The car has been on sale for over thirty years, and is always a welcome guest in any garage. Even used models sell like hot cakes thanks to affordable prices, rich tuning options and good technical performance. Production on the conveyor was carried out until 2018, and during this time, car owners saw several options for the Nexia engines.

General information

Auto experts are of the opinion that the Nexia engine is quite unpretentious, reliable, although not without flaws. Despite the fact that the EGR valve somewhat reduces the engine power at the bottom, contributes to the contamination of the engine intake, the car is popular, as in the early days of sales. On average, the resource of the power unit on these cars reaches 250,000 km.

About the range of engines

The manufacturer gave the line 4 variants of the power unit. The volume of the Nexia engine in production until 2008 was 1.5 liters with a different number of valves: these are sixteen valves on the A15MF product, and on the G15MFinstalled 8.

The situation changed in 2015 when the developers came up with a new eight-valve model A155MS with the same volume. A little later, drivers could choose another modification - F16D3. The volume has been increased to 1.6 liters. How are the motors different?

Interesting features of the Daewoo Nexia engine

In this practical collection, adapted to Russian conditions, the Daewoo Nexia G15MF engine was endowed with 75 horsepower and 100 Nm of torque.

In the restyled version, drivers were able to experience greater opportunities while enjoying 80 hp. s.

The variant under consideration had similar features with the Opel C16NZ, but this is an apparent phenomenon. What makes it different?

• The eight-valve has a different cylinder diameter, a different piston group.
• Another ebb crankshaft made to drive an oil pump.
• In the cylinder head, a metal fitting is used as a plug, there is a difference in the cylinder head and the combustion chamber.

The main advantage of the Nexia engine is that the driver can accelerate to 175 km/h for a hundred kilometers in just 12 seconds. In the city, fuel is consumed in the amount of approximately 9 liters. Driving dynamism dictates its own rules and higher consumption. Avoiding overheating, not overloading, changing the oil in time, you can make sure that the unit will last a long time and flawlessly, revealing its full potential. Fill in a surrogate lubricating fluid, do not call in services for maintenance, depending on the condition of the machine -a sure way to the occurrence of defects leading to costly repairs. What about other powertrain options?

A brief educational program on F16D3

The unit is a Nexia engine, 16 valves of which allow you to freely travel along the highway at a decent speed. The manufacturer equipped it with a resource of 250 thousand km. The nuance of this device is the likelihood of valve failures when the timing belt breaks: at high crankshaft speeds, considerable damage is expected, because the pistons will hit the valves. This motor is also installed on the Chevrolet Cruze, Lacetti, Aveo. The design is based on distributive fuel injection. What does this give the car owner?

1. Prolongs engine life.
2. Good fuel economy.
3. Exhaust gases are less toxic.
4. Failures rarely occur when driving in extreme conditions: rain, ice.

Of the minuses, one can single out the complexity of the installation scheme, expensive repairs and replacement of electronic elements, the need for repair work only by highly qualified specialists. What problems can occur on the road?

Common faults

Eight-valve products often leak oil due to defective valve covers. You should not drive on rough roads when it is not justified: the right "cushion" of the Nexia 8 engine may break, and auto mechanics advisekeep this area under close control. CV joints do not suffer as long as their covers are safe and sound. It is difficult to understand the condition of the hinge from the plastic cover. If moisture gets under the cover, it fails. Each time, after driving 70 thousand km, it is worth carefully inspecting this section. What problems can you expect from a 16 valve?

1. Toxicity standards have been reduced due to the ingress of exhaust gases into the intake tract and their afterburning, but soon carbon deposits form on the valves, and the lubricant loses its purpose, and the engine begins to draw in exhaust.
2. Poor-quality fuel leads to clogging of the valve and the engine itself.
3. Lack of lubricant can be recognized by the clatter of the hydraulic lifter and valves. Loads on the power section will inevitably provoke a breakdown and impossible repair of the engine.

Many motorists use tuning techniques to improve dynamism and remove the catalyst, change the release. These two main factors prevent the Nexia engine from functioning normally. Nexia maintenance should be done on time, engine problems should not be triggered, then it is quite possible to carry out any mileage on different routes for many years.
