DIY: TB Coolant Delete

wstar

FWIW, I do currently run a bypass hose like synolimit mentions. I used a length of blue silicon 5/16" hose (from Z1 I think). I did that because I never found a cap solution I was happy with (they would tend to leak over time; there's just no good way to secure a rubber cap against that kind of heat+pressure). But I really don't think there's a flow reason to do so. The tiny amount of flow that goes through the TB lines is insignificant in the big picture, and parallels two other much larger bypasses (the true bypass and the heater core bypass).
