I know that this has been asked a million times, but everyone tells me something different, so i'm confused. I'm getting ready to run them but I can't decide if I should run it off the throttle body or the heater core line. If I run it off the heater core line, it's bigger, and I can run my return line to the line coming out of the heater core. Just tell me what you did and i'll decide from there. no need to flame, I already feel stupid enough

 

yeah, runnin them to the TB sounds like a bad idea if you ask me, but everyone seems to do it, just tee off the heater core lines.

this is what I'm doing, I'm gona run mine coolant lines to the TB line, but have 2 valves to keep the coolant from going to the TB in the summer, but in the winter, the long canadian winters, i can just open the valves and let it flow to the TB
