About This Product
Why the Rislone Radiator 10 Minute?
Scale, rust, and deposits build up in the cooling system over years — they reduce heat transfer efficiency and can partially block cooling passages. Before adding fresh coolant, flushing the system of these deposits ensures the new coolant can work at full efficiency. The 10-Minute Flush is a fast, powerful cleaner — run it for 10 minutes at operating temperature, then drain and flush with water before adding fresh coolant.
How It Works
The 3-step process explained
1
Acid Action
Mild acid dissolves mineral scale and rust deposits from cooling passages and radiator cores.
2
Detergent Action
Removes oil contamination from the cooling system (often present after a head gasket leak).
3
Suspension
Dissolved deposits are suspended in the fluid and drain out with the flush.
How To Use
Step-by-step instructions
With engine cold, drain as much existing coolant as possible.
Fill the system with water and add the 355ml Flush.
Run the engine at operating temperature for 10 minutes with the heater on full hot.
Allow to cool, then drain completely.
Flush twice with clean water to remove all flush residue.
Refill with fresh coolant of the correct type and concentration.

How It Compares
vs other options
This is a pre-coolant change treatment — use it every time you change coolant. Do not leave the flush in the system after the 10 minutes — it is not a permanent coolant and will corrode metal surfaces if left.
FAQ
Common questions
Are Rislone additives safe for Indian vehicles?
Yes. Rislone is an American brand formulating automotive additives since 1921. Their products are designed to be compatible with all modern engine oils, coolants, and transmission fluids. They are sold in over 70 countries and are safe for Indian petrol and diesel engines.
Can I use a stop leak additive as a permanent fix?
Stop leak additives condition rubber seals to swell slightly and re-seat. They work on slow seeps and minor leaks and the effect can last 30,000-50,000km. They are not a replacement for a mechanical repair on a major leak — but for minor seeps, they are a legitimate and commonly used solution.
Will fuel additives void my car's warranty?
No — adding a fuel system cleaner to the tank is no different from using a different petrol pump. Indian car manufacturers do not prohibit fuel additives. If a dealer ever claims this, ask for the specific clause in the warranty document.
How often should I use a fuel system cleaner?
Once every 10,000-15,000km or approximately once a year for normal use. If you use a specific station known for poor quality fuel, every 5,000km is reasonable. The cost is ₹900-2,400 and it takes 30 seconds to add to the tank.
