Cooling System Supplemental Coolant Additive (SCA) - Test/Add
Use the 8T-5296 Coolant Conditioner Test Kit
or use the 4C-9301 Coolant Conditioner Test Kit
in order to check the concentration of the SCA.
Refer to the Operation and Maintenance Manual for
more information on conventional coolant/antifreeze
cooling system maintenance.
Water and SCA
NOTICE
Do not exceed the recommended eight percent sup-
plemental coolant additive concentration.
Test the concentration of the SCA with the 8T-5296
Coolant Conditioner Test Kit. Refer to the Operation
and Maintenance Manual, “Water/Supplemental
Coolant Additive (SCA)” topic (Maintenance
Section). Refer to the Operation and Maintenance
Manual, “Conventional Coolant/Antifreeze Cooling
System Maintenance” topic (Maintenance Section).
S·O·S Coolant Analysis
S·O·S coolant samples can be analyzed at your
Caterpillar dealer. S·O·S Coolant Analysis is a
program that is based on periodic samples.
Level 1
Level 1 is a basic analysis of the coolant. The
following items are tested:
•
Glycol Concentration
•
Concentration of SCA
•
pH
•
Conductivity
The results are reported, and recommendations
are made according to the results. Consult your
Caterpillar dealer for information on the benefits of
managing your equipment with an S·O·S Coolant
Analysis.
Add the SCA, If Necessary
NOTICE
Do not exceed the recommended amount of sup-
plemental coolant additive concentration. Excessive
supplemental coolant additive concentration can form
deposits on the higher temperature surfaces of the
cooling system, reducing the engine’s heat transfer
characteristics. Reduced heat transfer could cause
cracking of the cylinder head and other high temper-
ature components. Excessive supplemental coolant
additive concentration could also result in radiator
tube blockage, overheating, and/or accelerated water
pump seal wear. Never use both liquid supplemental
coolant additive and the spin-on element (if equipped)
at the same time. The use of those additives together
could result in supplemental coolant additive concen-
tration exceeding the recommended maximum.
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the pres-
sure.
1. Slowly loosen the cooling system filler cap in
order to relieve the pressure. Remove the cooling
system filler cap.
Note: Always discard drained fluids according to
local regulations.
2. If necessary, drain some coolant from the cooling
system into a suitable container in order to allow
space for the extra SCA.
3. Add the proper amount of SCA. Refer to the
Operation and Maintenance Manual for more
information on SCA requirements.
4. Clean the cooling system filler cap. Inspect the
gaskets of the cooling system filler cap. If the
gaskets are damaged, replace the old cooling
system filler cap with a new cooling system filler
cap. Install the cooling system filler cap.
