Ford Fiesta: Intake Air Distribution and Filtering - 1.6L EcoBoost (132kW/180PS) – Sigma / Charge Air Cooler (CAC) Cleaning. General Procedures
Activation
-
NOTE:
Do not use a high-pressure power washer to clean the CAC (Charge Air Cooler) or damage to the CAC may occur.
NOTE:
Drain all contaminates such as coolant, fuel and oil prior to cleaning the CAC.
NOTE:
Thoroughly clean the joint clamp areas as well as
the turbocharger connection, engine connection and the CAC connections,
using metal brake parts cleaner.
Lay the CAC flat with the inlet and outlet ports pointing up.
-
NOTE:
Plug or cap the CAC openings prior to agitating.
-
Add an appropriate amount of commercially available
detergent cleaner such as Simple Green Pro HD, or equivalent to the CAC.
Follow the manufacturer's directions for cleaning. Fill the CAC to 40%
of its volume with water.
-
Raise one end of the CAC and agitate it by hand for at least 5 minutes.
-
Raise the opposite end of the CAC and agitate it by hand for at least 5 minutes.
-
Drain the CAC.
-
Flush the CAC thoroughly with clean water.
-
Repeat Steps 1 through 6 until no contaminates are found in the flush water.
-
Allow the CAC to air dry.
-
NOTE:
The following leak test steps must be performed prior to installing the CAC.
NOTE:
Use a commercially available kit, such as the
Johnson Manufacturing Company Charge Air Cooler Test Set Part No.
351-CAS, or equivalent.
Install the commercially available CAC cooler tester on
the CAC following the manufacturer's installation instructions.
-
Tighten the clamps to 5 Nm (44 lb-in).
-
WARNING:
Never exceed the specified pressure. Excessive
pressure may cause the test adapter to blow off or may damage the charge
air cooler (CAC). Failure to follow this instruction may result in
serious personal injury.
Slowly apply air pressure to 150 kPa (22 psi).
-
Let the CAC stand for a few minutes and note any loss in pressure.
-
Release the air pressure.
-
Repeat Steps 12 through 14 as many times as necessary to
verify the readings. The reading is considered verified when 3
consecutive tests show approximately the same pressure drop.
-
If the pressure loss exceeds 10 kPa (1.5 psi) per minute, install a new CAC.
