ISSUE
Some 2001-2003 Escape 3.0L vehicles may exhibit a low coolant warning indicator lamp illuminated. This may be caused by a low coolant level, even if
it appears there is significant coolant in the degas bottle. Analysis of coolant degas bottles indicate that bottle replacement may not be necessary.
Adjusting the coolant to the proper level may be all that is required to correct the condition.
ACTION
The following Service Procedure provides tips to help in veritying proper coolant levels. Additional diagnostic and service information can be found in
the appropriate Workshop Manual Section 303-03.
SERVICE PROCEDURE
PROPER INSPECTION AND ADJUSTMENT OF COOLANT LEVEL IN THE DEGAS BOTTLE
There are four (4) different cells within the Escape degas bottle. The front cells of the degas bottle are not a good visual indicator of proper coolant level,
as these cells will always give the appearance of being full (Figure 1). The actual COLD FILL RANGE is the larger cell with the fill cap, just below the
seam. It can be difficult to see if not properly examined.
If the vehicle is HOT when inspecting, the coolant level should be at the bottle seam (minimum) or above the seam by 1/2 inch, well above the LOW
mark. When hot, if the coolant level is not at least to the top of the COLD FILL RANGE (seam), there is a possibility of illuminating the low coolant
lamp when the vehicle cools down and the coolant is drawn back into the engine cooling system.
DIAGNOSIS
Engine Hot Or Cold Coolant Warning Indicator Lamp Not Illuminated (OFF):
1.
If the coolant level is found to be below the COLD FILL RANGE (seam) add coolant, tighten pressure cap and return vehicle to customer.
