Engine Cooling System Specifications & Drive Belt Routing Dodge Ram Van III

All Except Concorde & Intrepid

Air in system will collect under radiator cap. As engine reaches operating temperature, coolant and any trapped air will enter reserve tank. As engine cools, a vacuum will be created which will draw only coolant into cooling system. After engine has gone through a warm-up and cooling cycle, run engine until it again reaches operating temperature. Ensure coolant in reserve tank is at warm coolant mark on reserve tank or dipstick.

Concorde & Intrepid

1. Attach one end of a 48" (1219 mm) long by.250" (6.35 mm) inside diameter clear air bleed hose to the air bleed valve. (Scheme 1) Air bleed valve is located on lower intake manifold. Air bleed hose is used to prevent coolant from contacting accessory drive belt when bleeding cooling system.
2. Route air bleed hose away from accessory drive belt, drive pulleys and electric cooling fan. Place other end of air bleed hose in coolant container. Open air bleed valve.
3. Remove cap and install Funnel (8195) in coolant reservoir bottle. (Scheme 1) Use clip attached to funnel to pinch overflow hose closed. (Scheme 1) The overflow hose fits between the 2 chambers on the coolant reservoir bottle. CAUTION: Manufacturer recommends using only Mopar® Extended Lift Coolant or equivalent with a 50/50 concentration coolant and distilled water. This coolant contains corrosion inhibitors that permit extended service drain intervals. DO NOT mix coolants. If coolant other than Mopar® Extended Life Coolant or equivalent is used, the service drain interval will be reduced.
4. Pour a 50/50 concentration of coolant and distilled water into the large area on the funnel. The smaller area on the funnel will allow the air to escape when filling cooling system. Slowly fill cooling system until a steady stream of coolant flows from air bleed hose.
5. Close air bleed valve. Continue filling cooling system until coolant level is at the top of the funnel. Remove clip from overflow hose. This will allow coolant in the funnel to flow into the overflow chamber on the coolant reservoir bottle.
6. Remove funnel from coolant reservoir bottle. Install cap on coolant reservoir bottle. Remove air bleed hose. The engine cooling system will bleed any remaining air into the coolant reservoir bottle within about one hour of normal driving. As a result, coolant level in the coolant reservoir bottle will decrease.

Note. Coolant reservoir bottle contains 2 chambers. Coolant will normally be in the inside (smaller) of the 2 chambers. The outside chamber (overflow chamber) is only to recover coolant in the event of an overheat condition and should normally be empty during normal operation. If coolant exists in the outside chamber during normal operation, disconnect end of overflow hose at neck of coolant reservoir bottle. Lower overflow hose and allow coolant to drain from outside chamber into a coolant container until outside chamber is empty. Reinstall overflow hose.

5.9L DIESEL ENGINE

For bleeding procedures on 5.9L diesel, see appropriate 12-valve or 24-valve engine article in ENGINES. DO NOT operate engine while filling cooling system.

BELT ADJUSTMENT

Note. For belt routing on models not covered in this article, information was not available. See underhood label for proper belt routing.

Belts should be adjusted to proper tension using belt tension gauge. See appropriate BELT ADJUSTMENT SPECIFICATIONS table. Some models may be equipped with an automatic belt tensioner. Ensure serpentine belts are routed properly. (Scheme 6)- (Scheme 15).
