2) Inspection for radiator clogging
To inspect the radiator cores to see if they are
clogged with fur or rust,remove the radiator cap
and check for transparency of the coolant,and for
rust or fur formation around the radiator throat
inside the radiator.
If some rust or fur has formed or the coolant
transparency is very poor,the radiator should be
cleaned.
a. Cleaning the radiator inside.
-Place the radiator upside down and supply
pressurized water from a faucet to the lower tank,
draining through the upper tank,as shown in the
figure to wash out accumulated deposits.
-Clean with a detergent
When cleaning the radiator with a detergent,
follow the instructions given by its manufacturer.
Different detergents have different characteristics.
b. Cleaning the radiator exterior
-
Cleaning the net (wire mesh)
After the tractor has been operated in dusty
conditions,check the net daily and clean it if
necessary.
-Cleaning the radiator cores
Clean the radiator cores by applying water spray
or compressed air so as to for a right angle with
the radiator cores,moving water application in
parallel.
Note:
When cleaning the radiator cores with
Pressurized water ,be sure to apply it at a right
angle to the cores. Slanted application might
deform their cooling fins.
3) Visual inspection of the exterior parts
When the radiator exterior is corroded,cracked,or
badly damaged,replace the radiator.Also replace
damaged or fatigued water hoses.
Retighten loose hose clamps securely if water is
leaking through the hose clamps securely ,or
replace them if necessary.
4) Inspection of the radiator cap.
