An authorized dealer has the qualified service personnel, special tools, and equipment to perform all service opera- tions in an expert manner. Service Manuals are available which include detailed service information for your vehicle. Refer to these Service Manuals before attempting any proce- dure yourself.
NOTE:
Intentional tampering with emissions control systems may void your warranty and could result in civil penalties being assessed against you.
The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. Refer to the “Maintenance Plan” for further information.
For best performance and maximum protection under all types of operating conditions, the manufacturer only recom- mends engine oils that are API Certified and meet the requirements of FCA Material Standard MS-12633.
This symbol means that the oil has been certified by the American Petroleum Institute (API). The manu- facturer only recommends API Certified engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30, 5W-30 and 10W-30 engine oils.
NOTE: 7
Under no circumstances should oil change intervals exceed 8,000 miles (13,000 km), twelve months or 350 hours of engine run time, whichever comes first. The 350 hours of engine run or idle time is generally only a concern for fleet customers.
Use Mopar SAE 0W-40 engine oil approved to FCA Material Standard MS-12633 such as Pennzoil Ultra equivalent is recommended for all operating temperatures.
The engine oil filler cap also shows the recommended engine oil viscosity for your engine. For information on engine oil filler cap location, refer to the “Engine Compartment” illus- tration in this section.
Lubricants which do not have both the engine oil certifica- tion mark and the correct SAE viscosity grade number should not be used.
You may use synthetic engine oils provided the recom- mended oil quality requirements are met, and the recom- mended maintenance intervals for oil and filter changes are followed.
Synthetic engine oils which do not have both the engine oil certification mark and the correct SAE viscosity grade number should not be used.
The manufacturer strongly recommends against the addi- tion of any additives (other than leak detection dyes) to the engine oil. Engine oil is an engineered product and its perfor- mance may be impaired by supplemental additives.
Care should be taken in disposing of used engine oil and oil filters from your vehicle. Used oil and oil filters, indiscrimi- nately discarded, can present a problem to the environment. Contact an authorized dealer, service station or govern- mental agency for advice on how and where used oil and oil filters can be safely discarded in your area.
The engine oil filter should be replaced with a new filter at every engine oil change.
Engine Oil Filter Selection
This manufacturer's engines have a full-flow type disposable oil filter. Use a filter of this type for replacement. The quality of replacement filters varies considerably. Only high quality filters should be used to assure most efficient service. Mopar engine oil filters are high quality oil filters and are recom- mended.

The best protection against carbon monoxide entry into the vehicle body is a properly maintained engine exhaust system.
If you notice a change in the sound of the exhaust system; or if the exhaust fumes can be detected inside the vehicle; or when the underside or rear of the vehicle is damaged; have an authorized technician inspect the complete exhaust system and adjacent body areas for broken, damaged, dete- riorated, or mispositioned parts. Open seams or loose connections could permit exhaust fumes to seep into the passenger compartment. In addition, have the exhaust system inspected each time the vehicle is raised for lubrica- tion or oil change. Replace as required.
Under normal operating conditions, the catalytic converter will not require maintenance. However, it is important to keep the engine properly tuned to assure proper catalyst operation and prevent possible catalyst damage.
NOTE: 7
(Continued)
Intentional tampering with emissions control systems can result in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning engine operation, a scorching odor may suggest severe and abnormal catalyst overheating. If this occurs, stop the vehicle, turn off the engine and allow it to cool. Service, including a tune-up to manufacturer's specifications, should be obtained immediately.
To minimize the possibility of catalytic converter damage:
(Continued)
Check the engine coolant (antifreeze) protection every 12 months (before the onset of freezing weather, where applicable). If the engine coolant (antifreeze) is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh coolant. Check the front of the A/C condenser (if equipped) or radiator for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the A/C condenser (if equipped) or the back of the radiator core.
Check the engine cooling system hoses for brittle rubber, cracking, tears, cuts and tightness of the connection at the coolant recovery bottle and radiator. Inspect the entire system for leaks.
DO NOT REMOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.
NOTE:
Some vehicles require special tools to add coolant properly. Failure to fill these systems properly could lead to severe internal engine damage. If any coolant is needed to be added to the system please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or contains visible sediment, have an authorized dealer clean and flush with OAT coolant (antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in this section for the proper maintenance intervals.
(antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into the cooling system in an emergency, the cooling system will need to be drained, flushed, and refilled with fresh OAT coolant (conforming to MS.90032), by an authorized dealer as soon as possible.
Refer to “Fluids And Lubricants” in “Technical Specifica-
erly. Failure to fill these systems properly could lead to 7
tions” for further information.
NOTE:
severe internal engine damage. If any coolant is needed to be added to the system please contact an authorized dealer.
Your vehicle has been built with an improved engine coolant (OAT coolant conforming to MS.90032) that allows extended maintenance intervals. This engine coolant (antifreeze) can be used up to ten years or 150,000 miles (240,000 km) before replacement. To prevent reducing this extended mainte- nance period, it is important that you use the same engine coolant (OAT coolant conforming to MS.90032) throughout the life of your vehicle.
