Strainers save your cooling system
By PaulM from Portsmouth, RI

A good heavy duty strainer will go a long ways to keeping crud and guck out of your engine cooling system. The see thru feature makes it easy to keep tabs on the trapped slime and debris.

Bottom Line Yes, I would recommend to a friend
