90 Prelude Si Leaking coolant

My little Prelude is leaking coolant from a sensor or something that is bolted on the front of the intake plentium. It has 2 bolts that go through it and one electrical connection. Then it has 2 small coolant hoses going to it. I took it off and there is a plate on it and a cavity inside the plate. It looks like the coolant is just running through it for the heat? Anyway, there is a gasket that is all messed up on that and I don't know what I'm looking at to order a new one. Can I get just the gasket? or do I have to buy that whole part? I'm figuring it has something to do with idling because of the holes in the intake where it bolts on. It leaks antifreeze down all around the intake and smells alful.

Yes-you should be able to get just the gasket. Just go to honda and they will have a picture of the whole assembly. Make sure you clean off both surfaces before you put the new gasket on or else it will still leak. Use a wire brush and sand off each surface.
