SERVICE INFORMATION
Engine antifreeze in more than 50% concentration has been found to adversely affect the life and performance of the engine block heater. High
phosphate content in the antifreeze forms a scale around the heating element of the block heater, causing the temperature to rise, with subsequent failure
of the seals. Therefore, for best results it is recommended that you use a concentration no greater than 50% antifreeze and 50% water.
