My 2000 XKR leaked all the coolant from the reservoir/overflow tank out the back and I think the rear hoses or valve(s) are the issue.

The shop lists the R&R as a 5 hour job?

Anyone do one and know what it entails?

 

Depends on exactly what is ncluded in those five hours, what hoses and valves. But on a Xkr it's not an easy job, so five hrs doesn't sound that much to me

 

First you must trace the leak, could be the reservoir itself or something easy to fix..
