Standard Procedure - Coolant Level Check
WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Do not remove coolant bottle pressure cap for routine coolant level inspections.
The coolant bottle provides a quick visual method for determining the coolant level without removing the pressure cap. With the engine cold, the level of the coolant in the coolant bottle (Fig 1) should be between the MIN and MAX lines on the bottle.
