EGR Delete Kit Installation Guide

The Exhaust Gas Recirculation (EGR) Delete Kit is a valve-based system responsible for reducing pollutants on your diesel-based vehicle's exhaust. It's all part of the government's efforts to reduce carbon emissions from vehicles.

This system or delete kit was implemented and required for vehicles to have back in 2007. It specifically reduces nitrogen oxide omissions that make air pollution worse across the board and all over the world. Once it's damaged, here's what you can do in order to install a new kit.

Installing an EGR Delete Kit

  • What You'll Need: You will need a new EGR delete kit, wrench metric socket set, slot screwdriver or pliers, Torx head screwdriver, and solvent spray. As for installation, you need to park your car in neutral first with the emergency brake turned on. Afterwards, pop your hood and take off the negative battery terminal. Before installation, make sure the engine has cooled down to protect yourself from injury.
  • Finding the Old EGR: Your engine should also be cool because the EGR' valve sustains heat and can burn your bare hands from its hotness. The driver's side exhaust manifold has metal tubing wherein the exhaust gas is sent to the valve of your EGR. Trace where the tube goes to find the mounting location of the EGR unit. This is the easiest way to find the unit. Where the EGR is placed depends on how big your engine is.
  • Remove the Tube and Wiring Harness: The valve of the EGR is on the intake manifold and looks like a small diaphragm with vacuum hose links all over its body. Loosen up the nut that secures the tube to the valve with an adjustable wrench. Afterwards, pull the tube off the valve and take off the wiring harness connected to the opposite side of the EGR valve.
  • Hose and Clamp Removal: Vacuum Hoses and Pull the vacuum hoses atop the EGR unit loose or loosen the clamp holding them in place. Mark the order of removal then wedge them aside. Remove the clamp that holds the hot air supply hose on the bottom of the EGR unit. It's a clamp that can either be spring-type or hose-type. Use pliers for the spring. Use a slot screwdriver for the hose. Twist the host from side to side while tugging it downward without forcing the pull.
  • EGR Removal and Replacement: Use the Torx screwdriver to remove the bolts connecting the EGR valve to the engine. Spray solvent spray on the mounting bolts and let it soak if they're rusted shut. Use the correct metric socket or hand wrench to remove the bolts of the EGR unit itself. Pull the EGR unit out, put in the new EGR, and go in reverse order in putting back everything together, from clamp to hose to metal tubing to everything else.
