ACTECO D-V VT Engine

ACTECO 2.0 (SQR484F) – Experiences, issues, fuel consumption and buying used

Introduction: A Chinese heart with Austrian pedigree

The engine in question, known as ACTECO 2.0 (often under the code SQR484F), represents a turning point for Chery. This is not a simple “copy” of old Japanese engines, but a power unit developed in cooperation with the renowned Austrian engineering company AVL. The goal was to build a robust engine that meets the standards of the time, yet remains simple to manufacture and maintain.

You will most often find it in the Chery Fora (A21), which was sold on some markets as the Vortex Estina or Speranza A516. Although on paper it looks like a modern 2.0 petrol engine of its era, in practice it behaves like a workhorse – it’s not very refined, but it can cover serious mileage with regular (and cheap) maintenance.

Reliability and maintenance

Belt or chain?

This engine uses a timing belt. Although some later ACTECO derivatives switched to a chain, the 2.0 unit in the Chery Fora (A21) relies on a belt. The system is relatively simple, but the quality of aftermarket parts on the market varies.

Major service and intervals

It is recommended to perform a major service every 60,000 km or 4 years, whichever comes first. Do not wait for the factory 80 or 100 thousand, because a snapped belt (or more often – a seized idler/tensioner) will cause piston-to-valve contact, a failure that often exceeds the value of the car.

Oil and oil consumption

The sump holds about 4.5 to 5 litres of oil (always buy a 5L can). The recommended grade is 5W-40 or 10W-40 for higher-mileage engines and warmer climates.

As for oil consumption, the ACTECO 2.0 is not known as an “oil burner” like some modern German engines, but it’s not immune either. Consumption up to 0.5 litres per 5,000 km is acceptable. If it uses more, the problem is usually valve stem seals or a leak at the valve cover gasket, which is a chronic issue – oil then enters the spark plug wells and can damage the leads and coils.

Spark plugs and coils

Spark plugs are standard and cheap. Replace them every 30,000 km (or more often if you run LPG). Neglected plugs are deadly for the ignition coils (this engine has either two double coils or individual coils, depending on model year), which are prone to overheating and cracking of the housing.

Most common failures

Besides oil leaks, owners are most troubled by sensors. The crankshaft position sensor and coolant temperature sensor can fail without warning, causing hard starting or stalling while driving. Also, engine mounts are often of poor quality, so vibrations are transmitted to the cabin after only 40–50 thousand kilometres. The thermostat is another weak point – it often sticks open, so in winter the engine does not reach operating temperature, which increases fuel consumption.

Specific parts (Costs)

Since this is an older-design naturally aspirated petrol engine, many expensive modern-age failures are avoided.

• Dual-mass flywheel: It doesn’t have one. The engine uses a classic solid flywheel. A clutch kit is relatively affordable, which is a big advantage in terms of maintenance.
• Injection system: Uses a conventional Bosch or Delphi MPI system. Injectors are robust and rarely cause problems unless extremely poor-quality fuel is used. Preventive ultrasonic cleaning at 100,000 km is advisable.
• Turbo and DPF: No turbocharger, no DPF filter, no AdBlue system. There is no EGR valve in the problematic form found on diesels (even if there is a recirculation system, it rarely clogs to the point of affecting engine operation).

Fuel consumption and performance

City driving

Here we come to the biggest drawback. The Chery Fora is not a light car, and the 2.0 engine is “old school”. Real-world city consumption is between 11 and 13 litres of petrol per 100 km. In winter and heavy traffic, this easily goes up to 14 litres.

Is it “lazy”?

With 130 hp and 180 Nm, you would expect decent performance. However, the engine is lazy at low revs (below 2500 rpm). To get it to pull, you have to rev it, which further increases noise and fuel consumption. For relaxed driving it is perfectly adequate, but overtaking requires dropping to a lower gear.

Motorway and cruising

On the motorway the engine feels more at home, but it lacks a sixth gear. At 130 km/h the engine spins at about 3,500 to 3,800 rpm (in fifth), which means the cabin is quite noisy. Consumption on the open road is around 7.5 to 8.5 litres, depending on how heavy your right foot is.

Additional options and modifications

LPG installation

YES, absolutely. This is an engine that feels like it was made for LPG. It has a metal or good-quality plastic intake manifold, hydraulic lifters (no valve clearance adjustment required) and indirect injection. Installing a sequential LPG system is routine, not expensive, and pays off very quickly given the high petrol consumption. There are no special requirements for valve lubrication systems.

Chiptuning (Stage 1)

Since this is a naturally aspirated engine, chiptuning makes no real sense. The gain would be in the range of 3 to 5 hp, which is imperceptible in everyday driving. It’s better to invest that money in quality spark plugs, leads and injector cleaning to restore factory power.

Gearbox

Types of gearboxes

This engine is most commonly paired with a 5-speed manual gearbox. There was also an option of a 4-speed automatic (of French origin, similar to the notorious AL4/DP0 design), but it is rarer.

Most common problems

The manual gearbox is a weak point of this model.

• Synchros: Synchros for second and third gear often fail, so the gearbox grinds when shifting quickly.
• Bearings: A whining noise from the gearbox is a sign that the bearings are on their way out. This can happen even at relatively low mileage (under 100k km).
• Shift feel: The gear lever is often imprecise and has a long throw (“like stirring soup”), which is more a characteristic than a fault.

The automatic gearbox is known for overheating and solenoid issues. If you are buying a used car with an automatic, be prepared for an overhaul that can cost more than the car itself (very expensive compared to the vehicle’s value).

Gearbox maintenance

Due to the lower material quality in the manual gearbox, it is recommended to change the gearbox oil every 40,000 to 50,000 km. It’s a small expense (about 2–3 litres of 75W-90 oil) and can significantly extend the life of the bearings and synchros. The cost of replacing the clutch kit is acceptable.

Buying used and conclusion

Buying a car with the ACTECO 2.0 engine is a double-edged sword. You get a lot of metal and equipment for little money, but you also inherit numerous small, annoying issues.

What to check before buying?

1. Diagnostics: Always scan for engine fault codes. The “Check Engine” light is often disabled (bulb removed or covered), while sensor errors are still present.
2. Oil leaks: Remove the plastic engine cover and look around the coils and spark plugs. If there is oil, the valve cover gasket is done.
3. Gearbox noise: Turn off the radio and listen to the gearbox in all gears while driving. Any whining or grinding is a red flag.
4. Suspension: Although not part of the engine, the suspension on these cars wears quickly, so check for knocking over bumps.

Final verdict

This engine is intended for drivers who want cheap transport, can fix small issues themselves or have a reliable and affordable mechanic. If you plan to install LPG, the ACTECO 2.0 can be an economical workhorse. However, if you are looking for refinement, quietness and sporty driving – look elsewhere.
