Keep your Pontiac running cool with this precision-engineered fan shroud
Upgrade your cooling system with our custom-designed shroud for the Cold Case GPG38 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
- 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 three piece cooling solution, overlapping the side brackets, accommodating larger fans.

- Spal 30102042 (14" Brushed High Performance Puller)

You don't get many products these days that are superb. Hopefully sufficient is the usual. The products from Fast Monty's Garage are hand engineered by Mike...with I'm guessing some CAD system. They are hand fit, tested, modified and finally produced. And, the products are reasonably priced. It doesn't get any better than exceedingly good. Excellent!
