Summary

Engine Overheat When Driving Aggressively with Accessory Grille and Outboard Cooler Installed Condition - Some customers may comment on the vehicle overheating when driving aggressively with accessory grille installed in addition to outboard cooler installed. Cause - This may be due to outboard aero blockers restricting airflow to the outboard coolers, causing the vehicle to overheat. Correction - If the vehicle is equipped with (RPO V18) outboard coolers and an accessory grille, the grille blockers should not be installed. If installed, they should be removed.
