Ford Focus Mk3 Starter Motor: Specs, Fitment & Common Faults

How to tell a failing starter motor from a flat battery, and what actually fits your specific engine.

Generation covered: this guide is for the third-generation Focus, built 2011–2018 (commonly the 2014–2018 registered examples still in daily use). The newer Mk4 Focus (2018–) uses different part numbers throughout — check your V5C logbook or VIN if you're unsure which generation you have.

Often Confused With a Battery Problem

A Ford Focus Mk3 that won't start gets blamed on the battery first, more often than not correctly — but a healthy battery paired with a failing starter motor produces some genuinely similar symptoms, which leads plenty of people to replace the wrong part first.

Before you buy: starter motor specification varies by engine size and, on some versions, whether the car has stop-start technology. Always confirm against your VIN before ordering.

OEM Part Number: CV6T-11000-GE

Accuracy note: starter part numbers vary significantly by engine and, importantly, by whether the car has stop-start — confirmed numbers below cover the 1.0 EcoBoost, the most common engine across this generation. If your Focus uses a different engine, confirm the number directly with a Ford dealer or parts supplier using your VIN.

Other engines (1.5/1.6/2.0 petrol, 1.5/2.0 diesel)Not independently confirmed — check via VIN

One genuinely important distinction: cars fitted with Ford's stop-start system use a heavier-duty starter motor built to withstand far more start cycles than a conventional one, since the engine restarts every time the car pauses in traffic. Fitting a standard, non-stop-start starter to one of these cars will wear out quickly. Check your handbook or ask your supplier to confirm whether your specific VIN has stop-start before ordering.

Ford Focus Mk3 Starter Motor: What It Does

On the Ford Focus Mk3, the starter motor uses electrical power from the battery to physically turn the engine over, initiating the combustion cycle. On cars with stop-start systems, this component works considerably harder than on older designs, since the engine restarts far more frequently — which is why stop-start cars often use a reinforced starter motor rather than a standard unit.
