    TB coolant line questions

    I am putting a new 101mm ls2 style TB on my intake and I was wondering how I am suppose to cap off the coolant lines that went into the bottom of the stock TB? I have a few ideas but I am unsure if they will work.

    It's the the one from the radiator or the one that comes from under the intake. The stock TB had provisions for them but this TB doesn't. Is it ok to cap them off? I'll get a picture up to show what I am talking about.

    the TB does not need coolant flow thru it.......so it is OK to bypass it.....is that what you were asking?

    This.

    The line coming from under the intake is the steam vents for the heads...you need these. Run a rubber line from under the intake to the top of the rad.

    go to your parts store and get vacuum caps. they work fine. secure them with zipties or the coolant pressure will eventually push them off causing you to loose a lot of coolant. ask me how i know.
