14-4 COOLING SYSTEM
COOLING CIRCUIT
INSPECTION
• Remove the radiator cap.
• Connect the tester
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.
* Engine coolant may be harmful if swallowed or if it
comes in contact with the skin or eyes. If engine
coolant 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 vomit-
ing 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.
When removing the radiator cap tester, put a rag on
the filler to prevent spouting of engine coolant.
Do not allow the pressure to exceed the radiator cap
release pressure, or the radiator can be damaged.
