Frequently Asked Questions

Can Rislone Radiator Stop Leak be installed in existing antifreeze coolant?
Yes, it works with all types and colours of antifreeze coolant and/or water.

Will Rislone Radiator Stop Leak work in the new extended life antifreeze?
Yes, Rislone Radiator Stop Leak works with all types and colours of antifreeze coolant and/or water.

Do I need to drain my cooling system after using Rislone Radiator Stop Leak?
No, this product is designed to be left in the cooling system to protect from future leaks and overheating.

How long does it take to see results?
We recommend you drive/idle the vehicle for 15 to 30 minutes. In most cases the leak will be sealed instantly, but others will require up to 30 minutes. If the leak is not sealed in 30 minutes, a second application may be required, or mechanical repair may be needed.

Will Rislone Radiator Stop Leak plug my heater core?
No, Rislone® Radiator Stop Leak will not clog a clean heater core. If using it 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?
Passenger cars and light trucks—Use one bottle for 6 & 8 cylinders and half bottle for 4 cylinder engines. Small engines or other small systems use approximately 20 mL per liter of fluid capacity. Over the road and heavy-duty equipment—Install one bottle for every 15 liters of coolant capacity.

Can I install Rislone in my overflow reservoir?
Yes, if direct access to the radiator cap is not available, install in overflow tank.

I accidently added the Rislone Radiator Stop Leak into my engine oil, what should I do?
It is only designed to be added to the cooling system. If the product is installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover and drain the oil leaving the drain plug off. Then use an engine flush washing out the head keeping special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, you need to take the vehicle to have a professional mechanic evaluate what can be done to clean the inside of the engine. This might include taking the engine apart to clean all of the parts.

Great buy
Size: 2 Count (Pack of 1), Style: Pack of 2
Easy to track balls. My dog loves them and I like that they whistle when you throw them cause some times my dog loses track of it in the air. This helps because they can hear where it's going. Will buy again.

My Dog's Favorite Balls
Size: 2 Count (Pack of 1), Style: Pack of 2
My dogs love these balls and won't play with any others. My lab has to carry the orange ball and track and retrieve the blue one. We have a system!

Our perfect chew toy for a relentless chewer!
Size: 2 Count (Pack of 1), Style: Pack of 2
We have looked high and low for a ball that our Australian Shepherd couldn't destroy. Read on to find out why we are sticking with this one. We've used other Chuckit! products in the past to mixed degrees of success. We absolutely love the ring fetch toy, though the dog can destroy those rings in a couple days. We tried other "nearly indestructible" balls only to have to throw them away within a couple days because our dog had destroyed them and left small pieces around the house for the baby to find. We have been COMPLETELY satisfied by these balls. They fit with the Chuckit! stick, which is a great bonus, but the most important thing is the dog hasn't been able to get pieces torn out of them. His orange one is his "indoor toy" and he's been going to town on it for weeks without any indication of wear. We periodically inspect it and are always floored to see that it's generally in the same condition as when we gave it to him. The orange color did fade a little when he left it outside for a few days in the sun, but considering how well it works otherwise, this didn't concern us at all. The "whistling" aspect of this ball is... well, an interesting gimmick but I wouldn't buy it if that's what you're interested in. Sometimes it makes noise in flight, other times it doesn't. We don't care. He chews it until he's tired of it (which is usually hours) and it squeaks and squorks on his teeth which keeps him happy as a clam. We honestly didn't think we'd find a ball that could keep up with his chewing, but this one has been phenomenal. We cannot recommend it enough!

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.
