INSTALLATION
Install in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Check for leaks of engine coolant using radiator cap tester adapter [SST: EG17650301 (J33984-A)] and
radiator cap tester (commercial service tool). Refer to CO-38, "
LEAK CHECK" .
Start and warm up engine. Visually Check if there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapNBS003KL
Check valve seat of radiator cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.
Pull negative-pressure valve to open it, and make sure that it
close completely when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.
Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester adapter
(SST) and the radiator cap tester (Commercial service tool),
apply engine coolant to the cap seal surface.
Replace radiator cap if there is an unusualness.

CAUTION:
When installing a radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorNBS003KM
Check radiator for mud or clogging. If necessary, clean radiator as follows:
CAUTION:
Be careful not to bend or damage the radiator fins.
When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radi-
ator shroud and horns. Then tape the harness and electrical connectors to prevent water from
entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.
Use compressed air lower than 490 kPa (5 kg/cm2 , 71 psi) and keep distance more than 30 cm (11.8
in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.

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. Standard height “H” : 8.0 - 8.4 mm (0.315 - 0.331 in)
