so I take my car into the GM dealer for it's annual service & inspection, tech finds a bunch of things to fix, I'll cover them one at a time, first is the coolant mainfold to intake manifold. I didn't even know this existed until the tech pointed it out, it's a small plate hidden under the throttle body attached to the back of the intake manifold, it was damp with coolant, tech recommended replacing gasket, also since must remove throttle body to gain access, bought that gasket too before starting job
drain some coolant -
remove throttle body -
gasket not in greatest shape, looks like leaking coolant both ways, to outside and into intake -
manifold plate removed -
cleaned up and ready to put back together -
back together, just need to install intake hose -
