  • Cooling system related problems are the #1 reason for roadside failure?
  • Overheated engines can cause costly engine repairs?
  • That the proper pH level is as important in radiator coolant as it is in a swimming pool?

Have you experienced...
  • Coolant temperature increase?

Overtime, the protection provided by your coolant decreases. The Castle Cooling System Service effectively cleans deposit build-up from your cooling system and extends its life. A safe, effective cleaning formula is added to the old coolant to remove tough organic deposits in the cooling system. It is also compatible with all types of coolant.



Castle Cool Flo™ specially formulated conditioner containing a balanced combination of inhibitors is added to the fresh coolant. This prevents corrosion and coolant breakdown. It is registered and approved by the U.S. government (Military Spec #6850-01-085-4717). When used in conjunction with regular cooling system maintenance, Castle Cool Flo™ helps prevent premature failure of cooling system components.

Finally, a cooling system sealer, composed of refined organic fibers, is added to prevent seepage and seal leaks in the radiator and block.
