The GT-R is a legendary vehicle known for its performance and tuning potential. One of the key upgrades enthusiasts often pursue is the intercooler, which plays a vital role in cooling the intake air. In this guide, we will walk you through the process of replacing the HKS 3.5-inch core intercooler with a new unit, ensuring your GT-R continues to perform at its best.
Tools and Materials Needed
- Socket set
- Wrench set
- Flathead screwdriver
- Phillips screwdriver
- Intercooler replacement unit
- New silicone hoses
- Clamps
- Torque wrench
- Heat-resistant gloves
Preparation Steps
Before starting the installation, ensure you have a clean workspace and all the necessary tools and materials at hand. It’s also advisable to allow the engine to cool down completely to avoid burns while working on the intercooler.
Step 1: Remove the Front Bumper
The first step in replacing the intercooler is to remove the front bumper to access the intercooler. Begin by unscrewing the screws and bolts holding the bumper in place. Typically, these can be found:
- Underneath the front lip
- Inside the wheel wells
- At the top near the hood
Once all screws and bolts are removed, gently pull the bumper away from the vehicle and set it aside in a safe location.
Step 2: Disconnect the Old Intercooler
With the bumper removed, you can now access the intercooler. Start by disconnecting the piping connected to the old HKS intercooler. Use a flathead screwdriver to loosen the clamps and carefully pull the hoses off the intercooler.
Next, remove any mounting bolts securing the intercooler to the vehicle. Make sure to keep these bolts as you will need them for the new intercooler installation.
Step 3: Install the New Intercooler
Take your new intercooler and position it where the old intercooler was mounted. Align it with the mounting holes, and secure it using the bolts you previously removed. Tighten the bolts to the manufacturer’s specified torque settings.
Once the intercooler is secured, reconnect the piping. Make sure to use new silicone hoses if necessary, and tighten the clamps securely to prevent any leaks.
Step 4: Reattach the Front Bumper
With the new intercooler installed and all connections secured, it’s time to reattach the front bumper. Carefully align the bumper with the mounting points and push it back into place. Reinsert all screws and bolts that were removed earlier, ensuring a snug fit.
Step 5: Final Checks
After reattaching the bumper, it’s essential to do a thorough check of all connections and fittings. Ensure that:
- All clamps are tight
- There are no visible leaks
- All bolts are secured
Once you have confirmed everything is in order, start the engine and let it idle for a few minutes. Check for any irregular sounds or leaks. If everything appears normal, you’re ready to hit the road!
Conclusion
Replacing the HKS 3.5-inch intercooler in your GT-R can significantly improve performance and efficiency. By following this step-by-step guide, you can ensure a successful installation. Always remember to perform regular maintenance checks to keep your intercooler and overall system functioning optimally.
