Coolant Pump Weep Hole - 3.5L, 3.7L
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
For 3.5L and 3.7L, the coolant pump is located under the engine front cover mounted to the block. A weep hole is provided on the front left side of the engine behind the generator. It is adjacent to a 13.5 mm (0.531 in) cup plug. This plug and the weep hole create a reservoir for normal coolant seepage and evaporation. Every coolant pump will have some leakage past the dynamic mechanical seal. Dampness and crusting around the weep hole is acceptable and an expected result of normal engine operation. Coolant spray or leakage amounts great enough to puddle should be addressed.
