    I’m finishing up a EGR delete. What do I do with the coolant lines?

    Do I run them back through the iac valve? Or cap them off??

    It seems like most people are capping the off which doesn’t make sense because it was going through egr valve and from there into the aci valve and back to the engine!?

    Yep, get a coupler or something you can use as a coupler between those two hoses that go in and come out of the throttle body like the mechanic above stated:D

    The coolant runs into the bottom of the IAC valve and out the other side. It’s just a small loop off the main coolant line.

    So after deleting the EGR valve I recreated that loop. Instead of running the coolant Through the EGR I ran it straight to the IAC valve.

    You can also hook the lines together, or cap them off, But than your bypassing the IAC valve.
