Big Cam Cooling System Conversion: A Game-Changer for Vintage Trucks

When it comes to vintage trucks, few names evoke as much nostalgia and respect as Cummins' Big Cam engine. With its powerful performance and rugged durability, it's no wonder that many owner operators still rely on these engines today. But for those who've owned a Big Cam-equipped truck in the past, one common issue has often plagued them: the low-flow cooling system.

Introduced through 1985, Cummins' high-flow cooling system revolutionized engine performance by allowing for more efficient heat dissipation and reduced risk of overheating. However, many early Big Cam engines were equipped with the lower-flow system, which could lead to issues in hot weather or demanding driving conditions.

Fortunately, Pittsburgh Power offers a complete conversion kit designed specifically for owners looking to upgrade their low-flow cooling systems to full flow. According to Peter Sharp, Vice President of Pittsburgh Power and a 30-year veteran of working with Big Cam engines, the benefits of this conversion are undeniable.

'We've never experienced high water temperature issues as long as the radiator, water pump, and radiator cap were functioning properly,' says Sharp. 'The high-flow system used through 1985 worked superbly, and we can ensure that you have all the parts needed to make the conversion.'

The process of upgrading your cooling system is relatively straightforward, depending on your engine configuration. For those with a Big Cam IV or 88 NT, new front water manifold sections and thermostat housing may be required. However, owners of earlier Big Cam IC engines can use used parts from later models, combined with a new radiator and water pump.

The payoff for this conversion is well worth the effort. Not only will your engine perform better and run cooler in demanding situations, but it'll also provide peace of mind knowing that you've addressed one of the most common issues associated with vintage trucks.

As 10-4 Magazine celebrates its 25-year anniversary, Pittsburgh Power is proud to have been a part of this journey, working closely with the magazine's team over the years. Here's to many more years of providing top-notch diesel engine performance and solutions for owner operators everywhere!
