Changan JL476ZQCA (JL family, 1.0–2.0)

Changan's 1.5 turbocharged four — in the CS75 and Eado.

It is Changan's own engine, developed in-house rather than licensed, and it is among the commonest turbo petrols on Chinese roads while being almost undocumented in English.

It is a conventional modern direct-injected turbo four and its faults are that family's: intake-valve carbon is expected at mileage because no fuel washes over the valves, and it presents as a rough idle and a hesitant pull-away that respond to cleaning.

The turbocharger's oil feed is what the service interval is really protecting, and on an engine this small making this much power that is the failure mode rather than routine advice. Establish the engine code rather than searching the model, because the same vehicles were sold under several names in export markets.

This page answers for the Changan JL engine codes generally, and the cars listed below run 1.0 to 2.0 litres — JL372, JL476, JL478 and JL486 among them. The description above is the 1.5 turbo. The naturally aspirated members share the family construction and not its boost, so the turbocharger paragraph is not about all of them.
