Are All 3.7L Ford Engines the Same?
No. The 3.7L was built in two layouts with different accessories, and only one of them has the internal water pump.

- Ford Mustang, 2011–2017

- Lincoln MKX, MKS, MKT, MKZ
- Mazda CX-9, Mazda 6
The 3.7L Ford Internal Water Pump Problem
Why transverse 3.7L engines get coolant in the oil
On transverse 3.7L applications, the water pump sits inside the engine behind the timing cover and is driven by the timing chain. When its seal fails, coolant leaks directly into the engine oil, which can wipe out the bearings if it isn't caught early. Replacing the pump on these engines is a major, labor-heavy job, which is why many owners choose a complete engine instead.
Fraser Advantage™ builds go further by installing a new timing cover and oil pan along with the upgraded block and updated heads, so you're not bolting old, coolant-soaked parts onto a fresh engine.

Know the warning signs
Common 3.7L Ford Engine Problems
The 3.7L Ford V6 is a strong naturally aspirated engine, but high mileage, timing system wear, overheating, oil leaks, coolant contamination and water-pump-related concerns lead to major repairs.
Water pump concerns
Transverse 3.7L applications use a timing-chain-driven internal water pump that can cause serious engine damage if coolant contaminates the oil.
Timing chain and guide wear
High-mileage engines develop startup rattle, timing noise, cam timing faults or drivability concerns.
Oil leaks
Valve cover gaskets, timing covers, oil pans and seals leak over time.
Overheating damage
Cooling system problems damage cylinder heads, gaskets and internal engine components.
Low compression and internal wear
Worn piston rings, valves, bearings or cylinder sealing surfaces lead to rough running and power loss.
Application-specific differences
Mustang, F-150, Transit, Edge, Lincoln and Mazda applications use different layouts and accessory configurations.
Diagnose first
Repair or Replace? Signs You Need a 3.7L Ford Engine
Some 3.7L Ford issues can be repaired externally, but severe timing failure, coolant contamination, overheating damage, low compression or internal engine wear make replacement the smarter long-term repair.
- Coolant contamination in the oil
- Timing chain noise, startup rattle or cam timing faults
- Persistent overheating or coolant loss
- Low compression or failed leak-down test
- Oil pressure warnings or metal in the oil
- Knocking, rattling or internal noise
- Heavy oil consumption or drivability concerns
- Replacement recommended by a licensed repair shop

Know the difference
Used 3.7L Ford vs. Low-Cost Rebuild vs. Fraser Remanufactured
A used 3.7L Ford engine may come from a donor with unknown mileage, previous overheating, timing chain wear, water pump concerns, poor maintenance history, oil leaks or internal damage. Even if it currently runs, hidden timing, coolant or bearing wear may already be developing. Instead of gambling on another high-mileage used engine, you receive a professionally renewed replacement backed by Fraser's powertrain-focused support.

Answers before you order
3.7L Ford Engine Replacement FAQs
Is the 3.7L Ford engine reliable?
Yes. It's a strong naturally aspirated DOHC V6. The main weak point is the internal water pump on transverse applications, which can put coolant in the oil. High-mileage engines also develop timing chain wear and oil leaks.
What vehicles used the 3.7L Ford engine?
2011–2017 Mustang, 2011–2014 F-150, 2015–2019 Transit, 2011–2014 Edge Sport, Police Interceptor, 2011–2015 MKX, MKS, MKT, 2013–2016 MKZ, 2008–2015 Mazda CX-9 and 2009–2013 Mazda 6. We confirm by VIN.
What are common 3.7L Ford engine problems?
Internal water pump failure on transverse engines, timing chain and guide wear, oil leaks, overheating, and low compression and internal wear.
