2006 Ford F-150: 3.5L EcoBoost coolant intrusion
2006 Ford F-150 · 13th (2015–2020 aluminum body) · 3.5L EcoBoost V6
How you’d notice
- Coolant disappearing with no puddle
- white smoke
- misfire on a cold start
- milky oil. 2015–2017 3.5 EcoBoost is the worst of this generation. A compression or leak-down test on a cold engine is the shop check.
Typical shop cost
| Repair | CAD | USD |
|---|---|---|
| Independent shop, parts and labour, before tax | $6,000–$12,000 | $4,500–$9,000 |
As of 2026. Ballpark, not a quote for the vehicle in the ad. CAD figures are Vancouver Island independent-shop ranges. USD is only printed when we’ve entered a US shop range — we don’t invent one.
Common window: 49,680–124,200 miles.
A lift, not a driveway glance. You pay the shop. First appointment of the morning so the engine is cold.
Walk away if
Coolant loss, milky oil, or a shop that will not leak-down a cold 3.5 EcoBoost
The bigger picture on this listing
This page is the year and model. The report is the vehicle in the ad. We do not publish, for this listing:
- whether these photos hide this job
- whether the asking price already assumes it
- tax on this price
- a named shop in this city — we only print phones we’ve checked
That’s the $34.99 CAD document. Homework, not an inspection.
