Throttle body plate

[3504v]

Hi everyone first post, but have been lurking for sometime now. I just got one of the LT5 TB plates (looks great, he really does a nice job on them) before I pull the old one off, I better find out what is under it. Will I have coolant spilling out or a spring popping up. Will it need a gasket, or can I simply take the old one off and put the new one on. Thanks in advance, Jim

Hi Jim, There would be a bit of a coolant mess I would think. Don't know for sure as the only time I had my plate off was on a plenum pull. Nothing under there but a gasket and the coolant....should be no surprises hidden under it except for maybe some of that electrolysis corrosion maybe. I had a white color scale inside the chamber that I washed off with a toothbrush & as I had that electrolysis thing happening I had to clean up the gasket flange & a few screws and the plate. I think minerals in the water contribute to the crud. I guess it's worth it to try to use as much distilled water as possible when the collant is r&r'ed. I know my gasket didn't look to be re-usable, I had new gaskets so I took no chances. I can't say for sure that I could not re-use my old plate gasket though.

Drain a little bit of coolant out of the radiator to drop the level some. Then you can remove the top plate with no worries.

Gasket will be worthless. It will rip and shred when you pull your old one up.

I wish I could install my throttle body plate but, there is just no way I can get my old one off without ruining it & or the plenum, I tried twice. It is fused to the plenum.

Hey Bob
Maybe instead of trying to pry the plate off, you could thread a couple of
larger bolts into the bolt holes of the plate and tap it off. I bet once the
"seal" is broken it'll come off. You will need to get the old gasket off........
Good luck!
