i am trying to remove as much weight as possible.

i am trying to remove the heater box from the car, i got the screws/bolts removed from the frame of it but...

what are the 2 lines going into the back ? how can they be removed OR how can i leave then and remove the box inself ?

got into a job a little to big, i thought i could just unbolt the box and remove it.

thanks for any info !

Is your car or did your car have A/C?

If so those 2 lines you are referring to ar your A/C refrigerant lines.

If NO A/C then those 2 lines are the connections to the heater core.

Yes, you can remove the lines from the core and remove it.

Then you need to block off or re-route the hoses in the engine bay that used to connect to the heater core.

You will see the two hoses coming out of the fire wall in this picture. One of my hoses has the Temperature gauge hooked into it. (I did a little custom work to be able to use an aftermarket gauge).

After you disconnect these hoses, you can cut them and hook them together using 2 hose clamps and a small brass nipple from a hardware store.

:D

I wouldn't block them off, I think they act as a bypass to allow coolant to circulate when the thermostat is closed. Connecting them together is fine.

I wouldn't block them off either. I would re-route/connect them together.

DONT DO THIS! (search for my overheating thread for the full story). Basically just connecting the hoses together creates a low resistance path for the coolant, which results in poor circulation through the cooling jacket of the engine. End result is overheating. Plugging the lines is 100% ok, as is connecting the hoses while inserting some type of restrictor.

OK, I won't do it. I'm looking at the diagram right now. Wouldn't too much flow in the heater circuit result in poor circulation through the radiator, not the jacket? Same result anyway... :?

Sorry, yes, that's what I should've written... same difference.
