INSPECTION
1. Apply pressure with radiator cap tester adapter (SST) and radia-
tor cap tester (commercial service tool).
provide used radiator and connect it to tested radiator using
radiator hoses as shown in the figure.
NOTE:
The used radiator should be tested beforehand to confirm it
has no leakage. If used one is not available, it is possible to
use new service part as a radiator testing 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.
