Antifreeze Leaks
I have a 2002 Impala with 3.8 engine that is leaking antifreeze at the throttle body connection to the plentlum. Do you think that changing the gasket will stop the leak or will it need a new plentlum? Also when I change the gasket would I need to use extra red silicone on the surface? The leak is just a small amount, about a pint per month.

If in deed it is the gasket, change it and just use gasket dressing. Be sure to clean all of the old gasket off.
Have you tried to tighten the bolts/nuts first?

If, in fact, your Impala has a Buick motor in it.........and the intake plenum is plastic..........They DO have a tendency to split/crack .........They're not TOO expensive if i remember right......so take a GOOD look when you get it off.........
If it's a 3.4 it's probably another case of Intake Gasketitis

leaky 3.8
It comes as a plenum set and they are not that expensive and they do not use any type of sealer for the gaskets the gaskets are a o-ring style so it is just a torque thing no sealer. Replace the whole thing it is the easiest and the best way to do so.

Antifreeze leak
Yes I checked the bolts and they are tight. It is the same engine as a 97 Buick that I once owned, and it leaks a small amount of antifreeze also. I plan to remove the throttle body soon, but not the plentlum, if that is possible. Is that possible? The plenlum is made of plastic and the local Carquest has it in stock. How do I remove the injector lines?
