EXCERPT:
RAM 3500 HD Laramie - ENGINE Cooling System - Ram Pickup
OPERATION
The cooling system regulates engine operating temperature. It allows the engine to reach normal operating temperature as quickly as possible. It also maintains normal operating temperature and prevents overheating.
The cooling system also provides a source of hot coolant for heating the passenger compartment and cooling the automatic transmission fluid (if equipped). The cooling system is pressurized and uses a centrifugal water pump to circulate coolant throughout the system.
When engine is cold the thermostat is closed. The cooling system has no flow through the radiator. The coolant flows through the engine, water pump, and heater.
When engine is warm the thermostat is full open. One the gas engine coolant flows through the engine, radiator, heater, and water pump.
All engines utilize an ambient overflow bottle for coolant recovery/reserve.
An optional factory installed maximum duty cooling package is available on most models. This package will provide additional cooling capacity for vehicles used under extreme conditions such as trailer towing in high ambient temperatures.
DIAGNOSIS AND TESTING
PRELIMINARY CHECKS
ENGINE COOLING SYSTEM OVERHEATING
Establish what driving conditions caused the complaint. Abnormal loads on the cooling system such as the following may be the cause:
Prolonged idle
Very high ambient temperature
Overloaded Truck
Slow traffic
Traffic jams
High speed or steep grades
Snow Plow restricting airflow through cooling module
Debris on front of the grill or the cooling module that is restricting airflow
Driving techniques that avoid overheating are:
Idle with A/C off when temperature gauge is at end of normal range.
Increasing engine speed up to 2000 RPM with transmission in park or neutral for more airflow is recommended.
TRAILER TOWING:
Consult Trailer Towing section of the owner's manual. Do not exceed the limits.
RECENT SERVICE OR ACCIDENT REPAIR:
Determine if any recent service has been performed on vehicle that may affect the cooling system. This may be:
Engine adjustments (incorrect timing)
Slipping engine accessory drive belt(s)
Brakes (possibly dragging)
Changed parts. Incorrect water pump or pump rotating in wrong direction due to belt not correctly routed
Reconditioned radiator or cooling system refilling (possibly under filled or air trapped in system).
Service to electrically controlled viscous fan clutch
NOTE: If investigation reveals none of the previous items as a cause for an engine overheating complaint, refer to the COOLING SYSTEM DIAGNOSIS CHART.
These charts are to be used as a quick-reference only.
