Radiator sealant is a good option for a fast fix for a leaky radiator, gasket or hose. Radiator sealant is a chemical that when applied to the walls of a radiator will form a coating over any small holes or "pin pricks," keeping the radiator from leaking and allowing your vehicle to run long enough to get to a proper repair shop. Learning how to use radiator sealant is not difficult and is in fact an essential skill if you are concerned about one day being stranded along the highway with a cracked radiator.
- Purchase radiator sealant - Radiator sealant is available from a variety of automotive product companies. One time tested formula is that of Stop Leak. Stop Leak is one of the most widely recognized methods for helping to alleviate a leaking radiator.
- Pour the product into the radiator - Pour the recommended amount (normally one full bottle) of the product into the radiator. Unscrew the radiator cap and pour it in without draining any coolant out.
- Add radiator fluid - Add radiator fluid via the radiator cap until the level of coolant is equal to the amount recommended by the manufacturer.
- Start the Car - Start the car and allow the engine to warm up. This will circulate the plastic sealant through your cracked radiator and help to plug any small pinholes as well. Run the car for approximately 5 to 10 minutes to thoroughly coat the radiator.
- Fill the radiator - Fill the radiator with a 50/50 mixture of water and coolant to top off the cooling system.
- Allow the car to sit overnight - Allow the car to sit at least 12 hours so that the radiator sealant can set up properly. Then you ca drive as normal.
As with any process or repair technique, there are problems that can be radiator sealant problems. There are a few considerations to make when determining whether or not to use radiator sealant. In a pinch or an emergency situation, radiator sealant does exactly as it is supposed to do: stops the leaks. Radiator sealant is not a permanent fix as the plastic sealant will eventually wear out and the leak will return. However, if you are stranded alongside the road or need to drive the vehicle to a repair shop, utilizing radiator sealant is one of the best ways to avoid damage to your engine components and save money on a tow bill.
Radiator sealant is a great option for stopping a leaking radiator or radiator hose. It is not a permanent fix and should not be considered a long term viability option in lieu of having your radiator repaired or replaced. Products such as "Stop Leak" are easily administered to your coolant system and can save the day in the unfortunate event that your vehicle breaks down along the side of the highway and you have no means of getting help. Always having a bottle in the trunk of your car in case of emergency is a great way to avoid having to walk home!
