RMI-25 Cooling System Treatment - 250 ml Reviews

RMI-25 is a cooling system treatment that makes engines run cooler and protects the whole system. It lowers coolant temperature by 7°C or more, cleans scale and rust, and guards against corrosion, electrolysis and cavitation. It lubricates water-pump seals and doubles hose life. You can run it with straight water, distilled water or conventional coolant. It is non-toxic and biodegradable. The RMI-25 cooling system treatment helps your engine run cooler and stay clean. Water cools better than glycol coolant in typical Australian conditions. Because even thin scale blocks heat transfer, engines overheat over time. RMI-25 removes that scale and lowers coolant temperature by 7°C or more. It does more than cool. It cleans scale, rust and sludge from the radiator, block and heater core. In addition, it lubricates water-pump seals and valves. As a result, hoses and seals last longer and pumps fail less often. The RMI-25 cooling system treatment also protects the metal in your system. It guards cast iron, aluminium and copper against corrosion and electrolysis. It also prevents cavitation pitting in pumps and liners. Runs engines cooler, even under load Cleans scale, rust and sludge Stops corrosion, electrolysis and cavitation Lubricates seals and doubles hose life Non-toxic, biodegradable and low cost You can use it with straight water or with conventional coolant. Choose the RMI-25 cooling system treatment to cool and protect your engine. Engine overheating? Overheating happens when your radiator, block or cylinder heads can’t shed heat properly — often from scale, rust or poor heat transfer. RMI-25 will cool it by 7°C — or more Water cools more efficiently than glycol coolants, which aren’t necessary in typical Australian conditions. (Waterless coolants are essentially pure glycol, and your engine runs hotter.) Even a thin layer of mineral scale in the radiator and water jackets reduces heat transfer and raises temperature. That causes hot spots, inefficient cooling and, in severe cases, engine failure. RMI-25 lowers water’s surface tension for better heat dissipation and thermal conductivity. The result is noticeably cooler coolant temperatures, especially on hot days, when towing, or under heavy load. Proven results in harsh conditions Toyota Landcruiser fleet: Over 100 vehicles in harsh, hard-water conditions suffered about 25 water-pump failures a year from worn seals and cavitation. After switching to RMI-25: Year 1, only 1 failure; Year 2, zero. It protects against cavitation erosion and extends water-pump seal life, cutting costly downtime. RMI-25 cleans, lubricates and protects the whole cooling system. Instead of replacing expensive coolant, add it to your system and let it work as you drive. It improves cooling efficiency, reduces overheating and extends engine life. Simple to use One easy application — pour the required amount into your radiator, top up if needed, and drive. Non-toxic system cleaner Corrosion protection for all metals Inhibits electrolysis and rust Prevents water-pump failures Doubles hose and seal life Protects against cylinder pitting and cavitation Fluorescent leak detection for easy testing Cost-effective alternative to glycol coolant If antifreeze isn’t required, run straight water with RMI-25. For best results use distilled water to minimise scale. For remote travel, the cooling system can even serve as an emergency water source (only once all glycol is fully flushed). Savings history Water-pump failures costing $300–$4,000 Major engine damage and rebuilds from $4,000 to over $200,000 RMI-25 coolant additive Many cooling-system products fail to stop scale, corrosion or sludge. RMI-25 works differently: it breaks scale, rust and solids into microscopic particles and keeps them suspended, which may temporarily discolour the fluid. Within 6–10 hours you may notice a colour change. When you do: drain, flush, refill and re-dose. Repeat until the fluid stays clean — that shows the system is restored. RMI-25 works with conventional coolant and antifreeze, glycol-based systems, or straight/distilled water. It cleans the whole system, including the heater core, radiator, hoses and internal passages. Complete system protection Prevents corrosion, rust and scale Stops cavitation erosion in pumps and liners Protects against cylinder pitting Lubricates seals, valves and fittings Extends hose, seal and component life RMI-25 is non-toxic, biodegradable and safe for use in environmentally sensitive areas. Unlike products that mask problems, it actively cleans, protects and improves cooling across the whole system — from everyday cars to heavy-duty machinery.
