Tools and Materials Needed
- APR 3.5-inch intercooler kit
- Socket set
- Torque wrench
- Flathead screwdriver
- Phillips screwdriver
- Ratchet
- Coolant (if necessary)
- Shop towels
- Safety glasses
Preparation Steps
Before starting the installation, ensure your vehicle is parked on a flat surface, and the engine is cool. Gather all the tools and materials listed above to streamline the process.
Step 1: Remove the Front Bumper
To access the intercooler, you need to remove the front bumper. Start by unscrewing the screws and bolts that secure the bumper to the vehicle. Typically, these are located:
- Underneath the front of the car
- Along the wheel wells
- At the top of the grille
Once all screws and bolts are removed, gently pull the bumper away from the car. Be cautious of any clips that may still be attached.
Step 2: Disconnect the Existing Intercooler
With the bumper removed, locate the existing intercooler. Disconnect the hoses and any electrical connectors attached to it. Make sure to have shop towels handy to catch any coolant that may spill during disconnection.
Step 3: Remove the Old Intercooler
Using your socket set, remove the bolts securing the old intercooler to the vehicle. Carefully lift the intercooler out of its place. Check for any debris or damage in the area before proceeding.
