Changing thermostat on L67

[Blueglow]

Car has been having overheating problems lately, put it down to the thermostat.
Heard its a bit of a big job, where abouts is the throttle body located on the L67?

And do i need to take anything else off to get to it? I'm going to be changing the supercharger coupling since it is rattling like a nightmare, so that will be out of the way

Its make it alot easier if you remove the rear intake elbow into the back of the supercharger along with the throttle body. Its not a very big job just fiddly. The thermostat has a funny black oring around it unlike the std ecotec too.
