Cooling & Radiators

One area where the truck manufacturers cut corners is on the cooling system. They only give the standard trucks enough cooling for a 3% grade in the summer months. A Peterbilt 379 with a 500 HP Detroit 12.7 will have 177 coolant tubes in the radiator. The same truck with a 550 HP CAT will have 234 coolant tubes. The Pittsburgh Power radiator has 400 tubes, about twice as many depending on the application. It also has 16 fins per square inch verses 14 fins on the stock radiator.  Our radiator has dimpled tubes unlike the straight tubes in the standard radiators. Dimpled tubes are much more effective at cooling because of the increased surface area touching the coolant. Don't forget to install our 180 degree thermostat as well. 


Please call to order one of our radiators or charge air coolers. (724) 360 4080.
