Removing the Stock Intercooler
Removing the stock intercooler is the first major step in the installation process. Follow these guidelines:
- Disconnect Battery: Always disconnect the negative battery terminal to prevent electrical issues.
- Remove Air Intake: Take off the air intake system to access the intercooler more easily.
- Unbolt the Stock Intercooler: Carefully unbolt the stock intercooler from its mounting points and remove it from the vehicle.
Installing the Snow Performance Intercooler
With the stock intercooler removed, it’s time to install the Snow Performance air to water intercooler. Here’s how:
- Position the Intercooler: Place the intercooler in the designated area, ensuring it fits snugly without obstruction.
- Secure the Intercooler: Use the provided bolts and brackets to secure the intercooler in place.
- Connect Hoses: Attach the water lines and ensure they are tightly secured to prevent leaks.
Wiring the System
Proper wiring is essential for the functionality of the intercooler. Follow these steps:
- Connect the Pump: Wire the intercooler pump according to the instructions, ensuring proper power supply.
- Install the Switch: If applicable, install a switch to manually control the pump.
- Test Connections: Double-check all electrical connections for security and proper insulation.
Filling the System
Once the intercooler is installed and wired, it’s time to fill the system with the appropriate fluid:
- Choose the Right Fluid: Use a water-methanol mix as recommended by Snow Performance for optimal performance.
- Fill the Reservoir: Pour the mixture into the intercooler reservoir until it reaches the recommended level.
- Check for Leaks: Before starting the vehicle, inspect all connections for any signs of leaks.
Testing the Installation
After installation, it’s crucial to test the system to ensure everything is functioning properly:
- Reconnect the Battery: Reconnect the negative battery terminal and ensure all electrical components are functioning.
- Start the Engine: Start the vehicle and listen for any unusual noises that may indicate installation issues.
- Monitor Temperatures: Use an OBD-II scanner or gauge to monitor intake temperatures during a test drive.
Maintenance Tips
To keep your Snow Performance intercooler functioning at its best, follow these maintenance tips:
- Regular Fluid Checks: Periodically check the fluid level in the reservoir and replenish as needed.
- Inspect Hoses: Regularly inspect hoses for wear or damage and replace them if necessary.
- Clean the System: Follow manufacturer guidelines for cleaning the intercooler and associated components.
Conclusion
Installing a Snow Performance air to water intercooler on a Subaru WRX can dramatically enhance performance when done correctly. By following these best practices, you can ensure a successful installation and enjoy the benefits of improved engine efficiency.
