Nightmare Over? Jaguar XJS V12 Radiator Swap – Epic Job Recap + Pro Tips

Sorry for the thumbnail and title there - very dramatic huh? But really I'm wanting to convey being proud to have this job done and also finally have this video done (recorded on Jan 6, 2026 - and for that matter, this job started April of 2025!). Lots of things happened in life that blocked progress, and there were some mechanical setbacks and also some scope creep - as usual! The point of this video though is to wrap up and share all that was done to refresh the cooling system, replace the oil cooler/hoses, install and fit the Wizard Cooling radiator, flush the system, and deal with a dreaded issue with an oil airlock in the oil pump. Oh and I tossed on some throttle linkage bushings too! Check back here soon and in comments I will add chapters and relevant links as we go along.
