im going with the HSR and have an aftermaret radiator without a fitting to mount the heater hose to.

i want to get rid of the heater control valve since i have no a/c anymore but i need to know which fitting on the heater core to connect the heater hose from the intake manifold to and which fitting takes the hose from the water pump. (basically the left heater core fitting goes to where?)

i didnt want to run my hoses to the intake and waterpump but i cant get around it now.

i know vader said something about a standard heater hose not being able to take the heat headers put out (thats why there is a hard line on the pass side frame rail) but can it be done...has ANYONE run the hoses like this. id like to delete the hard line if possible.

 

Run the larger (3/4") tube from the heater core to the water pump. The smaller (5/8") tube should be fed from the manifold.

Reason being, is you want the return line to be the larger of the two, so as not to build too much pressure in the heater core under high RPMs.

FWIW, 1LE cars had a single hardline, without the "T" nonsense like for the valve. Also, some V6 cars had dual hard lines, without any heater control valve. I've found those parts to be useful for plumbing around headers -- but hose WILL work, if you're careful with the routing. I ran plain hose with headers for years, before switching to hard tube to get the hoses out of sight.

 

thanks man. i wanted to run all hose just to clean things up a bit but now ill be on the look out at the junkyard for those hard lines.
i just dont know how i plan to run the hoses around the headers just yet.
