Cooling System Bleeding
- Attach one end of a 48" (120.0 cm) long by .250" (6.35 mm) inside diameter clear air bleed hose to air bleed valve. See Fig 1. On 2.7L, air bleed valve is located on coolant outlet on front of engine. On 3.5L, air bleed valve is located on lower intake manifold. On all models, air bleed hose is used to prevent coolant from contacting accessory drive belt when bleeding cooling system.
- 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.
- Remove cap and install Funnel (8195) in coolant reservoir bottle. Use clip attached to funnel to pinch overflow hose closed. See Fig 1. Overflow hose fits between 2 chambers on coolant reservoir bottle.CAUTION: Manufacturer recommends using only Mopar Extended Life Coolant 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 is used, service drain interval will be reduced.
- Pour a 50/50 concentration of coolant and distilled water into large area on funnel. Smaller area on funnel will allow air to escape when filling cooling system. Slowly fill cooling system until a steady stream of coolant flows from air bleed hose.
- Close air bleed valve. Continue filling cooling system until coolant level is at top of funnel. Remove clip from overflow hose. This will allow coolant in funnel to flow into overflow chamber on coolant reservoir bottle.
- Remove funnel from coolant reservoir bottle. Install cap on coolant reservoir bottle. Remove air bleed hose. Cooling system will bleed any remaining air into coolant reservoir bottle within about one hour of normal driving. As a result, coolant level in coolant reservoir bottle will decrease.NOTE: Coolant reservoir bottle contains 2 chambers. Coolant will normally be in the inside (smaller) chamber. 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 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.
