Rislone Cooling system for coolers, stops leaks. 16.9 fluid ounces, guaranteed Xtreme Cool stops overheating and reduces temperature.

Have a large diesel generator for work fitted to the back of a lorry and a stone had gone through the rad. Chucked this in and hey presto it stopped leaking in half an hour. Very easy to use

Urunu aldim talimatlara uygun bir sekilde kullandim ama urun iyi degildi

Had a leak, loosing about 1L of coolant a month. Poured half of this into the rad and followed rest of instructions to the letter. Had to top up after a week or so but haven't had to since. Keep checking under rad filler cap and no scummy deposits visible and coolant level remains constant, now 8 weeks in. Probably should get the system drained and the leak cause fixed but tempted to run the car into the ground.

This was my third and final attempt after trying other well known named products.It solved it straight away and has not even let a drip out in 2 months.Best product for the job.

Had a slow leak in system that had struggled to find. Smell with engine burning off coolant when starting. Used as described and have had no problem since. Worked well for small leak
