your right no heat, and it doesnt screw anything else up with the car as far as i know.

if you know where the heater core is i guess oyu can just take the two hoses going to it and connect them together with a pipe of the same size as the heater core pipes.

You notice that black thing on your passenger Valve cover......that's the heater valve.... You can remove that whole thing.....

I would recommend looking into a manual to find the coolant flow.....You can actually remove ALOT of coolant lines that have no purpose except for the heater.....

Once you do this you will have 2 holes in the firewall where the heater core is or was......

Just a thought--the person i got my car from removed the heater hoses. only problem on cooler nights the window would fog up and no defroster in the front to clear it. --if you have a tpi car you can run a hose from the lower intake and by pass the plenum to the radiator heater in. seems silly though not to have heater--unless your core is leaking.

you just take the long hose from the water pump and stick it onto the nipple at the back of the intake..that's it! no need to splice the two hoses together.

Or just plug it at the intake and plug it at the radiator and either remove all the other crap or just leave it there. Screwing around at the heater core is a lot harder than just plugging the lines at the source and it reduces the chances of leaking because the plugs are less leak prone than clamped fittings, plus you have 10' less heater hose to worry about.
