Keep your Pontiac running cool with this precision-engineered fan shroud
Upgrade your cooling system with our custom-designed shroud for the Cold Case GMG34 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.
While the standard Cold Case shroud is a solid choice, our design takes cooling performance to the next level—ideal for high-performance builds, hot climates, or anyone who demands the absolute best from their cooling system.
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
Better Fitment: Custom-contoured to the Cold Case Radiator for a truly integrated three piece cooling solution, overlapping the side brackets, accommodating larger fans.
