Radiator cooling plate is a device to direct air to flow efficiently from grille to the radiator for better cooling that is installed between front grille and the radiator top. Air escapes from the top of radiator instead of going through radiator on most stock vehicles. Radiator cooling plate restricts escaping air by connecting top of the grille to the radiator. This result more air to flow through radiator for more efficient cooling that prevent overheating. This Radiator cooling plate also works as good under the hood dress up item.
Some of the air entering from front grill does not go through radiator but rather escapes from the space around and between the radiator and front grill. Re-directing air flow by plugging the space between them will greatly increases radiator efficiency. Thus cools radiator and prevent over heating.
