2020 SUZUKI JIMNY Engine

INSPECTION AND MAINTENANCE
It is important to keep the engine oil at the correct level for proper lubrication of your vehicle's engine. Check the oil level with the vehicle on a level surface. The oil level indication may be inaccurate if the vehicle is on a slope. The oil level should be checked either before starting the engine or at least 5 minutes after stopping the
engine. The handle of the engine oil dipstick is col­ored with yellow for easy identification.
6-25
Pull out the oil dipstick, wipe the oil off with a clean cloth, insert the dipstick all the way into the engine, and then remove it again. The oil on the stick should be between the upper and lower limits shown on the stick. If the oil level indication is near the lower, limit, add enough oil to raise the level to the upper limit.
NOTICE
Failure to check the oil level regularly could lead to serious engine trouble due to insufficient oil.
Refilling
Open Close tr-------~,
• \lc----------,1/.
52RM60020
Remove the oil filler cap and pour oil slowly through the filler hole to bring the oil level to the upper limit on the dipstick. Be careful not to overfill the oil. Too much oil is almost as bad as too little oil. After refilling, start the engine and allow it to idle for about a min­ute. Stop the engine, wait about 5 minutes and check the oil level again.

Changing engine oil and filter
Drain the engine oil while the engine is still warm.

1) Remove the oil filler cap. 2) Place a drain pan under the drain plug. 3) Using a wrench, remove the drain plug and drain the engine oil.
A CAUTION
The engine oil temperature may be high enough to burn your fingers when the drain plug is loosened. Wait until the drain plug is cool enough to touch with your bare hands.
Tightening torque for drain plug: 35 Nm (3.6 kg-m, 25.8 lb-ft)
A WARNING
Engine oil can be hazardous. Chil­dren and pets may be harmed by swallowing new or used oil. Keep new and used oil and used oil filters away from children and pets. Repeated, prolonged contact with used engine oil may cause skin can­cer. Brief contact with used oil may irri­tate skin. (Continued)
INSPECTION AND MAINTENANCE
A WARNING
(Continued) To minimize your exposure to used oil, wear a long-sleeve shirt and moisture-proof gloves (such as dish­washing gloves) when changing oil. If oil contacts your skin, wash thor­oughly with soap and water. Launder any clothing or rags if it is with oil. Recycle or properly dispose of used oil and oil filters.
4) Reinstall the drain plug with new gas­ket. Tighten the plug with a wrench to the specified torque.

To tighten the oil filter properly, it is important to accurately identify the position at which the filter gasket first contacts the mounting surface.
5) Tighten the filter as specified below from the point of contact with the mounting surface (or to the specified torque) using an oil filter wrench.
Tightening torque for oil filter: 3/4 turn or 14 Nm (1.4 kg-m, 10.3 lb-ft)
NOTICE
To prevent oil leakage, check that the oil filter is tight, but do not over­tighten it.

Refill with oil and oil leakage check
1) Pour oil through the filler hole and install the filler cap. For the approximate capacity of the oil, refer to "Recommended fuel / lubricants and capacities (approx.)" in "SPECIFI­CATIONS" section. 2) Start the engine and carefully check the oil filter and the drain plug for leakage. Run the engine at various speeds for at least 5 minutes. 3) Stop the engine and wait about 5 min­utes. Check the oil level again and add oil if necessary. Check for leakage again.
NOTICE
When replacing the oil filter, it is recommended that you use a genu­ine SUZUKI replacement filter. If you use an aftermarket filter, check that it is of equivalent quality and follow the manufacturer's instruc­tions. • Oil leakage from the periphery of the oil filter or drain plug indicate incorrect installation or gasket damage. If you find any leakage or are not sure that the filter has been properly tightened, have the vehi­cle inspected by a SUZUKI dealer.
Engine coolant
Selection of coolant
NOTICE
SUZUKI LLC: Super (Blue) coolant; This coolant is already diluted to the proper percentage. Do not dilute with distilled water additionally. Doing so may result in the possibility of freez­ing and/or overheating coolant.
To maintain optimum performance and durability of your engine, use SUZUKI gen­uine coolant or equivalent.
NOTE: If you use the engine coolant other than the SUZUKI LLC: Super (Blue) for replace­ment, follow the schedule of SUZUKI LLC: Standard (Green). To see the detail of the maintenance schedule, refer to "Periodic maintenance schedule" in this section.
This type of coolant is the best for cooling system for the following reasons: • The coolant helps maintain proper engine temperature. It gives proper protection against freez­ing and boiling. It gives proper protection against corro­sion and rust.
INSPECTION AND MAINTENANCE
Failure to use the proper coolant can dam­age your cooling system. Your SUZUKI dealer can help you select the proper cool­ant.
NOTICE
To avoid damaging your cooling sys­tem: Always use a high quality ethylene glycol base non-silicate type cool­ant diluted with distilled water at the correct mixture concentration. Check that the proper mix is 50/50 coolant to distilled water and in no case higher than 70/30. Concentra­tions greater than 70/30 coolant to distilled water will cause overheat­ing conditions. Do not use straight coolant nor plain water (except "SUZUKI LLC: Super {Blue)"). . • Do not add extra inhibitors or addi­tives. They may not be compatible with your cooling system. Do not mix different types of base coolants. Doing so may result in accelerated seal wear and/or the possibility of severe overheating and extensive engine/automatic transmission damage.

INSPECTION AND MAINTENANCE
NOTE: SUZUKI highly recommends the use of ECSTAR brand coolant. ECSTAR has been specially formulated for your SUZUKI product and contributes to the desired vehicle performance and ideal driving experience.
Coolant level check
Check the coolant level at the reservoir tank, not at the radiator. With the engine cool, the coolant level should be between "FULL" and "LOW" marks.
Adding coolant
,A WARNING
Swallowing engine coolant can cause severe injury or death. Inhaling cool­ant mist or vapors or getting coolant in your eyes could result in severe injury. • Do not drink antifreeze or coolant solution. If swallowed, do not induce vomiting. Immediately con­tact a poison control center or a physician. • Avoid inhaling coolant mist or hot vapors. If inhaled, remove to a fresh air area. (Continued)
