NALCOOL PG Extended Life Heavy Duty Coolant

PG Extended Life Heavy Duty Coolant is a blue coloured, superior, fully formulated Hybrid technology propylene glycol based premixed engine coolant based on Nalcool 824 technology. This Hybrid technology coolant has the advantage of being more robust than both conventional and organic acid technology (OAT) engine coolants. This low silicate, phosphate and amine free product is recommended for use in automotive (aluminium compatible), light duty and heavy-duty diesel applications namely on-road truck, off-road mining, farm and marine. It provides excellent high temperature aluminium protection.

PG does not require an initial charge of supplemental coolant additives (SCAs) upon initial fill in heavy duty diesel applications as the product is specially formulated to protect heavy duty diesel wet sleeve liners and is compatible with heat rejecting aluminum surfaces.

  • Contains Propylene Glycol (PG)
  • Extended life – no requirement for SCA or coolant extender for up to 4 years, 12,000 hours or 1,000,000 km whichever comes first? Always follow OEM guidelines regarding coolant system maintenance.
  • Product is compatible with standard SCAs and PG coolant extenders
  • Low silicate and phosphate and amine free, is hard water compatible
  • Universal use, recommended for use in all vehicle types
  • Product is compatible with both conventional and OAT coolants (although to get maximum performance it is best to flush the old coolant and replace with Nalcool-PG Extended Life Heavy Duty Coolant)
