How to Service and Repair the Cooling Hose on Ford Mustang?

The technician should start coolant line service and repair by draining engine coolant first. Start by removing the upper intake manifold followed by disconnection of the bypass hose from the bypass tube. First remove the bolt that attaches the bypass tube to the water pump before disconnecting the quick connect fitting and removing bracket bolts along with the bypass tube. New O-ring seals must be installed on the water bypass tube during assembly since cutting the O-ring will lead to engine coolant leakage. Use premium engine coolant to apply on the O-ring seal while cleaning the O-ring sealing surfaces found on the cylinder heads. To install the elements you need to follow the opposite steps of removal.
