4. CAUTION WHEN SERVICING THE ENGINE
1) Cleaness
Engine has a lot of precisely machined (grinding, polishing, lapping) surfaces. Thus, there should be
great cautions for cleaness when servicing the engine components. Apply the engine oil on the sliding
surfaces when assemblying the components. Every component should be disassembled and
reassembled in accordance with the correct sequences. Before servicing the engine, the negative cable
should be diconnected from the battery. Otherwise, some electric or electronic components could be
damaged.
2) Servicing
Before service work, be sure to disconnect battery negative (-) terminal to prevent damages by bad
wire and short.
To prevent the foreign material from getting into engine cylinder, cover the inlet of air cleaner if the
air cleaner has been removed.
(1) Lifting up the vehicle
Always keep the safety precautions.
To prevent the vehicle from rolling down, put the chocks under the tires (when using a 4-post lift).
Make sure to support the correct lifting points (when using a 2-post lift) -

(2) Exhaust system

(3) Cautions before service
Scalding hot coolant and steam could be blown out under pressure, which could cause serious injury.
Never remove the coolant reservoir cap when the engine and radiator are hot.
