Any recommended radiator cleaners for a 1988 Caterpillar 953?

[IamBruce_Driver]

I am getting ready to service the cooling system on my 1988 Caterpillar 953 and would like to clean the radiator while I'm at it. Does anyone have a recommended radiator cleaner that works well on these machines?

I've had good luck with a quality heavy-duty radiator flush, but before adding any cleaner, I'd check the radiator fins and clean out any dirt, chaff, or debris packed between the cores. Sometimes a thorough external cleaning makes a bigger difference than the chemical flush itself on older machines like a 953.
