On the 2011-2019 Ford Explorer, the 3.5L V6 engine (both naturally aspirated and EcoBoost versions) features an internal water pump located under the engine front cover. When this pump fails, it can leak coolant internally into the engine crankcase, contaminating the oil and potentially causing catastrophic engine damage if not caught immediately.

On the 2011-2019 Ford Explorer, the Power Transfer Unit (PTU) on AWD-equipped Explorers is prone to premature failure due to its proximity to the exhaust pipe and catalytic converter, causing overheating. Fluid leaks from disconnected vent hoses are common, and if fluid level drops too low, the PTU can fail completely, disabling the AWD system.

This issue also affects: BMW 5 Series, BMW 6 Series, BMW 7 Series

Common Symptoms

Fluid leak underneath vehicle near front of transmission
Whining or grinding noise from front of drivetrain
AWD system malfunction warning
Shuddering during acceleration
Burning smell from drivetrain area
Complete loss of AWD functionality

How to Fix

Check and reconnect PTU vent hose if disconnected. Replace PTU seals if leaking. Complete PTU replacement if internal damage has occurred. Install aftermarket PTU cooler to prevent overheating. Regular PTU fluid changes every 30,000 miles.
