Griffin Radiator for a 1970 GTO - Fits 14 inch fans - FMG

Keep your 28.3" x 17.27" core Griffin Radiator running cool with this precision-engineered fan shroud

Upgrade your cooling system with our custom-designed shroud for the 28 x 17 Griffin radiator that delivers measurably better cooling efficiency than the standard Cold Case shroud design. Through optimized fan sizing and precision-engineered airflow channels, this shroud maximizes the contact between your fan and radiator surface—ensuring every CFM of airflow does its job.

Key Performance Advantages:

• Enhanced Shroud performance: Flap doors allow "pass through" of high velocity air while at speed, dramatically cutting down the need for fan usage.
• Optimized Fan Size: Direct fit 14" fans were selected by Monty
• Not sure which fans to use? Check out Monty's independent fan CFM test results to see real-world performance data and compare different fan options.
• Better Fitment: Custom-contoured to the Cold Case Radiator for a truly integrated cooling solution, overlapping the side tanks, accommodating larger fans.
