Problem overview

Some Ram 2500 owners report experiencing high oil temperatures while towing a light trailer, despite multiple repairs. These issues can be exacerbated under normal operating conditions, particularly when climbing steep inclines or carrying heavy loads. Owners are advised to ensure their cooling system is functioning optimally, checking the radiator, coolant levels, and cooling fan operation to prevent overheating. Additionally, some consider adding an aftermarket oil cooler to regulate oil temperatures during towing, especially for frequent heavy loads. Upgrading the thermostat may also help delay temperature spikes, although the vehicle's computer system plays a role in temperature regulation. Furthermore, using synthetic oil is recommended as it can withstand higher temperatures without breaking down, offering better engine protection. Monitoring both engine coolant and oil temperatures while towing is crucial, as oil temperatures may temporarily exceed coolant temperatures under heavy load but should normalize once the load is reduced.
