Coolant Condition Check

Remove pressure relief cap or radiator cap (8100) following described precautions. Check coolant for dirty or rusty appearance.

If coolant does not appear dirty or rusty, check coolant level and concentration as described in the following procedures.

If coolant appears dirty or rusty, drain the cooling system, recycle coolant using Rotunda Coolant Recycler 181-00003, flush and refill.

Check coolant concentration for recommended protection level using Rotunda Battery and Antifreeze Tester 014-R1060 or equivalent. If concentration is low, partially drain the cooling system and add 100 percent antifreeze solution such as Premium Cooling System Fluid E2FZ-19549-AA or -B (in Oregon F5FZ-19549-CC), recycled coolant or equivalent meeting Ford specification ESE-M97B44-A, to obtain the recommended protection level.
