Quick answer: Replacing the water pump on a 2011–2019 Ford Explorer with the 3.5L V6 typically costs $1,900–$3,500, and $3,000–$5,000 if you also replace the timing chain, guides and tensioners (recommended). The pump itself is cheap; the cost comes from 10–14 hours of labor, because the pump sits inside the engine, driven by the timing chain.

Estimates updated October 2026. Labor at $100–$200 per hour.
| Job | Parts | Labor | Typical total |
|---|---|---|---|
| Water pump only (independent) | $150 – $400 | $1,500 – $2,800 | $1,900 – $3,200 |
| Water pump + timing chain, guides, tensioners | $500 – $1,100 | $1,600 – $3,000 | $2,500 – $4,200 |
| Same, plus cam phasers | $900 – $1,600 | $1,800 – $3,200 | $3,000 – $5,000 |

The same internal-pump design is used on the 3.5L/3.7L V6 in other Ford and Lincoln models of the era, such as the Flex, Taurus, Edge, MKX, MKT and MKS.
Why this repair is so expensive (and urgent)
When the pump’s internal seal fails, coolant can leak into the engine oil instead of outside the engine. Coolant in the oil destroys bearings, so a pump failure can turn into engine replacement ($5,000–$8,000+). Some cars also leak through a weep hole behind the pulley, which is hard to see.
Symptoms of a failing internal water pump
- Coolant level dropping with no visible leak.
- Milky or light-brown oil, or oil level rising.
- Overheating or temperature gauge spikes.
- Sweet smell or coolant drips near the front of the engine.
- Codes such as P0016 (crank/cam correlation) from stretched timing chains, often linked to coolant-contaminated oil.
Ask a shop for a cooling system pressure test and an oil analysis if you suspect a leak.
Should you replace it before it fails?
Many owners replace the pump preventively around 100,000–120,000 miles, especially if they plan to keep the Explorer. It’s expensive, but much cheaper than an engine. At minimum, check coolant and oil regularly.
Is it worth fixing?
On a well-kept Explorer worth $8,000 or more, usually yes. On an older Explorer with coolant already in the oil, a used or remanufactured engine may be the better option; see Head Gasket Replacement Cost for comparison and use the Repair or Replace Calculator.
How to save money
- Get quotes from independent Ford specialists; dealer prices vary widely.
- Do the timing chain parts at the same time to avoid paying the labor twice.
- Check for extended warranty coverage.
