Test for SCA Concentration
Heavy-Duty Coolant/Antifreeze and SCA
NOTICE
Do not exceed the recommended six percent supple-
mental coolant additive concentration.
Use a Coolant Conditioner Test Kit in order to check
the concentration of the SCA.
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 correct amount of SCA. Refer to the
Operation and Maintenance Manual, "Refill
Capacities and Recommendations" 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.
