Coolant mix clar­i­fied

Canal Boat - - Letters -

I have just read your is­sue ( CB, Feb) and in Ask the Ex­perts Tony Brooks states that we will not hon­our our war­ranty if the coolant is not at a mix of 50/50.

We state that the coolant mix should be 33-50 per­cent mix, the main rea­son for the anti-freeze is for anti-cor­ro­sive prop­er­ties, not to raise the boil­ing point of the cool­ing wa­ter. We have not stated that it must be main­tained at 50 per­cent just be­tween 33 and 50 per­cent; no anti-freeze will in­val­i­date the war­ranty be­cause of cor­ro­sion.
