Supplier: Norman G. Clark

Price Guide: POA

It's compact and lightweight, too. Looking to upgrade your fleet's performance? Put the DriveMasterTM in your existing diesel engines for improved, optimum cooling performance and extended, maintenance-free operating life.

The superior design of the higher-torque, lighter-weight DriveMaster from Horton meets the demands of today’s high horsepower diesel engines.

It keeps engine coolant at a more consistent operating temperature and because it has less drag, it consumes less power in the off mode. That means better fuel economy and a much cooler bottom line for you.
