Coolant For Diesel Engines - Compare Products
Shell Rotella® extended life coolants (ELC) are formulated to:
- Provide high performance protection for today’s heavy-duty diesel engines
- Provide effective heat transfer, freeze and boiling protection
- Provide corrosion protection for the cooling system
NOTICE: Shell Canada Products recently learned of labelling and seal integrity issues affecting one US gallon/3.785 litre bottles of Rotella ELC Nitrite Free Pre-Diluted 50/50 (SKU #550057739). The recalled product does not currently meet regulated Canada Consumer Product Safety Act labelling requirements, and an identified discrepancy in packaging integrity has led to our decision to conduct a voluntary recall for this product and SKU only. For more information, visit Health Canada web site/Shell coolant recall page.
ELCs are designed for up an extensive service life, with NO need for SCAs, that provides overall reduction in cooling system maintenance. ELCs also offer complete cooling system component protection by helping to reduce water-pump failures, hard-water-scale deposits and silicate gel (the green goo you sometimes see). We understand consumers’ challenges and have designed a product portfolio to help make maintenance needs easier.
