How to Repair a Radiator Leak

While none of us want to suffer from a radiator leak (they suck, trust us, because we hear all the horror stories from customers), it’s important to know the signs and take action to avoid a major coolant leak before it happens.

At the first sign of coolant leaking from your radiator, you should avoid driving your vehicle and take steps to stop the leak. As experts with over 70 years of experience in vehicle fluid system repair and treatment, our engineering and technical support teams want to point out the signs of a radiator leak and give you tips on how to repair it.

How Long Do Stop Leak Products Last?

At Bar’s Leaks, we like to think of our engine stop leak products as temporary fixes that last forever! Kidding aside, in some cases, the only way to repair a leak is by replacing the faulty part. Certain head gasket, oil pump, radiator and power steering line leaks are simply too severe to fix with ANY chemical repair tool. In many other cases, when you first detect a leak, you can save a lot of money and get a long-lasting fix with one of our advanced formulations.

So how long can you expect them to last? It depends. If the leak is mild to moderate, we’ve had customers run 10,000-50,000 miles with no further issues. If the leak is more severe, or on the edge…

How Does Radiator Stop Leak Work?

We like to write about our radiator stop leak products a lot on this blog (we are known for cooling system repair solutions, after all!), but some of you might want to know exactly how they work! Thanks to a time-tested and proven chemical formulation, our radiator stop leak products make quick work of stopping minor-to-moderate radiator leaks for good.

Unlike products from years ago that simply gummed-up holes as a temporary fix (and often gummed up coolant passages and heater cores at the same time!), our radiator stop leak won’t cause any degradation in the flow or performance of your radiator. We always instruct customers to install our products into a clean cooling system, which sometimes means a flush will be useful. Why? Installing…

The Basics of Cooling System Maintenance

We don’t often think about our cooling systems. We fire up our vehicles and drive to where we need to go. On top of regular checks of your engine oil, tires and brakes, it’s a good idea to add your cooling system to your vehicle maintenance checklist. A clean and efficient cooling system not only helps extend the life of your vehicle, but it can also help avoid costly overheating or breakdown issues that occur due to cooling system negligence. The #1 reason we hear about that get people stuck on the side of the road is – you guessed it – cooling system problems. Let’s give some attention where it’s due.

Things You Should Know to Protect Your Radiator

You probably know this, but we’ll say it anyway: the radiator at the front of your vehicle is probably THE  key component in your cooling system. As hot engine coolant is pumped through, your radiator uses exterior air (either while you’re driving or from a fan) to cool the coolant so that it can be pumped back into the engine and remove more heat. This hot/cold cycle continues as long as your engine is running.

Understanding how your radiator works can help you find ways to protect it. From physical damage to internal debris and corrosion, there are many factors that can degrade the performance of your radiator or even cause a leak. We’ve put together this list of ways you can protect your radiator…
