Hey guys and gals, I just wanted to share the easy way to get to the rear thermostat bolts on an XK8. They are super accessible once you've completed the right steps.

​​​​​​


​​​​​​​This this is obvious sarcasm for those that are about to jump in and tell me to use a crows foot or something along those lines. I'm tearing everything down to replace it all at once so I'll have many miles of freedom ahead. 😂

 

Hahaha
Instructions unclear, transmission is now on the floor.

All kidding aside, change that thermostat housing for a metal one that won't crack.

 

Yes I'm doing the metal thermostat housing, the valley hoses, the octopus hose, timing chains and tensioners, valve cover gaskets, water pump, all cooling system hoses, and new intake manifold gaskets.

This has kept me busy for a little bit.

 

This little gadget works like a champ!! The tool is used to remove the two rearward 8mm bolts securing the T-Stat housing to the engine block. The front two bolts may be accessed using a ¼” drive and swivel; but the rear two bolts have limited access.

Use Vice Grips - The bent-wrench should be used in conjunction with a needle nose vice grip, and another regular style vice grip twisting the first.

 

If it's not already on your list, change the coolant outlet pipe (AJ85885) while you're in there. Not horrid expensive and you get a shiny new coolant temp. sensor for free...

 

What does it take to bend a wrench that much?

 

You just need to get it cherry red! Decent propane torch should do it.

 

Yep a butane bottle, or even propane, a vise and hammer it over easy.
