2014-2019 INSTALLATION GUIDE GlowShift.com © GlowShift Gauges, LLC | All Rights Reserved CHEVY / GMC DURAMAX 2 Pyrometer EGT Gauge Installation SECTION 2 Warning: Make sure the exhaust is cooled off during this process. 1. We are going to install the EGT probe in a preturbo location on the manifold to ensure the most accurate readings. Installing the EGT probe further downstream can display a lower temperature reading on the gauge. 2. Remove the front passenger wheel and the inner wheel well liner using a T-15 Torx Bit to remove the wheel well liner. 3. Using a 17mm wrench, remove the stock EGT sensor from the passenger side Exhaust Manifold. 4. Using a 10mm socket and wrench, remove the two rear heat shields on the Exhaust Manifold. 5. With the heat shields removed, locate an open area in front of the collector on the passenger side Exhaust Manifold. 6. Mark the manifold using a Center Punch to prepare the drilling and tapping process. 7. Starting with a 1/8” drill bit, drill your pilot hole into the manifold and gradually step up in drill bit size until you reach size R. Note: Clean the manifold with a pen magnet and shop vacuum to ensure no shavings are present in the manifold. 8. Take the 1/8-27 NPT Tap and slowly tap the size R hole in the manifold using cutting oil. Again, clean the manifold with a pen magnet and shop vacuum to remove all shavings. 2. 4. 7.
