LS Steam Vents

[TurboTerry87gn]

For thoes of you who have swapped in an LS motor and are not using a surge tank, where did you plumb in the steam vent lines and did you leave the 2 rear capped or tie them in too?
I planned on tying them into the upper radiator hose about half way between the outlet and the radiator, but I have also been thinking about bringing the radiator to a radiator shop and having a nipple soldered into the passenger side tank where the pressure is lower.

Tap them into the highest point in the coolant system. I did not cap the rear vents on mine.

I did mine right on top of the water pump

I used the Kurt Urban set up and returned the top line to the top of the radiator.

I installed a cheap Champion radiator in my car which had a 1/8npt plug installed under the overflow tank hose. I hooked mine to there and 2000miles later I have no cooling issues and run rock solid 180 driving and 210 in traffic with fans on.
