This guide provides a comprehensive walkthrough for installing a 2014 Chevy Cruze 2.0 Diesel Delete Kit. This is not a beginner-level project and requires mechanical experience. This guide should be used as a reference and not a strict instruction manual. Always prioritize safety and use common sense.
Tools Required for 2014 Chevy Cruze Diesel Delete
Before you begin, gather the following tools:
- Sockets: 7mm, 10mm, 13mm, 15mm, 16mm (regular and deep)
- 3/8″ Ratchet and small extensions
- Open-end wrenches: 10mm, 13mm, 15mm
- Crescent wrenches (various sizes for sensors)
- Air ratchet (optional, but recommended)
- Needle-nose pliers
- Vise grips
- Small flathead screwdriver
- Ball peen hammer
- Small pry bar
- PB Blaster penetrating oil
- Hex head socket set or long hex head wrench
- Small pick for electrical connector locks
DPF Removal on a 2014 Chevy Cruze
-
Prepare the Vehicle: Park on level ground, engage the parking brake, and chock the rear wheels. Disconnect the battery.
-
Engine Bay Access: Remove the engine cover and the upper heat shield (four 10mm bolts).
-
Sensor Disconnection: Loosen the DPF/Turbo clamp (16mm deep socket) and apply PB Blaster. Disconnect the NOX #1 sensor, EGT #1 sensor, and EGT #2 sensor. Disconnect the O2 #1 sensor at the plug near the radiator support.
-
Lower Heat Shield Removal: Remove accessible 10mm bolts from the lower heat shield. Jack up the front of the vehicle and secure it with jack stands. Remove the remaining lower heat shield bolts from underneath, threading the O2 sensor wiring carefully. Remove the lower engine splash guard (7mm bolts and push pins).
-
DPF Detachment: Remove the exhaust flange bolts (13mm), the two DPF-to-oil pan bolts, and the DPF bracket bolts (15mm deep socket). Separate the DPF from the turbo using a pry bar and screwdriver, preserving the metal gasket.
-
Final Steps: Disconnect the two vacuum lines on the DPF. Remove the DPF, avoiding contact with A/C lines. Remove the O2 sensor from the DPF and clean all sensors.
Downpipe Installation
-
Sensor Installation: Thread the O2 sensor into the designated bung on the new downpipe.
-
Downpipe Placement: Position the downpipe, reinstall the exhaust gasket, and secure the turbo/downpipe clamp. Hand-tighten the exhaust flange bolts.
-
Sensor Reinstallation: Reinstall the NOX #1, EGT #1, and EGT #2 sensors.
-
Finalization: Ensure proper alignment and tighten all connections. Reinstall the lower engine splash guard. Lower the vehicle. Note: The removed vacuum lines are not reused.
EGR System Removal and Delete
-
EGR Tube Removal: Locate the EGR tube and remove the two 10mm bolts from the intake plate. Disconnect the EGR sensor wire. Remove the two hex head bolts securing the tube to the EGR actuator valve. Disconnect the brownish-orange connection to the actuator. Remove the EGR tube and gaskets.
-
EGR Delete Plate Installation: Install the lower plate with gasket and bolts. Install the intake-side plate with gasket and bolts. Install three NPT plugs into the intake-side plate using thread sealant.
ECM Recalibration
- Disconnect the throttle valve connection. Reconnect the battery.
- Follow the instructions provided with your OZ Tuning software for ECM recalibration.
Conclusion
Successfully installing a 2014 Chevy Cruze 2.0 diesel delete kit requires careful attention to detail and mechanical proficiency. Remember that three electrical connections (EGR sensor, EGR actuator, and throttle valve) remain unplugged after the installation and ECM flash. Always double-check your work and consult a professional if needed.
