I have ran my undercar lines with the intention of running a 1/4 vent line from the top of the radiator to the coolant tank in the rear. Before I do I would like to throw what I was thinking out there.
I was thinking of running 1/4 stainless the length of the vehicle the same routing holes as the brake and clutch lines. I know Brake fluid gets much hotter than coolant so my though is to seperate the coolant line with split sections of hose (like the oe brake and clutch line were)
My questions are; Do you foresee an issue with my routing plan? Is 1/4 large enough? How did you run this line?
