It'* made of a plastic that degrades over time and simply cracks off and such. The replacement pieces are metal. Sometimes it does require the manifold to be removed for this to be done, usually not though.
Pricing is seeming a little high... give him a call and get some better names on what he plans on replacing. There'* not a "kit" that I'm aware of for the S1 motor to swap the plastic upper to metal.
Actually its pot metal, though it has the same disastrous effect.
The upper intake plenum also tends to warp and leak right below the throttle body, but I very highly doubt that'* the case at 62k miles. I bought my 95 Regal with 62k miles and I didn't have a single coolant leak.
I would replace that fitting first. Its right above the water pump. The replacement ones are metal, and these are guaranteed to break. No ifs, ands, or buts, it will break and its likely that it has broken on you. Have a look at that and then come back to let us know if that was it or not.
