red top sr question

[driftiteasy0113]

hey guys i am new to the sr, i was wondering what the deal is with these little tubes coming from the heater core inlet and outlet pipe. can i block off these little pipes that go to the iac or whatever valve that is? does that valve have to have coolant running to it or can they just be plugged?any answers help,thanks

You can bypass your IACV, just that your cold idle is going to be the same as your warm idle. Also, if you start to overheat your motor won't idle up, but if you don't have the clutch fan this is a mute point.

You can also eliminate the hose that runs through the throttle body. That hose always annoyed me
