A Guide To Radiator Stop Leak

Radiator stop leaks are products that can extend the time a person goes before they have to have their radiators replaced. Although they’re not designed to be a permanent solution to a leaking radiator, they often work well enough to keep a car going until it can be fixed. And for that purpose, they work well. However, that doesn’t mean that a person should just run out and buy the first stop-leak products they see. After all, there are some subtle differences between the different brands that are worth talking about. Weeding out the products that don’t work so well will help you find the best radiator stop leak for your automobile.

How To Find The Best Stop Leak For Radiators

Although there aren’t a whole lot of differences between most of the major stop leak brands, there are a few things to consider before buying them. As we stated earlier, not all of these products work as well as they should, so you should take a few moments to consider the following points before buying one of these products.

Product Compatibility

One of the first things you should do before buying a stop leak product is to make sure that it’s compatible with your vehicle. Although most consumers believe that all of these products are capable of being used in all vehicles, that’s not actually the case. As a precaution, always check and make sure the product can be used with your vehicle.

The Manufacturer Of The Product

It’s also a good idea to consider who manufactures the product before you put it in your car. That’s the advice we would give for any product added to the car. There’s a lot of great automotive stop-leak manufacturers that have earned the trust of the public. This includes brands such as J.B Weld, Bar’s Leaks, Prestone and AC Delco. If you don’t recognize the name of a particular automotive product brand, then you might want to consider a name brand.

Does It Require A Radiator Flush?

The next thing to think about is whether the product that you’re buying requires your entire radiator system to be flushed out before it can be used. There are some brands that require a complete radiator flush to be effective, and there are other brands that can be added right to the radiator without any further preparation.

Consider Leak Size

The last thing to think about before buying a stop leak product is whether or not the leak is small enough to be even controlled with this type of product. If the leak is too heavy, then you might have to just have the radiator replaced. If that’s the case, then buying a stop leak product will just be a waste of money, so be sure before you shop.

How To Use Stop Leak

Although the scope of this article is a bit too limited to get into every single detail surrounding the use of these products, we can give our readers a few tips on the general use of these products. The following steps might not apply to every single product, but it will apply to the majority of them.

Read The Directions

The first thing that should be done once you’ve bought the appropriate product for your car is to read the product’s directions. And that means all of the product’s directions. Once they’ve been thoroughly read, then follow those directions to the letter. If any of our following directions disagree with the directions on the stop leak product you’re using, then follow your product’s directions. That’s the only way to be sure that the product is going to work as it was designed to work.

Pour Product Into The Radiator

These instructions assume that you’re not using a radiator stop leak that requires the radiator to be completely flushed, but assumes that you’re using a pre-mix product. The first step is to remove the radiator cap and pour the recommended dose of stop leak into your car. When that’s been done, put the radiator cap back on. The second step is to start the car and allow it to idle for approximately 15-minutes, once the vehicle has been thoroughly warmed up. After the 20-minutes, give the vehicle several hours to cool off and then top off your radiator with a 50/50 mix of antifreeze and water. Once that’s done, allow the car to sit overnight before driving it any significant distance. When all of that is done, then the leak in your radiator should be adequately plugged by the product.
