Toyota 1G-FE

2.0 L · inline-6 · naturally aspirated · petrol · 1988–present

Also known as: 1g-fe, 1g-ge, 1g-gte, 1g, 2.0 straight-six toyota, 1g-geu, 1g-eu

Toyota's 2.0 straight-six — in the Mark II, Chaser, Crown, the early Lexus IS and the Supra A70.

A two-litre six is an unusual thing and it explains the engine. Six very small cylinders make it exceptionally smooth and not particularly powerful, which is exactly what a Japanese tax class rewarded. It is smoothness bought with complexity, and everything about servicing it reflects that.

It is belt-driven on the earlier engines and chain-driven later, which is the first thing to establish on a car of unknown specification — the two have completely different maintenance consequences.

Its recurring items are ignition and breathing: coil packs and the distributor on early engines, a carboned throttle body, and inlet gaskets that harden and leak unmetered air. The 1G-GTE twin-turbo is a different proposition and is not what is in a saloon. Documentation outside Japan is thin, so the engine code rather than the model is what to search.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
