Removal And Installation

WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Make sure the ignition switch is in the OFF position prior to working on the electronic engine controls.

Turn the ignition switch to the OFF position.

WARNING: Never remove the pressure relief cap 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 or result in personal injury. To avoid having scalding hot coolant or steam blow out of the degas bottle when removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while the pressure is released from the cooling system. When certain all the pressure has been released, (still with a cloth) turn and remove the pressure relief cap. Failure to follow these instructions can result in personal injury.

Relieve the cooling system pressure. Disconnect and plug or cap the engine vent hose and radiator vent hose.

CAUTION: With the engine cold, fill vehicles with a yellow fill level decal to within the yellow cold fill range shown on the decal. If the decal is missing, fill the degas bottle only to the molded line. The correct fill level on these vehicles is between the molded line and 15 mm (0.59 inch) below the line. These fill levels will allow for coolant expansion. Overfilling the degas bottle may result in damage to the pressure cap, which can cause the engine to overheat.

To install, reverse the removal procedure.
