K-9 Vehicle Overheating

Border Patrol Hood Louvers

Size Large RunCool Hood Louvers on U.S. Border Patrol pickup. This is an early installation (Standard Flow). We developed the Hi-Flow version for them — 50% more louvers per panel for 50% more flow — needed when it is 150° in the desert! Note roll bar and extended stand for scanning the desert.



Interesting Story —

A man recently called from New Mexico and asked about our Hood Louvers. His F250 was overheating, towing in hot weather. He said, “I saw a U.S. Border Patrol vehicle with hood louvers and asked the Border Patrol Agent, “Where did you get those hood louvers?” He said, “Call RunCool Hood Louvers”. And, I did! And, I’m glad I did!

Increase vehicle reliability and performance and improve the service life of underhood components with RunCool patented Hood Louvers. Various types of U.S. Border Patrol vehicles use these in the desert, where the temperatures can reach 150°! They want their Agents to be able to run the A/C (especially with K-9 vehicles) when temperatures reach those high levels.

Four Directions Search, Rescue and Recovery in Colorado says,

“It is unbelievable how well they work. I would never believe the difference they could make.” In fact, testing by the Pelion, S.C. Police Department showed our hood louvers lowered under-hood temperatures by 47°.
