Cooling and electrical systems
Cooling system in Nissan Juke has its own characteristics related to the need for efficient heat removal from the turbine and engine in confined spaces. Expansion tank Usually located on the front right side, which allows you to easily monitor the antifreeze level. However, the reservoir cap is under high pressure, so opening it on a hot engine is strictly prohibited.
The electrical part under the hood is represented by a complex network of harnesses and connectors. The fuse and relay box, located in the engine compartment, is responsible for operation cooling fans, fuel pump and absorber. When checking electrical wiring, always use a multimeter and ensure the integrity of the wire insulation.
The battery requires regular cleaning of the terminals from oxides, especially in winter. Poor contact can lead to engine starting problems and electronic malfunctions. Also check the condition generator and the tension of its belt, if provided for by the design.
⚠️ Attention: When working on the cooling system, always allow the engine to cool completely. Opening the expansion tank cap on a hot engine can result in the release of boiling liquid and serious burns.
Maintenance and inspection schedule
To Nissan Juke served for a long time, it is necessary to strictly adhere to the maintenance regulations. This is not just a formality, but a guarantee that all components and assemblies will operate as normal. Oil change and filters should be done every 10-15 thousand kilometers or once a year, depending on operating conditions.
At each maintenance, be sure to conduct a visual inspection of the engine compartment for:
- 🔍 Oil, antifreeze or brake fluid leaks;
- 🔍 Cracks and wear of rubber pipes and hoses;
- 🔍 Conditions of drive belts and tension rollers;
- 🔍 Integrity of electrical connectors and wire insulation.
Pay special attention crankshaft seals and camshaft, since replacing them requires significant labor costs. Replacing gaskets promptly will save you money in the future.
