Step-by-Step Installation
Step 1: Preparation
Disconnect Batteries
Remove the negative terminals from both batteries to ensure safety.
Remove Air Intake Pipe
Unbolt and set aside the air intake pipe to clear access to the EGR cooler.
Drain Coolant
Remove the inner fender liner to access the radiator hose.
Disconnect the hose and allow a few liters of coolant to drain into a pan.
Verification: Ensure all coolant flow has stopped before proceeding.
Step 2: Remove the EGR Cooler
Disconnect Wiring
Unplug the coolant level sensor, A/C wiring, and other electrical connections.
Move the harness aside for better access.
Detach PCV Piping
Loosen the 10mm bolts and V-band clamp securing the PCV piping.
Disconnect the pipe from the intake horn and turbo.
Cut Coolant Hoses
Use an Exacto knife to cut the hoses connected to the EGR cooler, as they will be replaced.
Unbolt the EGR Cooler
Remove all bolts securing the cooler.
Pry it loose where it connects to the up pipe.
Lift Out the Cooler
Carefully remove the EGR cooler, noting carbon buildup at the ports.
Verification: Ensure the cooler and all hoses are fully removed before proceeding.
Step 3: Modify or Replace the Up Pipe
Remove Up Pipe
Unbolt the up pipe from the turbo (3 bolts) and exhaust manifold (3 bolts).
Use a torch to loosen stubborn bolts.
Modify the Pipe
Cut off the EGR branch using a grinder.
Weld a solid cap over the opening and apply anti-corrosion paint.
Reinstall the Up Pipe
Use anti-seize on all bolts and secure the modified pipe to the turbo and exhaust manifold.
SPETUNER Alternative: Install a pre-fabricated SPETUNER up pipe without an EGR port to save time and avoid welding.
Verification: Check for tight, secure connections without leaks.
Step 4: Replace the Downpipe
Remove Factory Downpipe
Remove the turbo heat shield and loosen the V-band clamp.
Slide out the downpipe, maneuvering it through the frame.
Install New Downpipe
Position the SPETUNER downpipe for better airflow and tighten all connections.
Verification: Confirm that all bolts are secure, and there are no gaps or leaks in the exhaust system.
Step 5: Install Blocker Plates
Clean Intake Horn Ports
Use a wire brush and carburetor cleaner to remove carbon buildup from the ports.
Attach Blocker Plates
Secure the SPETUNER blocker plates to the intake horn using provided brackets and spacers.
Tighten bolts to ensure a flush fit.
Verification: Ensure blocker plates are properly sealed to prevent leaks.
Step 6: Install the New Coolant Line
-
Route the Line
Connect the new coolant line from the firewall to the radiator.
Secure it with clamps to prevent leaks.
SPETUNER Advantage: Pre-measured coolant lines eliminate guesswork for a precise fit.
Verification: Double-check the connection points and test for leaks after adding coolant.
Step 7: Final Assembly
Reinstall Components
Turbo intake horn and PCV piping.
Air intake system.
Electrical wiring and sensors.
Refill Coolant
Fill the system and bleed air by loosening the thermostat housing screw until coolant flows out.
Verification: Check all connections, bolts, and fluid levels before starting the engine.
After Installation
-
Test Drive
Ensure the truck runs smoothly with no leaks or error codes. -
Monitor Levels
Check oil and coolant levels for a few days after installation. -
Follow-Up Maintenance
Inspect bolts and seals periodically to ensure long-term reliability.
