ENGINE OVERHEATING AND/OR LOSS OF A/C
PERFORMANCE

FORD:
2005 Escape

ISSUE
Some 2005 Escape vehicles built between 01/02/04 and 05/22/04 may exhibit an overheating condition. This condition may be due to a loss of engine coolant from the degas hose. The degas hose may come into contact with the front end accessory drive (FEAD) belt, damaging the hose.

The vehicle may also exhibit a loss of A/C performance. In some cases, the customer may only notice the loss of A/C. The PCM will disable the A/C compressor if the engine temperature reaches 230° F (110° C) or higher (ECT PID). Ensure the cooling system is full and operating properly before replacing any A/C or climate control components.

ACTION
Replace the degas hose with revised longer hose. Route the revised hose around and below the radiator drain petcock boss (Figures 1 and 2). Be sure to fasten the standoff clip included with the hose to the drain petcock boss.



The FEAD belt should also be replaced if there is any indication the belt has been contaminated with engine coolant. Prior to installing the new belt be sure to clean all pulleys with soap and water. If the pulley cleaning operation is not performed the new belt may become noisy.

2005 TRIBUTE - ENGINE OVERHEATING AND /
OR LOSS OF A/C PERFORMANCE

APPLICABLE MODEL(S)/VINS
2005 Tribute 3.0L built between 01/02/04 through 05/22/04 production

DESCRIPTION
Some 2005 Tribute V-6 models built between 01/02/04 and 05/22/04 may exhibit an overheating condition. This condition may be due to a loss of engine coolant from the degas hose (connects radiator to the overflow bottle). The degas hose may come into contact with the front end accessory drive (FEAD) belt, damaging the hose. The vehicle may also exhibit a loss of A/C performance.

In some cases, the customer may only notice the loss of A/C. The PCM will disable the A/C compressor if the engine temperature reaches 230 F (110 C) or higher (ECT PID). Ensure the cooling system is full and operating properly before replacing any A/C or climate control components.

Customers having this concern should have their vehicle repaired using the following repair procedure.




REPAIR PROCEDURE
WARNING:
^ Never remove the pressure relief cap under any conditions while the engine is operating or when the cooling system is hot. Failure to follow these instructions can result in damage to the cooling system or engine and/or personal injury. To avoid having scalding hot coolant or steam blow out of the cooling system, use extreme care when removing the pressure relief cap from a hot de-gas bottle.
^ Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly one turn (counterclockwise).
^ Step back while the pressure is released from the cooling system. When certain all the pressure has been released, remove the pressure relief cap (still with a cloth).

1. Verify concern.

2. Drain the cooling system according to Workshop Manual (Section 01-12B COOLING SYSTEM DRAINING FILLING AND BLEEDING).

3. Replace the degas hose.
NOTE:
^ The FEAD belt should also be replaced if there is any indication the belt has been contaminated with engine coolant.
^ Prior to installing the new belt be sure to clean all pulleys with soap and water. If the pulley cleaning operation is not performed the new belt may become noisy.

4. Re-fill and bleed the cooling system according to Workshop Manual (Section O1-12B COOLING SYSTEM DRAINING FILLING AND BLEEDING).
a. Allow engine to warm up to full operating temperature, confirm engine temperature reading on gauge and on-off cycling of cooling fans.
b. Inspect for leaks at both ends of the hose.
