I’ve been planning a road trip from the San Francisco Bay Area through Crater Lake and along the Columbia River Gorge. The closer my trip comes, the more tempted I am to drive my XJS. The car is a 92 V12 convertible. How ambitious do you think this is for an otherwise well maintained car and what type of preparations would you make prior to the journey?
Just recently it started throwing the code for the coolant temperature sensor so I am planning to replace that as well as flush the coolant system and do a general fluid and filter service. I am a bit budget conscious, but is there anything else you would consider essential prior to this drive? Any suggestions about spare parts you’d bring? One other piece of information is that while I have started the car regularly, it has only been driven a few hundred miles in the last 2 years.
