2010-2018 INSTALLATION GUIDE 1 GlowShift.com © GlowShift Gauges, LLC | All Rights Reserved RAM 6.7L CUMMINS PREPARING THE INSTALLATION • Check that you have all parts required for installation, and that the engine is cool. • Open the hood and locate the truck’s batteries. Using a wrench, disconnect the negative terminal of each battery to ensure there is no power running through the truck during the installation. Note: When it comes time to wire and connect the gauges to their power source, you will be able to reconnect the negative terminals on the batteries. Note: If you are installing a MaxTow Boost Gauge, you will be installing an electronic Boost Pressure Sensor and Harness instead of the Boost Line and Ferrule Fittings. The Boost Gauge can be installed by using a Boost Bolt Adapter that threads directly to the intake manifold horn and replaces the front inner intake heater grid bolt: 1. Remove the engine cover using an 8mm Socket. 2. Locate and remove the front inner intake heater grid bolt using a 10mm Socket with extension. 3. Attach the compression adapter to the Boost Bolt using a 17mm Wrench and 11mm Wrench. Note: Use Teflon Tape on the 1/8-27NPT threads. 4. Install the Boost Bolt assembly using a 17mm Wrench and torque to 10 foot-pounds using a Torque Wrench. 5. Insert the boost line fitting cap on the boost line followed by the ferrule. 6. Insert the boost line into the boost line fitting and tighten the cap with a 3/8” wrench. (Refer to diagram below) Note: Do not overtighten. 7. Route the boost hose up to the firewall to the driver side of the engine bay and use Zip Ties to secure the hose. Ensure there is no contact with any direct heat source or moving parts of the truck. 8. Reinstall the engine covering using an 8mm Socket. 3. 6. PROPER ORIENTATION Boost Gauge Installation SECTION 1
2010-2018 INSTALLATION GUIDE GlowShift.com © GlowShift Gauges, LLC | All Rights Reserved RAM 6.7L CUMMINS 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 pre-turbo 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. To install the EGT probe, we are going to use GlowShift’s Drill and Tap Kit. Optional: Safely jack up the truck for easier access to the driver’s side exhaust manifold. 2. Locate the exhaust manifold on the passenger side of the engine bay, where the collector is also positioned. Using a center punch, mark the location where you are going to drill a hole for the EGT probe on the manifold on the left side of the collector to prepare the drilling and tapping process. Note: There is a divider in the middle, so you will need to drill on either side of the divider to ensure the hole is unobstructed. 3. Starting with a 1/8” drill bit, drill a pilot hole into the exhaust manifold. Continue increasing the size of the pilot hole using various drill bits until you reach size R. 4. Using cutting oil, tap the hole to 1/8-27 NPT. 5. Ensure all shavings are out of the manifold by periodically using a vacuum and a pen magnet to remove them. Warning: Failure to remove metal shavings can result in possible engine damage. 6. Apply anti-seize to the threads of the EGT ferrule fitting and thread the fitting into the exhaust manifold. Tighten the fitting with a 14mm wrench. 7. Install the gauge’s EGT Probe into the Ferrule Fitting Adapter, ensuring the sensor is positioned approximately halfway into the manifold. Tighten using a 14mm wrench. Note: Do not overtighten the ferrule fitting. 8. Plug the EGT Sensor Harness into the EGT Sensor. 9. Route the EGT Sensor Harness to an opening on the firewall on the driver’s side of the engine bay and use Zip Ties to secure. Make sure there is no contact with any direct heat source or moving parts. Optional: Lower the vehicle if it was raised. 3. 4. 7.
2010-2018 INSTALLATION GUIDE 3 GlowShift.com © GlowShift Gauges, LLC | All Rights Reserved RAM 6.7L CUMMINS Transmission Temp Gauge Installation SECTION 3 We install the Transmission Temperature Gauge using a 1/2” Transmission Line T-Fitting Adapter: Warning : Be sure that the transmission is cool before removing the transmission cooler line. 1. Safely jack up the truck, if not raised already. Have a Drain Pan available for any fluid that will leak. 2. Using a 20mm and 24mm Wrench, loosen the transmission hot side cooler line. Note: The line is on the passenger side of the transmission. 3. Using a Pick Tool, remove the retaining clip and then remove the trans cooler line which leads to the “hot side.” 4. While the fluid is draining out of the line, hold up the T-Fitting Adapter to check for clearance. 5. Using a Marker, mark the cooler line where you will cut to remove approximately 1-7/8” of the line. Use the Pipe Cutter to cut the line where you have made your marks and then deburr the cut ends. Insert the nut and cutting ring onto the line where you have just made your cut and repeat on the other side. Note: Be sure to clean out any loose material from the line. 6. Install the cooler line T-fitting female compression nuts over each end of the cut line. Then place the metal cutting rings over each end of the cooler line. 7. Now you can install the 1/8-27 NPT temperature sensor into the port on the T-fitting housing. Note: Be sure to use Teflon Tape on the threads of the temperature sensor to prevent any leaks. 8. Hold the body of the T-fitting with a Wrench and hand tighten each compression nut. Then tighten 1-1/4 more turns with a 7/8” and a 22mm Wrench to ensure proper sealing of the cutting rings. 9. Reinstall the line fitting with the T-Fitting Adapter attached and refill the transmission with up to 4 quarts of proper grade Transmission Fluid. Note: Check the dipstick to ensure the proper amount of fluid is in the transmission. Wiring the Transmission Temperature Gauge: 1. Connect the signal wire of the gauge to the white wire of the temperature sensor and connect the black wire of the sensor to any reliable grounding location. 2. Route the wires up to the firewall to the driver side of the engine bay and use Zip Ties to secure the sensor wires. Ensure there is no contact with any direct heat source or moving parts. 3. 6A. 6B.
