My car does not have a cap on the top of the radiator as the coolant gets added through the overflow. How would I add this to my car?

Thank you for your question, and for considering Bar's Leaks to help with a cooling system leak. The product you are asking about - Bar's Leaks Heavy Duty Radiator Stop Leak (part number PLT11) - is designed to be installed directly into the radiator. If you don't have access to the radiator through a radiator cap, you can remove the top hose where it attaches to the radiator and install the product in through the hose. Be sure to shake the product well before installing. If installing this way is not an option for you, we would suggest you consider our Radiator Stop Leak Tablets (part number HDC) instead. These pellets can be crumbled up and installed in the overflow reservoir, as long as it is pressurized. Please note: Cooling systems that are dirty or partially clogged should be flushed before using any cooling system stop leak products. If you have any other questions or would like additional information, please feel free to call our Tech Support team at 1-800-345-6572. We are here to assist you Monday through Friday, from 8 am to 5 pm, Eastern time.

Would this work in a polaris 4-wheeler?

This may work on any vehicle that the cooling system is not pressurized. Meaning that if your Polaris's cooling system is one of those pressurized cooling system this might not work. Might not, meaning may work as well. Good luck

What are the beads inside for? Can they be poured into the radiator?

The beads break down in the system and contain most of whats in the product to seal . ..... So yes, please pour the entire container into the vehicle. Great question... Thank you Eric
