HOUSTON, TX – Shell is recalling selected batches of coolants that, while not sold in Canada, may have been purchased in the U.S. But anything already poured into a cooling system does not need to be replaced.

The recall includes one-gallon bottles and 55-gallon drums of Shell ROTELLA Ultra ELC 50/50 Pre-diluted Antifreeze/Engine Coolant and one batch (B2811293U063/30Sept15) of 55-gallon drums of Shell ROTELLA Ultra ELC Antifreeze/Coolant Concentrate because the products were undertreated with bitterant — an additive used to make them “unpalatable”.

“It is important to note that the lack of bitterant has no impact on product performance,” the company stresses in a release. They pre-diluted formulas also come with child-resistant closures and warnings on the label.

Shell ROTELLA Ultra ELC 50/50 Pre-diluted and Shell ROTELLA Ultra ELC Concentrate Antifreeze/Engine Coolants are used in on- and off-highway vehicles, and in marine, farm, mining and construction equipment.

Distributors, retailers and users are asked to remove these products from inventories, separate them from products for sale, and return or recycle. Those who already have some of the coolant should visit www.ROTELLA.com/productreturn to begin a claim process. Open products should then be taken to a local recycling facility or auto parts store to be recycled.
