Premium 50 Cool Plus

cCastrol Premium Cool Plus 50 is a READY-TO-USE ethylene glycol based engine coolant containing a balanced mixture of organic acid and inorganic corrosion inhibitors specially designed to service the requirements of a broad range of heavy duty diesel engines, particularly those with wet sleeve cylinder liners. Castrol Premium Cool Plus 50 is a low silicate, phosphate and amine free formulation providing long service life and excellent corrosion protection for lead solder, aluminium, yellow metal and ferrous alloys. The inclusion of a number of corrosion inhibitors prevents corrosion occurring in the number of dissimilar metals found in modern engine cooling systems. Castrol Premium Cool Plus 50 meets or exceeds major industry coolant standards and is suitable for use in the majority of U.S., European and Japanese origin heavy duty diesel engines.

Application

Castrol Premium Cool Plus 50 has been used successfully for many years in a range of U.S., European and Japanese origin turbocharged and naturally aspirated diesel engines. It is particularly recommended for wet liner engines,operating in both on-highway and off-road environments and arduous city stop-start driving conditions. It is Castrol's prime recommendation for all US heavy duty diesel engine cooling systems.

Conditions of Use

Castrol Premium Cool Plus 50 is a pre-mixed, READY-TO-USE coolant and should be added to cooling systems as a top up or when effecting a complete system change. DO NOT dilute further. Castrol Premium Cool Plus 50, as supplied, contains sufficient inhibitors to enable it to be used as an initial fill fluid without the need for an initial charge of a Supplementary Coolant Additive (SCA).

Advantages

• Balanced hybrid formulation of organic acid and conventional inhibitors guarantees performance in a wide range of diesel engines
• Excellent corrosion protection and freeze protection down to -37 degC
• Controls cavitation corrosion of wet sleeve type cylinder liners
• Does not require an initial charge of Supplemental Coolant Additive (SCA), however SCAs may be added as part of a planned maintenance schedule.
• Compatible with most commercial SCAs. Compatible with all conventional hoses, gaskets, seals and plastics used in heavy duty engine cooling systems
