2.
Remove the radiator cap, wet its seal with engine
coolant, then install it on the pressure tester.
Apply a pressure of 93 - 123 kPa (0.95 - 1.25 kgflcm' ,
14 - 18 psi).
Check for a drop in pressure.
lf the pressure drops, repiace the cap.

Testing
1.Wait until the engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the top oI the filler neck.
Attach the pressure tester to the radiator, and apply
a pressure of 93 - 123 kPa (0.95 - 1,25 kgf/cm' , 14 -
18 psi).
Inspect for engine coolant leaks and a drop in pres-
sure.
Remove the tester, and reinstall the radiator cap.
Check for engine oil in the coolant and/or coolant in
the engine oil.

4.Align the quick-connect fittings with the pipe. and
align the retainer locking pawls with the connector
grooves. Then press the quick-connect fittings onto
the pipe until both retainer pawls lock with a click-

NOTE: lf it is hard to connect, put a small amount of
new engine oil on the pipe end.
5. Make sure the connection is secure and that the pawls
are firmly locked into place; check visually and bypulling the connector.
Reconnect the battery negative cable, and turn the
ignition switch ON (ll). The fuel pump will run for
about two seconds, and fuel pressure will rise. Repeat
two or three times, and check that there is no leakage
in the fuel supply system.
