4. Caulk tank in speci®ed sequence with Tool.
+Use pliers in the locations where Tool cannot be used.
5. Make sure that the rim is completely crimped down.

INSPECTION
1. Apply pressure with Tool.
Speci®ed pressure value:
98 kPa (0.98 bar, 1.0 kg/cm
2, 14 psi)
WARNING:
To prevent the risk of the hose coming undone while under
pressure, securely fasten it down with a hose clamp.
Attach a hose to the oil cooler as well.
2. Check for leakage.
