  • How long does it take to see results?

    We recommend you drive/idle the vehicle for 15 minutes. In most cases the leak will be sealed instantly, but others will require up to 20 minutes. If the leak is not sealed in 20 minutes, a second application may be required or mechanical repair may be needed.

    No, Rislone® Cooling System Repair product is part of the next generation stop leak line which is certified to be used in all cooling system types. Safely and easily seal leaks in plastic, aluminum and metal (copper / steel) radiators, heater cores, gaskets and freeze plugs.

    Note: If using Rislone® to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core and is only opened in the HOT position.

  • What are the dosage recommendations?

    Use 1 (one) bottle for regular size cooling systems, this covers most 4, 6, 8 and 10 cylinder engines. For larger systems, use 1 (one) bottle for every 15 Liters of cooling system capacity.

  • How does Xtreme Cool™ make the vehicle run cooler?

    The Xtreme Cool™ additive in Cooling System Repair reduces the surface tension of coolant increasing the wetting ability. This improves heat transfer reducing coolant temperature helping to prevent overheating and leaks.
