COOLING SYSTEM 14-4
COOLING CIRCUIT
INSPECTION
• Remove the radiator cap.
• Connect the tester
î›§
1 to the filler.
• Give a pressure of about 120 kPa (1.2 kgf/cm
2
, 17.0 psi) and
see if the system holds this pressure for 10 seconds.
• If the pressure would fall during this 10-second interval, it
means that there is a leaking point in the system. In such a
case, inspect the entire system and replace the leaking com-
ponent or part.
$ WARNING
Engine coolant may be harmful if swallowed or if it
comes in contact with the skin or eyes. If engine cool-
ant gets into the eyes or contacts the skin, flush the
eyes or wash the skin thoroughly, with plenty of water.
If engine coolant is swallowed, induce vomiting and
call a physician immediately.
Do not open the radiator cap when the engine is hot,
as you may be injured by escaping hot liquid or vapor.
$ WARNING
When removing the radiator cap tester, put a rag on
the filler to prevent spouting of engine coolant.
CAUTION
Do not allow the pressure to exceed the radiator cap
release pressure, or the radiator can be damaged.
