I've been a "light" mechanic for many years, a Jag owner for only 4, and a new member to this forum for only a few months and find it mostly very helpful. A broken pully, belt and resevoir hose led to overheating and an small leak from the therm housing onto the engine block on my 4.0 L XK8. I spent almost an hour trying to attack the two rear 6 mm bolts or remove the intake manifold which seemed so unnecessary if I could just get " the right tools"
After reading all your posts,, I was on my way to a welder when I stopped at a NAPA store. They sell a 8 / 10 mm brake bleader wrench made by Evercraft service tools, which is almost perfect for the job. It did break the rear bolts without modification of the tool and I used a curved long needle nose and a " cut down" 8 mm 1/4 inch drive socket for the rest of the rear bolt removal.
Based on other post info, I was going to re-install with the screw driver slot idea, but thien I found 2 6m - 1.00 x 20 cap screw bolts for the rear, and 2 6m 1.00 25 (same as original length) for the front bolts and installed them very easily with a 5mm ball hex driver 3/8 drive socket,, the ball end give you torque as well as a small angle for easy verticle installation. .... I hope these ideas help others in the future... and now on to fix the neg camber problem

On my two cars the thermostat housing has been replaced on each once under warranty and I replaced one moving to aluminum after a second leak. Pretty good chance that yours is going to fail at some time. Fortunately, the failure is a soft one, slowly showing crusty yellow/orange around the base without catastrophic coolant leaks. That fits well with my philosophy of not fixing anything that is not broke.
I have crusting on my 2005 xk8 4.2 a replacement part is no longer made. I have searched any suggestions .
Thanks
