COOLER BY-PASS VALVE (4R100) 

Removal & Installation 

1. Raise and support vehicle. Remove front cooler line from front Cooler By-Pass Valve (CBV), fitting. See 

Fig. 13 . Remove rear cooler line from rear CBV fitting. Remove front and rear CBV bolt cooler line case 
fittings. Clean and flush CBV. See appropriate OVERHAUL article. 

2. To install, reverse removal procedure. Check rubber coated sealing washers for damage. Replace as 

needed. Use sealant or threadlock meeting Ford specification WSK-M2G351-A5 and coat line case fitting 
threads. Install CBV with check ball at rear fitting. This allows fluid to flow in one direction only. Ensure 
that check ball moves freely. 

WARNING:

Vehicle is equipped with Supplemental Inflatable Restraint (SIR) system. 
When servicing vehicle, use care to avoid accidental air bag deployment. 
SIR system-related components are located in various locations 
throughout interior and exterior of vehicle, depending on application. Do 
not use electrical test equipment on or near these circuits. If necessary, 
deactivate SIR system before servicing components. See AIR BAG 
DEACTIVATION PROCEDURES article in GENERAL INFORMATION.

CAUTION: When battery is disconnected, vehicle computer and memory systems 

may lose memory data. Driveability problems may exist until computer 
systems have completed a relearn cycle. See COMPUTER RELEARN 
PROCEDURES article in GENERAL INFORMATION before disconnecting 
battery.

CAUTION: The electrical power to the air suspension system must be shut OFF prior 

to hoisting, jacking or towing an air suspension vehicle. This can be 
accomplished by turning OFF the air suspension switch located in the 
right kick panel area. Failure to do so may result in unexpected inflation or 
deflation of the air springs which may result in shifting of the vehicle 
during these operations.

NOTE:

Cooler By-Pass Valve (CBV) must be thoroughly cleaned and flushed out at this 
time. DO NOT lose rubber coated sealing washers when removing CBV cooler 
line case fittings.

CAUTION: Ensure CBV is properly back flushed. Use dry compressed air to 

remove excess solvent. If an overhaul is being performed, replace 
Oil-To-Air (OTA) cooler.

CAUTION: If cooler line case fitting is over-tightened, rubber coated sealing 

washers and/or cooler line case fittings can be damaged, causing a 
transmission fluid leak.
