Heater core hoses....

As you guys know (from my stupid posts sometimes) the greenest of newbie's. But you guys always have the answers to my problems.

Has anybody got a pic or can describe where the heater hoses run to from the core? when i bought my car the core was not hooked up and i'm scared i'll reverse the hoses without a clear idea where they run.

It's startin' to get chilly in Missouri!

Let me see if I can remember how it's done stock. Manifold to throttle body, throttle body to heat diverter widget, heat diverter widget to heater core, then heater core back to radiator.

I bypassed most of that crap. I ran it directly from the manifold to the heater core, from the heater core to the radiator.

I'm not sure if it's the same on all models but on my '92 RS the hose that comes up from the back of the engine is the bottom heater core hose.

Hope that helps.
