There is no need to re-flush the system. Sounds like you have done a good job. Re-filling through the hose was a good job. Let me know if it is fully cured.
Turn heater controls to maximum and set air discharge to instrument panel vents. Turn blower to high. Fill cooling system with 50/50 mixture of coolant and water. Pause several minutes for circulation. Start engine and allow to idle. While engine is idling, feel for hot air at instrument panel vents. If air discharge remains cool and coolant temperature gauge does not move, coolant level is low.
Stop engine and allow it to cool. Top off coolant as necessary. Start engine and allow it to idle until normal operating temperature is reached. Hot air should discharge from instrument panel vents. Coolant temperature gauge should maintain a stable reading in middle of range. Upper radiator hose should feel hot to touch. Stop engine and allow it to cool. Top off coolant as necessary. Check for coolant leaks.
Some models are equipped with a coolant level indicator light on instrument panel. If coolant level indicator flashes an additional 1.0-1.5 qts. (.95-1.42L) of coolant mixture can be added to overflow bottle.
On 3.9L engine, open engine coolant fill cap. On 3.0L engine, open air bleed located in upper radiator hose inlet pipe. On all engines, open heater air bleed located in left rear corner of engine compartment. Add coolant to degas bottle until no more coolant can be added. On 3.0L close air bleed on upper radiator hose inlet when coolant begins to escape.
On all engines, install degas bottle cap. On 3.9L engine, install engine coolant fill cap. Start engine and set heater controls to MAX heat position. Close heater air bleed when a steady stream of coolant comes from bleed during idle. Allow engine to idle for 5 minutes. Add coolant as necessary to maintain cold fill MAX mark on degas bottle.
Increase engine speed to 2000 RPM on 3.9L engine, or 1500 RPM on 3.0L engine. Hold for 3-5 minutes, or until hot air comes from heater. Allow engine to idle. Recheck to ensure hot air is still coming from heater. Set temperature control to 75 F (24 C) and allow engine to idle for 2 minutes. Shut engine off, and allow to cool.
After engine has cooled, add coolant to degas bottle as necessary to bring level to cold fill MAX mark.
