Oil and Chemical Type

OIL AND CHEMICAL TYPE DESCRIPTION

Engine oil
Type: Recommended oil

WARNING:

Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.
Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the "FUEL LINE SAFETY PROCEDURE " to prevent the fuel from spraying.
- Fuel may cause irritation if it comes in contact with skin and eyes.
- If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.
A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before draining fuel, make sure to discharge static electricity by touching the vehicle body.
Connect a ground wire to the oil-resistant fuel hose for draining fuel and the vehicle because the oil-resistant fuel hose for draining fuel may become electrically charged.

CAUTION:

Touching the end of the fuel injector by hand or pressing it to an object may cause a malfunction. Be very careful when handling the end of the fuel injector.
When the fuel distributor is removed, air tightness of the fuel injectors will be lost. Always replace the stopper ring, O-ring, back-up ring, spacer, and teflon seal on all four fuel injectors with new ones when the fuel distributor is removed.
Do not remove the fuel pressure sensor from the fuel distributor.

Complete the "BEFORE SERVICE PRECAUTION". (See BEFORE SERVICE PRECAUTION .)
Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US) .)
Remove the intake manifold. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
Remove the high pressure fuel pipe. (See HIGH PRESSURE FUEL PUMP INSPECTION .)
Remove in the order indicated in the table.
Install in the reverse order of removal.
Complete the "AFTER SERVICE PRECAUTION". (See AFTER SERVICE PRECAUTION .)
