⚠️ Attention: If you hear a metallic knock at the top of the engine when cold, which disappears after warming up, this may indicate a stretched timing chain or worn tensioner. Don't delay diagnosis.
1.8 l MR18DE engine: power for active driving
An alternative to the weaker 1.5-liter unit was the engine MR18DE volume 1798 cc. cm. This powerplant is equipped with a CVTC variable valve timing system on the intake shaft only and develops up to 122 horsepower. Thanks to the increased working volume, MR18DE provides more confident acceleration and better throttle response, especially when overtaking on the highway.
Structurally, this engine is distinguished by an aluminum cylinder block with cast iron liners, which ensures high maintainability if boring or liner replacement is necessary. The lubrication system here also has its own characteristics, including the presence of an oil cooler on some modifications, which is critical for preserving service life during intensive use.
- 🚀 Higher torque compared to 1.5-liter equivalent
- 🛠️ Increased piston group resource with timely oil changes
- 📉 Slightly increased fuel consumption, but quite acceptable for the class
However, it is worth remembering that MR18DE more demanding on the quality of engine oil and filters. The use of low-quality consumables can lead to coking of the piston rings and loss of compression. Regularly checking the oil level and condition should become a habit for you.
⚠️ Attention: On MR series engines, there is often a problem with the crankshaft oil seal leaking from the gearbox side. When replacing a clutch or variator, be sure to check the condition of this seal.

Typical faults and solutions
Despite their reputation as reliable units, engines Nissan have a number of characteristic problems that you should be aware of before purchasing or during operation. One of the most common problems is a dirty throttle body, which leads to unstable idle speed and poor engine starting.
The CVTC variable valve timing system can also cause problems. Wear of the phase shifter gear leads to the appearance of a characteristic “crackling” sound when starting a cold engine. If you hear this sound, you need to replace the camshaft gear, otherwise it may cause the chain to jump and cause serious consequences.
- 🔋 Malfunctions of the ignition coils, leading to misfire and engine tripping
- 🚿 Leaking valve cover gasket, which is often accompanied by the smell of burning oil
- 💧 Wear and tear of the water pump and radiator of the cooling system, requiring timely replacement
Particular attention should be paid to the cooling system. Engine overheating even for a short time can lead to deformation of the cylinder head and the need for costly repairs. Always monitor the temperature sensor readings and the condition of the radiator fan.

Maintenance and routine maintenance
Proper maintenance is the key to long engine life Nissan Cube. The manufacturer recommends changing the engine oil and oil filter every 10,000 kilometers or once a year, whichever comes first. Synthetic oils with a viscosity of 5W-30 or 0W-20, meeting API SN standards or higher.
The air filter should be replaced every 20,000 kilometers, and more often in dusty urban environments. A clean filter ensures proper mixture formation and protects the cylinders from fine dust. Also, do not forget to check the condition of the spark plugs; their service life is about 40,000 - 60,000 kilometers.
☑️ Scheduled engine maintenance
When replacing attachment belts, it is also important to check the condition of the tension rollers. Their wear can cause the belt to whistle or break, which will cause the generator and power steering pump to stop. In some cases, it is necessary to replace the timing belt (if it is installed in your modification, although more often there is a chain), but for chain motors it is critical to monitor the condition of the tensioner.
⚠️ Attention: When changing the oil, be sure to use the original oil filter. Cheap analogues often do not provide adequate filtration and can quickly clog, leading to oil starvation.
