Identifying the common issues in the R35 GT-R can help owners take proactive measures to prevent bigger problems down the line. Here are some of the most frequently reported weak points:
- Transmission issues
- Fuel pump failures
- Engine oil consumption
- Brake overheating
- Cooling system inefficiencies
Transmission Issues
The R35 GT-R is equipped with a dual-clutch transmission, which can sometimes experience issues, especially under aggressive driving conditions. Regular maintenance is crucial to ensure smooth operation.
Maintenance Tips for the Transmission
- Change transmission fluid regularly, ideally every 10,000 miles.
- Monitor for any unusual noises or shifting problems.
- Consider upgrading to a higher-performance transmission cooler if you track the vehicle.
Fuel Pump Failures
The fuel pump in the R35 GT-R can be susceptible to failure, particularly in modified cars or those that have been subject to rigorous driving. Keeping an eye on fuel delivery is essential.
Preventative Measures for the Fuel Pump
- Use high-quality fuel to minimize pump strain.
- Check fuel pressure regularly.
- Consider upgrading to a higher-capacity fuel pump if modifications are made.
Engine Oil Consumption
Some R35 GT-R owners report higher than normal engine oil consumption, which can lead to serious engine damage if not addressed. Regular checks and changes are essential.
Managing Engine Oil Levels
- Check oil levels frequently, especially before long drives.
- Use high-quality synthetic oil that meets Nissan specifications.
- Change oil every 5,000 miles or sooner if driven hard.
Brake Overheating
The R35 GT-R is built for speed, but that can lead to brake overheating during aggressive driving or track days. Addressing this issue is vital for safety and performance.
Improving Brake Performance
- Upgrade to performance brake pads and rotors.
- Consider installing a brake cooling system.
- Flush brake fluid regularly to maintain performance.
Cooling System Inefficiencies
Keeping the engine cool is critical, especially during high-performance driving. The R35 GT-R’s cooling system can struggle under extreme conditions, leading to overheating.
Enhancing the Cooling System
- Inspect and replace coolant regularly.
- Ensure the radiator is clean and free of debris.
- Consider upgrading the radiator or adding an auxiliary cooler for track use.
Conclusion
Maintaining the reliability of your R35 GT-R involves understanding its common weak points and taking proactive measures. By following these tips, you can enjoy the performance of your GT-R while minimizing the risk of issues. Regular maintenance and attention to detail will ensure that your vehicle remains in top condition for years to come.
