4. Make sure that the rim is completely crimped down.
5. Make sure that there is no leakage. Refer to CO-19, "
INSPECTION" .
INSPECTION
1. Apply pressure with radiator cap tester adapter (SST) and radia-
tor cap tester (commercial service tool).
WARNING:
To prevent the risk of hose coming undone while under
pressure, securely fasten it down with hose clamp.
CAUTION:
Attach hose to A/T fluid cooler to seal its inlet and outlet.
2. Check for leakage by soaking radiator in water container with
the testing pressure applied.Standard height “H” : 8.0 - 8.4 mm (0.315 - 0.331 in)
