4. REMOVAL OF THE RADIATOR
1) Release the clamp and remove the upper hose.
2) Release the clamp and remove the lower hose.
3) Release the hose clamp and remove the water
drain hose.
Note:
- Refer to the paragraph”SEPARATION OF THE
ENGINE AND THE FRONT AXLE BRACKET
in chapter 2 for operation up to this step.
-When removing the radiator, take care not to
damage the radiator cores and the condenser.
5. INSPECTION OF EACH PART
1) Inspection for radiator water leaks.
Water leaks are liable to occur at the fitting
portion between the upper tank and the core
section or between the lower tank and the core
section .If any water leak should occur there,
repair the leak by soldering.Besides making a
visual check,a more complete inspection
should be accomplished as follows:
a. Leak test with compressed air.
Place the radiator as shown in the figure. Close
the openings for water inlet and with something
like a rubber plug and apply compressed air
(1㎏ f/㎠ or 14.2psi) through the drain pipe
into the radiator.
Excessively compressed air may damage the
cores, so perform the air delivery carefully,
watching the pressure gauge. Water leaks are
inspected by watching for rising air bubbles.
b.Leak test with a radiator cap tester
With the inlet and outlet pipes plugged up and the
radiator filled with water,replace radiator cap
with a radiator cap tester as shown in the figure.
Pump up the pressure in the radiator to the
specified value and check to see if there are any
leaks in the radiator.
When the radiator is water-tight,the pressure
indicated on the pressure gauge does not increase,
but if there are leaks,the pressure decreases.
This tester is also applicable for leak tests
for the whole cooling system,not only for the
radiator. The test method is the same as
mentioned above.
