Radiator
REMOVAL
1) Drain cooling system.
2) Remove radiator shroud.
3) Disconnect water hoses from radiator.
4) With automatic transmission (A/T) vehicle, disconnect addi-
tional two fluid hoses from radiator.
Place some container under radiator to receive A/T fluid
which will flow out when hose is disconnected.
5) Install radiator protection board to between radiator and
cooling fan.
6) Remove radiator after removing two bolts (1).
INSPECTION
If the water side of the radiator is found excessively rusted or cov-
ered with scales, clean it by flushing with the radiator cleaner
compound.
This flushing should be carried out at regular intervals for scale or
rust formation advances with time even where a recommended
type of coolant is used. Periodical flushing will prove more eco-
nomical.
Inspect the radiator cores and straighten the flattened or bent
fins, if any. Clean the cores, removing road grimes and trashes.
Excessive rust or scale formation on the wet side of the radiator
lowers the cooling efficiency.
Flattened or bent fins obstruct the flow of air through the core to
impede heat dissipation.
Radiator flushing interval recommended
Two years
INSTALLATION
Reverse removal procedures.
NOTE:
Refill cooling system with proper coolant referring to
“Coolant” and “Cooling System Flush and Refill” in
this section.
With automatic transmission vehicle, fill A/T fluid up to
specified level. For procedure to check A/T fluid and its
level, refer to “Changing Fluid” in Section 7B.
After installation, check each joint for leakage.
