What are the benefits of a COOLFILTER?
Besides the direct benefit of the engine running cooler by keeping the
radiator efficient, COOLFILTER saves inconvenience and expense by eliminating radiator clean-outs.
Does COOLFILTER need cleaning?
Most have operated for years without the need for cleaning.
However, we recommend cleaning annually, one week after fitting or disturbing cooling system parts or if engine temperature gauge is reading higher than normal.
Can COOLFILTER become restricted?
Not if it is maintained as recommended and cleaned as required.
Note that is strongly recommended that the system be professionaly cleaned before installation.
Can COOLFILTER cause corrosion?
No. It is made from a heat resistant material that will not react with any
known cooling system components.
Does COOLFILTER restrict coolant Flow?
The correct engine thermostat offers much more restriction even when fully open.
What is the life of a COOLFILTER?
With normal care in fitting and handling, it should last for several years.
However, prolonged exposure to sunlight will damage the filter.
