Cooling System
Cooling system parts are not optional on a diesel that tows, runs hot, or has higher mileage. Plugged oil coolers, weak water pumps, tired fan clutches, and leaking hoses can turn into head gasket work if ignored too long.
Radiators, water pumps, thermostats, coolant filtration systems, bypass kits, cooling fans, hoses, and oil cooler components for Cummins, Duramax, and Power Stroke applications are all part of this section. A lot of trucks end up needing cooling upgrades after towing heavier or adding power.
