That is correct. But, I just went out and checked under the hood of the wife's X and they were hooked up like this:

The back of the engine, where both hoses come out from, the upper hose goes to the upper heater core connector. The bottom one, goes to the bottom.

So yeah, they can go on either way, but that's how they're properly hooked up.

Glad to have you aboard rjac! Stick around, there's a bunch of us out here. Several Texas folks as well.

Longhorns fan?
