LAS VEGAS, Nev. — To further simplify the working lives and improve the efficiency of truck operators in a variety of vocations, Mack has introduced a new routine maintenance monitoring system.

Known as GuardDog, the system alerts drivers, via an in-cab dashboard display, of the following service items:
* Engine Oil Level (low or high)
* Engine Coolant Level (low)
* Fuel Level (low)
* Windshield Washer Fluid Level (low)
* Air Filter Restriction (high)
* Steer Axle Brake Shoe (worn)
* Drive Axle(s) Brake Shoe (worn)

The GuardDog system also includes a Predictive Oil Change (POC) feature that automatically determines when an engine oil and filter change is due based on engine duty cycle.

The GuardDog system is currently available as an option on Vision by Mack, Granite and CH models equipped with Mack’s optional Vehicle Information Profiler (VIP) driver display.

GuardDog is an “active” maintenance monitoring system in that it is based on actual vehicle sensor readings, rather than predetermined or “passive” distance, time or date intervals.

“The main objective of many of today’s new product introductions is helping vehicle operators to concentrate on their main concern — driving the truck,” says Kevin Flaherty, senior vice-president of sales. “The GuardDog system also should favorably impact overall operating efficiency by reducing the time spent on routine maintenance, reducing pre-trip inspection time, and potentially extending brake shoe and engine oil life.”
