I’m going to replace all the factory coolant lines. I’m using this opportunity to revamp a lot of the engine bay
But I’m worried about heat soak What options are out there to upgrade the intercooler/radiator who has them and what’s the best pricing for available for a 16 XJR ?

Won’t new aluminum/metal cooling lines create additional heat soak issues ?

 

Keep digging! Consider upgrading the IC pump too. We have a guy doing a great bit of work on a killer chiller setup. Maybe take a look at what he is doing?

A simple search is worthwhile too?
Here are 26 threads on that subject? Work you way thru them and make a plan of attack first.
I have a upgraded IC and IC pump so far at least!
