Cleaning and Maintenance Tips
If the intercooler appears dirty or clogged, clean it carefully. Use compressed air or a soft brush to remove debris from the fins. Avoid bending or damaging the fins during cleaning.
Replace any damaged hoses or clamps. Ensure all connections are tight and secure before reassembling. Reinstall the intercooler and covers, reconnect the battery, and start the engine to check for proper operation.
