Crown Vic/ Grand Marquis Intake Manifold Replacement. Testing and repairing a coolant leak.

Today I show you how I tested and repaired the coolant leak on this Mercury Grand Marquis. This vehicle had the common issue with the intake manifold where the manifold cracks causing the coolant passage to leak into the valley of the engine. Unfortunately for this vehicle just repairing the upper radiator hose and thermostat was not enough. DISCLAIMER.
