La Niña Predicted to Bring Cold Snowy Winter: Get Ready for Spike in Cooling System Leaks

Every year, Bar’s Leaks®  is asked by the media to highlight four affordable solutions to repair cooling system leaks, which are more frequent during the cold months. Here are this year’s recommendations based on our experience.

Bar's Leaks Stock Up For Winter Products

Winter is hard on vehicle cooling systems, and weather predictors like AccuWeather are forecasting this year’s switch from El Niño to La Niña to bring bitter cold in the Northern Rockies and Northern Plains, persistent cold in New England and heavy snowfall in the Great Lakes region. This harsh weather will result in many vehicles – especially older vehicles – being unable to keep their engines at a constant operating temperature due to a variety of cooling system leaks. These cooling problems arise year after year, and we are asked by the automotive trade press about what we recommend as good first-option repairs.

“Just about when Daylight Savings Time ends and winter cold starts to kick in, auto parts stores and big retailers like Wal-Mart generally see a higher demand for Bar’s Leaks® cooling system repair products. Our products have been protecting and repairing vehicle cooling system leaks since 1947,” says Jim Moffitt, longtime VP for Bar’s Leaks. “Cold temperatures make leaks in the radiator, heating core, head gasket or freeze plug cry for attention. That’s why we encourage customers to be prepared and stock up to meet this seasonal demand.”

Here are four of Bar’s Leaks’ best-selling cooling system repair products that have served on the front line in cold, harsh weather conditions. They are all designed to be added directly to the cooling system without flushing the antifreeze, and are compatible with both conventional green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) antifreeze or water.

What Does a Blown Head Gasket Mean?

HG-1-Box-PNGIf a blown head gasket sounds bad to you, that’s because it is. A blown head gasket is one of the more troublesome and expensive engine problems you can face. Replacing a blown head gasket takes hours of work and high costs in parts and labor. Additionally, by the time your head gasket has blown, you might also have done other damage to your engine.

At Bar’s Leaks, we specialize in products that are proven to stop and repair cylinder head gasket leaks. With 69 years of experience, we are so confident in our products that we offer a lifetime guarantee on our HG-1 Blown Head Gasket Repair product. A blown head gasket may sound scary, but we have the solution!

What Happens

To understand exactly what having a blown head gasket means, you have to understand a little bit about how an internal combustion engine is designed. There are three major parts:

  • The block: This is the large base of your engine, bolted to the frame, and it’s where the pistons are. When in operation, the movement of the pistons creates a lot of friction, heat and stress, which requires cooling by way of engine coolant channels built into the block itself and oil.
  • The head: This is the top part of your engine, and it’s bolted to the block. It’s in the head that the actual combustion of the gas and air mixture occurs, which creates extreme heat and stress. The head will expand and contract at a different rate than your engine block, creating even more stresses.
  • The head gasket: This is the thin metallic gasket that is sandwiched between the block and the head. It is there to keep the coolant, oil and combusted gas sealed in their respective chambers and galleries. The massive thermal and mechanical stresses your engine exerts are very hard on the head gasket.

Even in normal operating conditions, the head gasket has to resist many different stresses, such as:

  • Pressure: Your coolant, oil and combustion circuits all exert pressure on the cylinder head gasket. While the head gasket is designed to withstand these pressures, over time, it can start to break down.
  • Thermal: The heat generated by your engine causes the block and head to expand and contract. The different rates of thermal expansion can work the head gasket in different directions.
  • Vibration: Years of vibration of your car and engine can create small cracks in the cylinder head gasket. While small cracks may not leak, over time, they get bigger and can result in a failed gasket.

Once these stresses have started damaging the head gasket, it’s only a matter of time before it starts to leak. At the earliest sign of a head gasket problem, consider using Bar’s Leak HG-1 Blown Head Gasket Repair. It’s our guaranteed solution for your mild to moderate cylinder head gasket leak. Find out how Bar’s Leaks has earned the reputation as a top-quality product you can count on for years. Get more life out of your engine and avoid costly cylinder head gasket repairs that can run into the thousands of dollars with Bar’s Leaks!

Subaru 2.5L Engines are Known for Cooling Problems

What You Need to Know About This Article

  • Subaru 2.5L engines have a mixed history of cooling, head gasket and oil leaks
  • There are specific ways to test a Subaru 2.5L engine for leaks, and not all testing methods provide reliable results.

  • There’s a difference between OEM and aftermarket parts for Subaru engines
  • Bar’s Leaks products have helped hundreds of thousands of Subaru owners insure against and solve cooling system, head gasket and oil leaks

Out on the open road, a vehicle’s engine can get mighty hot amidst the high speeds and sharp inclines of freeways and steep terrains. Under the hood of each car lies a series of complex components, some of which heat up in the process of powering the engine, and others that exist to counter these effects and prevent things from overheating. From the thermostat and fans to the radiator and coolant reservoir, each part relies on the other to keep the engine cool for safe driving.

What are Some Symptoms of a Blown Head Gasket?

HG-1-Box-PNGA blown head gasket is a major problem. It can starve your engine of the coolant it needs to keep from overheating, and it can allow your coolant and oil to mix. Once that happens, if you continue driving, your engine can suffer catastrophic failure, making it undriveable.

At that point, the only solution is an expensive engine rebuild or replacement. Thankfully, Bar’s Leaks exists to prevent that from happening. Our proven products are easy to use — and you don’t need to be a mechanic or car expert.

The most important thing to do is identify a problem with your head gasket before it becomes a major leak. Here are some of the most telltale symptoms something is not right with the head gasket:

  • Coolant loss: While coolant loss can come from different causes, a leak in the head gasket will result in a loss of coolant. This can be small at first, so it’s always a good idea to frequently check your coolant level.
  • Cloudy coolant in the tank: If you see a cloudy, milky appearance to the coolant in the reservoir, it means oil is getting in there. That’s another obvious sign of head gasket problems.
  • White smoke from your tailpipe: The presence of noticeable white smoke coming from your tailpipe is likely the result of coolant getting into your combustion chamber, again a sign of a head gasket leak.
  • Air bubbles in your radiator: With the radiator cap removed (always be careful, especially when hot!), you may be able to see signs of a cylinder head gasket leak with the presence of air bubbles.
  • Visible leaks: After driving your car, pop your hood and look for any leaks between the cylinder head and the block. Use a flashlight and small mirror to inspect the hard-to-reach areas.
  • Rough driving / hesitation: If you get to the point where your car is running rough, it means you already have some pretty serious head gasket damage. Time to react!

Once you’ve determined you have a blown head gasket, you have no time to waste. At the earliest moment possible, you’ll want to add our Bar’s Leaks HG-1 (Blown Head Gasket Repair) product. It is guaranteed to stop mild to moderate coolant leaks — and at the fraction of the price of a replaced cylinder head gasket. This is especially comforting for owners of older vehicles, where the cost of gasket replacement surpasses the cost of the vehicle itself.

Before your next drive, check your coolant level and the appearance of your coolant in the reservoir or radiator. Then watch for the various symptoms of a blown head gasket when you’re out on the road. At the first sign of a problem, you can always ask a mechanic to check out your engine and confirm your cylinder head gasket leak.

If you have a leak, a bottle of Bar’s Leak HG-1 is all it takes to get you back on the road. With almost 70 years in the business and proven technology in every bottle, Bar’s Leaks is the smart, easy and affordable solution to your blown head gasket. Now that you know the symptoms of a blown head gasket, you can detect one before it comes a problem and apply the guaranteed solution: Bar’s Leaks!
