so i removed my all of my a/c,heat,and ventilation system from my del sol, its going to be my summer only car so i have no need for all of that, anyway i'm not sure what to do with my coolant lines that ran into the heater core. do i just loop the lines so it just flows back through the system since there's no heater core?

 

loop them or you can cap them at the head and the back of the block......
capping it makes it look cleaner.
but looping it keaps the coolant flowing better

 

Just loop the lines.

 

thanks guys, i was pretty sure i could just loop them but just wanted to double check.
i'd deff feel more comfortable with looping rather than just capping them due to coolant flow, and pressure blowing the caps off.

 

when your heater core is set to the full cool position then there is a valve inside that completely closes.
they are used to being "capped" there is not really any reason to loop them.
pressure won't blow the caps off.

 

^true. i had mine capped and i had a turbo and beat it up...with no problem at all.
