Cooling System Stop Leak - 325ml

Stops small leaks in the radiator and cooling system, with anti-corrosive properties.

• Stops and prevents leakages in the radiator, cooling and heating system.
• Stops head gasket leaks.
• Will not harm rubber hoses, gaskets or other system components.
• Is compatible with all antifreezes and coolants, also with OAT coolants (Organic Acid Technology).

How to Use:

1. Add to the cooling system.
2. One bottle treats up to 12 liters of coolant.

If the cooling system is excessively fouled, it is recommended to clean first with Wynn’s Cooling System Flush. Check coolant level. Start engine, bring to operating temperature with all heater controls in HOT position. Shake the bottle well and pour the total contents into the cooling system via the radiator filler cap or via the expansion tank in case of a completely closed radiator with through-flow system. Close the system and let the engine run for approx. 10 min. until the leak or leaks are sealed. If necessary top up with cooling liquid.
