The first sign of failure is typically a wet spot on the outside of the cover, or a small drip on the ground under the axle. Left to corrode further, the axle loses fluid, or water gets into […]

See What’s Coming…

There’s a very cool new product arriving from Dorman. They’re offering active grille shutters that open and close automatically to control airflow through the radiator and into the engine compartment to regulate cooling. When cooling is not needed, the shutters close, routing the air around the vehicle to lessen aerodynamic drag and reduce fuel consumption. As a bonus, closed shutters also reduce vehicle cabin warm-up time during cold weather. FEATURES AND BENEFITS Direct-fit replacement for original equipment designs Plug-and-play installation comes with motor for a complete repair Quality testing includes vehicle try-on, material, and corrosion testing No programming required for final […]
