help in knowing what this is called and where I can buy a replacement.
Thanks for your help.

The cap is part of the housing and I am not aware that it is sold separately. Not a bad idea to replace the housing and cap with an aluminum one anyway as they are famous for leaking. Housing and cap in aluminum is about $70 available from several Jaguar parts on-line sources.

I recommend Welsh Enterprises for buying the aluminum thermostat housing kit (thermostat is included with kit):

Motorcars LTD price for the thermostat is almost $46 plus another $60 for the thermostat housing plus $11 shipping UPS 3 -5 business days. Total is $117.
I have nothing against Motorcars LTD, I think they are good.
But Welsh is just as good and a better deal at about $81 total - a difference of $36.

You might want to replace some of the cooling hoses while you are replacing the thermostat components.
You can save about 50% by buying the hoses from Rock Auto Parts.com.
There are 3 hoses you should consider replacing:
ÜRO PARTS Part # MNC4505AD Radiator Coolant Hose, Upper
ÜRO PARTS Part # MNC4515AD Radiator Coolant Hose, Lower
ÜRO PARTS Part # NCA2213AC Coolant By-Pass -- Hose Bypass Hose From Thermostat Housing
The 3 hoses cost $37.44 plus $9.70 shipping at Rock Auto and over $100 at most of the other auto parts places.
