What does Blue Devil Fix?
It permanently repairs cooling system leaks such as radiators,
heater cores and freeze plugs. It also permanently repairs most
blown head gaskets, cracked heads, warped heads and cracked blocks.
My car is overheating. Will Blue Devil correct this?
No. All cooling related problems must be solved first. Defective fan switch,
fan clutch, clogged or restricted cores, heavy scale and sediment deposits,
or systems jellied from antifreeze must all be properly functioning
and capable of adequately cooling the vehicle.
How does it work?
Blue Devil reacts to temperature differential created by airflow at the leak point.
That temperature differential is the catalyst for the chemicals in Blue Devil
to react and form its chemical weld.
