1A1-12 GENERAL ENGINE INFORMATION
Leakage Test1. Warm the engine up to normal operating temperature.
2. Disconnect the negative battery cable.
3. Remove the spark plugs.
4. Check the coolant level by opening the coolant surge tank cap and replenish if insufficient.
5. Open the engine oil filler cap.
6. Connect the tester to air pressure line and adjust the scale of tester.
7. Install the connecting hose to spark plug hole.
9. Connect the connecting hose to tester and measure the leakage volume after blowing up 5bar of compressed air. Notice Measure the leakage volume in the completely opening condition of throttle valve by pulling the acceleration cable.
10. Perform the pressure test according to the firing order.
Notice Firing Order : 1 - 5 - 3 - 6 - 2 - 4
11. Compare the leakage pressure with the specifications. 8. Position the piston of No.1 cylinder at TDC by rotating the
crankshaft.

GENERAL INFORMATION
CLEANLINESS AND CARE An automobile engine is a combination of many machined, honed, polished and lapped surfaces withtolerances that are measured in the ten-thousanths ofan inch. When any internal engine parts are serviced,care and cleanliness are important. A liberal coating of enigne oil should be applied to friction areas during
assembly, to protect and lubricate the surfaces on initialoperation. Proper cleaning and protection of machinedsurfaces and friction areas is part of the repairprocedure. This is considered standard shop practice even if not specifically stated. Whenever valve train components are removed for
service, they should be kept in order. They should beinstalled in the same locations, and with the same matingsurfaces, as when they were removed. Battery cables should be disconnected before any majorwork is performed on the engine. Failure to disconnectcables may result in damage to wire harness or other electrical parts. ON-ENGINE SERVICE Caution: Disconnect the negative battery cable before removing or installing any electrical unit, or when a tool or equipment could easily come in contact with exposed electrical terminals.Disconnecting this cable will help prevent personalinjury and damage to the vehicle. The ignition mustalso be in LOCK unless otherwise noted. Notice:
Any time the air cleaner is removed, the intake
opening should be covered. This will protect against accidental entrance of foreign material, which could follow the intake passage into the cylinder and cause extensive damage when the engine is started.
