The TRD supercharger, an intercooled roots-type Eaton M90, breathes new life into the Toyota FJ Cruiser. While considered a sealed unit with a 100,000-mile maintenance-free lifespan, proactive maintenance can significantly extend its life and ensure optimal performance. This guide delves into essential maintenance procedures for your Trd Supercharged Fj Cruiser.
Essential TRD Supercharger Maintenance Procedures
Regular upkeep is key to maximizing the lifespan and performance of your supercharger. Here’s a breakdown of essential maintenance tasks:
1. Belt Inspection and Replacement
Frequent inspection and timely replacement of the supercharger belt are crucial. Aim for replacement every 10,000 miles to prevent slippage and boost loss. Recommended replacement belts include:
- TRD PTR30-35070
- Dayco 5PK1790
- Goodyear Poly-V Gatorback 4050705 5PK1790
A serpentine belt tool kit simplifies the replacement process.
2. Coolant System Checks
Regularly check the coolant reservoir fluid levels. Ensure the level is within the designated range without overfilling. Use Toyota Super Long Life Coolant #00272-SLLC2 (the pink coolant). Also, verify the functionality of the coolant reservoir pump. Consider replacing it with a more robust Johnson CM30P7-1 or a Ford Racing LIGHTNING Intercooler Pump. Address any leaks promptly.
3. Nose Oil Change
Changing the nose oil every 30,000 miles prevents metal shavings from the nose bearings from contaminating the main impeller bearings, thus prolonging the supercharger’s life. Use 6 ounces of GM supercharger oil (two 4oz tubes).
4. Coupler Replacement
The coupler bearing is a common wear item. Replace it if you hear a rattling sound at idle, indicating worn coupler holes. Consider Eaton Nose Cone Service Kits or aftermarket options from reputable suppliers.
5. Nose Rebuild/Replacement
A significantly louder rattling sound indicates the need for a nose drive overhaul or replacement. Consult resources like Rolling Performance for guidance on rebuilding the Eaton snout.
6. Intercooler Cleaning
Clean the intercooler core during the 30,000-mile nose oil change to remove oil accumulation and improve cooling efficiency. Installing an oil catch can minimizes blow-by collection on the intercooler.
7. Supercharger Rebuilds
For major issues, consider a professional supercharger rebuild from reputable companies like PSE Superchargers, Stiegemeier, Magnuson Products, or Jon Bond Performance.
8. Spark Plug Maintenance
The specialized spark plugs in the TRD supercharged FJ Cruiser are designed for 100,000 miles. While accessible without supercharger removal, changing them during other maintenance procedures is more convenient.
Conclusion
Maintaining your TRD supercharged FJ Cruiser involves more than just routine oil changes. By adhering to this comprehensive maintenance guide, you can ensure your supercharger performs optimally for years to come, delivering the exhilarating driving experience you expect. Remember to consult reputable resources and professionals for specific procedures and guidance.
