CSF worked like charm. Very fast it completely removed rust from our Scania R420 and Volvo FH12

Our company operates 6 280kw motors equipped with cooling jacket. We noticed that motor temperature was high and after inspection we found coolant flow very low. We used CSF and after one hour the coolant flow was unrestricted. A boroscope examination confirmed that there wasn't any sign of rust. We adapted CSF to our maintenance procedures.

My 90hp Yamaha had clogged water cooling passages. My only solution was to dismantle everything and clean manually. I came across CSF and decided to give it a try. I was really surprised by the results. CSF cleaned everything in just 2 hrs. no clogging no rust no residues. Thank you for your product you saved me allot of time. I plan to use CSF again just before winter storage.

My fiat punto 2001 had huge problem with overheating. Finally had to take to mechanic to repair a blown head gasket. The overheating problem insisted and the cabin heating had limited functionality. A friend (truck driver) suggested to used CSF. After using it motor temperature is low even in hot days with bad traffic. Cabin heating works again. I was ready to sale my car for spares since the cost or repair was higher than my car value. Thank you guys great product.