Please review these recommendations for using Organic Additive Technology (OAT) engine coolant (antifreeze) that meets the requirements of FCA Material Standard MS.90032. When adding engine coolant (antifreeze):
NOTE:
The cap must be fully tightened to prevent loss of engine coolant (antifreeze), and to ensure that engine coolant (anti- freeze) will return to the radiator from the coolant expansion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if there is any accu- mulation of foreign material on the sealing surfaces.
Used ethylene glycol-based coolant (antifreeze) is a regu- lated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for your community. To prevent ingestion by animals or children, do not store ethylene glycol-based coolant in open containers or allow it to remain in puddles on the ground. If ingested by a child or pet, seek emergency assistance immediately. Clean up any ground spills immediately.
The level of the coolant in the pressurized coolant bottle should be between the “MIN” and “MAX” range on the bottle when the engine is cold.
7
The radiator normally remains completely full, so there is no need to remove the cap unless checking for coolant freeze point or replacing engine coolant (antifreeze). Advise your service attendant of this. As long as the engine operating temperature is satisfactory, the coolant bottle need only be checked once a month. When additional engine coolant (antifreeze) is needed to maintain the proper level, it should be added to the coolant bottle. Do not overfill.
NOTE:
When the vehicle is stopped after a few miles/kilometers of operation, you may observe vapor coming from the front of the engine compartment. This is normally a result of mois- ture from rain, snow, or high humidity accumulating on the radiator and being vaporized when the thermostat opens, allowing hot engine coolant (antifreeze) to enter the radiator.
If an examination of your engine compartment shows no evidence of radiator or hose leaks, the vehicle may be safely driven. The vapor will soon dissipate.
In order to assure brake system performance, all brake system components should be inspected periodically. Refer to the “Maintenance Plan” in this section for the proper maintenance intervals.
With disc brakes the fluid level can be expected to fall as the brake linings wear. However, an unexpected drop in fluid level may be caused by a leak and a system check should be conducted.
Refer to “Fluids And Lubricants” in “Technical Specifica- tions” for further information.
7
The fluid level of the master cylinder should be checked when performing under the hood service or immediately if the brake system warning lamp indicates system failure.
If necessary, add fluid to bring level within the designated marks on the side of the reservoir of the brake master cylinder. Be sure to clean the top of the master cylinder area before removing cap.
(Continued)
It is important to use the proper transmission fluid to ensure optimum transmission performance and life. Use only the manufacturer’s specified transmission fluid. Refer to “Fluids And Lubricants” in “Technical Specifications”. It is important to maintain the transmission fluid at the correct level using the recommended fluid. No chemical flushes should be used in any transmission; only the approved lubri- cant should be used.
The manufacturer strongly recommends against using any special additives in the transmission. Automatic Transmis- sion Fluid (ATF) is an engineered product and its perfor- mance may be impaired by supplemental additives. Therefore, do not add any fluid additives to the transmis- sion. Avoid using transmission sealers as they may adversely affect seals.
The fluid level is preset at the factory and does not require adjustment under normal operating conditions. Routine fluid level checks are not required, therefore the transmis- sion has no dipstick. An authorized dealer can check your transmission fluid level using special service tools.
If you notice fluid leakage or transmission malfunction, visit an authorized dealer immediately to have the transmission fluid level checked. Operating the vehicle with an improper fluid level can cause severe transmission damage.
Under normal operating conditions, the fluid installed at the factory will provide satisfactory lubrication for the life of the vehicle.
Routine fluid and filter changes are not required. However, change the fluid and filter if the fluid becomes contaminated (with water, etc.), or if the transmission is disassembled for any reason.
For normal service, periodic fluid level checks are not required. When the vehicle is serviced for other reasons the exterior surfaces of the axle assembly should be inspected. If
gear oil leakage is suspected inspect the fluid level. Refer to 7
“Fluids And Lubricants” in “Technical Specifications” for further information. This inspection should be made with the vehicle in a level position.
For all 2500/3500 Model axles, the fluid level should be 1/ 4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on the
9.25 in front, 11.5 in rear axle, and 12.0 in rear axle.
Refer to “Fluids And Lubricants” in “Technical Specifica- tion” for further information.
NOTE:
The presence of water in the gear lubricant will result in corrosion and possible failure of differential components. Operation of the vehicle in water, as may be encountered in some off-highway types of service, will require draining and refilling the axle to avoid damage.
Limited-Slip Differentials DO REQUIRE limited slip oil additive (friction modifiers).
NOTE:
Slight noise and mild shuddering may be evident while turning a vehicle with limited slip differential on concrete or dry pavement. These conditions should be considered normal operation of the limited slip differential.
Refer to the “Maintenance Plan” for the proper maintenance intervals.
Use only the manufacturer's recommended fluid. Refer to “Fluids And Lubricants” in “Technical Specifications” for further information.
This fluid level can be checked by removing the filler plug. The fluid level should be to the bottom edge of the filler plug hole with the vehicle in a level position.
Refer to the “Maintenance Plan” in this section for the proper maintenance intervals.
