Under The Hood And Vehicle

WARNING: This page is about a different car, the 2019 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.

The maintenance items listed here should be checked periodically (e.g., each time you check the engine oil or refuel).

Item

Reference

Windshield washer fluid 

Check that there is adequate fluid in the tank.

--

Engine coolant level 

Check the coolant level when the engine is cold.

System Inspection

Radiator and hoses 

Check the front of the radiator and clean off any dirt, insects, leaves, etc., that may have accumulated. Make sure the hoses have no cracks, deformation, deterioration or loose connections.

--

Brake fluid level 

Make sure that the brake fluid level is between the MAX and MIN lines on the reservoir.

Inspection 

Battery 

Check the fluid level in each cell. It should be between the MAX and MIN lines. Vehicles operated in high temperatures or under severe conditions require frequent checks of the battery fluid level.

Removal and Installation

Engine drive belts 

Make sure that no belt is frayed, worn, cracked or oily.

Checking Drive Belts - Early Production  or Checking Drive Belts - Late Production 

Engine oil level 

Check the level on the oil level gauge after parking the vehicle on a level spot and turning off the engine.

Inspection 

Power steering fluid level and lines 

Check the level on the dipstick with the engine off. Check the lines for improper attachment, leaks, cracks, etc.

Inspection 

Exhaust system 

Make sure there are no loose supports, cracks or holes. If the sound of the exhaust seems unusual or there is a smell of exhaust fumes, immediately locate the trouble and correct it.

Inspection 

Underbody 

The underbody is frequently exposed to corrosive substances such as those used on icy roads or to control dust. It is very important to remove these substances, otherwise rust will form on the floor pan, frame, fuel lines and around the exhaust system. At the end of winter, the underbody should be thoroughly flushed with plain water, being careful to clean those areas where mud and dirt can easily accumulate.

--

Fluid leaks 

Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has been parked for a while. Water dripping from the air conditioner after use is normal. If you should notice any leaks or gasoline fumes are evident, check for the cause and correct it immediately.
