Free mod! Throttle body coolant bypassThe EVAP tube, PCV line grounding strap, and EGR valve are connected. Rather than route the coolant hose that comes off the front bypass hose to the throttle body, a brass connector with barbed ends is inserted into the line, and after slipping on two factory hose clamps, the other end of the throttle body coolant line is attached and tightened. The throttle-body coolant bypass mod was just completed. This procedure is the same on an LS1 intake, so if you don't need the extra heat that might keep your throttle body from icing up in the winter months, this modification may take you five minutes with a cool engine. Using a large crescent wrench, the EGR tube is connected to the LS6 EGR fitting that we installed earlier. The stock throttle body is then reinstalled with the three 10mm bolts, and the PCV hose was connected to it (not connected in picture). View Related Article
