Filling - 6.7L Diesel

WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

ANTIFREEZE COOLANT IS HARMFUL IF SWALLOWED OR INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND INDUCE VOMITING. IF INHALED, MOVE TO FRESH AIR AREA. SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED CONTAINERS. WASH SKIN AND CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE GLYCOL. KEEP OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASED COOLANT PROPERLY. CONTACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION CENTER IN YOUR AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT OPERATING TEMPERATURE OR HOT UNDER PRESSURE; PERSONAL INJURY CAN RESULT. AVOID RADIATOR COOLING FAN AND OTHER MOVING COMPONENTS WHEN ENGINE COMPARTMENT RELATED SERVICE IS PERFORMED; PERSONAL INJURY CAN RESULT.

WARNING:

WEAR APPROPRIATE EYE AND HAND PROTECTION WHEN PERFORMING THIS PROCEDURE.

CAUTION:

Do not use well water or suspect water supply in cooling system. A 50/50 mixture of the recommended antifreeze coolant and distilled water is recommended.

NOTE:

Cooling system fill procedure is critical to overall cooling system performance.

NOTE:

Make sure all hoses are connected and radiator draincock is closed. Draincock should be hand tightened only.

CAUTION:

All air must be purged from the 6.7L engine when refilling the cooling system. Failure to do so can cause EGR Cooler cracking which can lead to catastrophic engine and exhaust system damage.

Close the radiator drain plug.
Using (special tool #8195A, Funnel), fill the cooling system with coolant mixture. Refer to COOLANT, DESCRIPTION .
Add coolant to the overflow bottle until the level reaches the top of the fill neck. Then, allow the coolant level in the overflow bottle to settle for 90 seconds. Check level again and add coolant if necessary for the level to reach the top of the filler neck.
Install overflow bottle cap. Start engine and idle for 2 minutes. Shut off engine and ensure the coolant level is at the top of the overflow bottle filler neck. If coolant is added re-install the cap.
Start the engine and with the transmission in park and/or neutral, operate the engine at 2000 RPM. Monitor the coolant temperature on the EVIC. Once the temperature has reached 200° F, continue to operate the engine at 2000 RPM for 10 minutes, then shut the engine off.
After the engine has cooled check the coolant level. If coolant level is below the 'full Cold' marker, add coolant.
