Cooling circuit inspection
Before removing the radiator and draining the engine coolant, inspect the cooling circuit for tightness.
- Remove the fuel tank. (6-3)
- Remove the left frame head cover. (9-6)
- Remove the radiator cap 1 and connect the tester 2 to the filler.
Warning: Do not remove the radiator cap when the engine is hot.
- Give a pressure of about 110 kPa (1.1 kgf/cm², 15.6 psi) and see if the system holds this pressure for 10 seconds.
- If the pressure should 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 component or part.
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.
