This was fun to design got them on just in time for winter storage...




..On a side note.... see that coolant hose, lower left... is it normal to see it collapsed?

 

Hose: replace it. Standard vehicle troubleshooting = defective radiator cap causes this. Not always true on our cars. Ime this is a sign of weak hose. Replaced mine, same thing, months ago. Problem went away. Not too hard to do.

How can you tell if it's a problem with the hose, or the rad cap?
Is there risk of damaging anything to drive it for a while till I can replace it?
Where would you recommend getting the replacement hose from?
Thanks

 

The collapsed hose is caused by a radiator cap problem. As coolant heats up it expands, the cap prevents the resulting internal pressure from venting until a predetermined pressure is reached. (This is done to raise the boiling point of the coolant) After this pressure is reached, excess pressure is vented to atmospher. Inside the cap is a small valve designed to let the air that was vented back in, as the coolant cools and contracts. If this valve sticks closed then a partial vacuum forms in the system causing the hoses to collapse. The proof is to remove the cap, air will rush in and the hoses will expend, although not completely as they will have taken a bit of a set as they collapsed when still warm.
No need to replace the hose, but do replace the radiator cap.

I like the uniqueness and subtlety of the graphics under the hood. Thanks for posting!

 

That's logical - so, if I have to drive it 200 miles to get the part in the spring.. what's the worst case scenario?

Any suggestions on reliable sources for a new cap?

 

Try soaking then washing the cap out under hot water. There is no real problem continuing to drive it until you get a new cap. As for where, I have used Gaudin Jaguar in Las Vegas but I understand the Jaguar part may have declared bankruptcy and Reno Jaguar have taken over that business. (Jaguarlandroverrenoparts.com). There are lots of other online parts companies if you do a search.

Agree on replacing the radiator cap- an easy and cheap fix.

My real question is; where did you get the graphics?
