TIM :

hello,

FILLING - GAS ENGINES

The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion protection. In order to maintain the required protection for these components and cooling system performance, only use the appropriate fluid when servicing the vehicle. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

Clean cooling system prior to refilling.

1. Install cylinder block drain plugs. Coat the threads with Mopar® Thread Sealant with Teflon.

2. Close radiator petcock.

3. Fill cooling system with coolant,

4. Fill coolant reserve/overflow tank to MAX mark on bottle.

5. Start and operate engine until thermostat opens (upper radiator hose warm to touch).

6. If necessary, add coolant to the coolant recovery container. This is done to maintain coolant level between the MAX and MIN marks. The level in the coolant recovery container may drop below the MIN mark after three or four warm-up and cool-down cycles.

i would check to see if the waterpump is working -- it sounds like we have a circulation concern
