Don’t Throw That Old Floor Jack Away!

Can Bar’s Leaks products save you money? If by ‘saving money’ you mean preventing your spouse from throwing away a perfectly repairable floor jack, yes!

We received the following letter (plus receipt and product label) from Jeannine L. from Bronson, TX. Long story short: her husband threw away an older hydraulic floor jack because it would work properly any more. Jeannine, after researching Bar’s Leaks products on YouTube, used Bar’s Leaks Jack Oil with Stop Leak on their bigger floor jack and repaired it perfectly. Hydraulics restored, full function, all leaks stopped – and this one didn’t get thrown away!

Thanks Jeannine for taking the time to write us. Glad we could help save your floor jack’s life.

Will Bar’s Leaks Head Gasket Products Fix Your Head Gasket Leak?

By far the number one question we get on our tech lines and Facebook is:

“How can I tell if your head gasket products will fix my head gasket leak? I’ve heard some of these products don’t work.”

First off, if you haven’t read our Buyer’s Guide on choosing the right head gasket repair solution, you might find that helpful when it comes to deciding which of our products is best suited for you, your technical expertise level and your particular problem.

There is one ultimate truth, no matter what any chemical tool vendor tells you: if your head gasket leak is too serious, no chemical tool will seal the leak. None. Zip. Zero. We’d love to tell you otherwise, but we’d be lying. If your leak is severe, then you’re looking at a physical repair. That’s the reality. It’s a bummer, we know.

But there are many shades of gray between a perfectly healthy head gasket and one that needs a physical repair, and that’s where we come in.

So, here’s how to tell if your head gasket leak is a candidate for one of our head gasket repair solutions:

HG-1 PNG old     1100 PNG     1111 PNG

Can your car run or be driven for 15 minutes without overheating?

First, the bad news: if your vehicle cannot run for 15 mintues without overheating, your leak is probably too severe to be chemically sealed. In cases like this, there is less than a 50% chance we can help.

But if your vehicle can run for 15 minutes without overheating, then our strongest product, Bar’s Leaks Professional Head Seal Blown Head Gasket Repair (p/n HG-1) will likely work. HG-1 is our most expensive product, one that’s truly pro-grade, but it’s also our strongest formula, designed for the toughest leaks. It’s also very convenient and easy to install, with no draining or flushing necessary unless the cooling system is dirty or partially clogged or if you need to drain some coolant out to get the proper dosage in.

But wait. Before you decide on our HG-1 product, there is another question:

Can your car run or be driven for 20 minutes without overheating?

If so, then you are likely a candidate for our Bar’s Leaks Head Gasket Fix (p/n 1111), one of our most wildly popular products. Why is it popular? It has a medium price point and is very easy to install because it’s antifreeze-compatible.  Its sealing strength is a bit below our HG-1 product, but the installation is quick and easy. For most mild to moderate HG leaks, this product has worked wonders for tens of thousands of customers.

If you want a cheaper, but also strong product whose installation is a bit more involved, our Bar’s Leaks Head Gasket Repair (p/n 1100) is a great option. It offers a very strong seal, (though not as strong as our HG-1) lower price, but installation is more demanding because the formula is not compatible with antifreeze.

So, in a nutshell, this is how you can tell if one of our products will be able to help with with your head gasket leak:

  • If your vehicle can run for 15 minutes without overheating and you need our most professional-grade solution, consider our HG-1 product.
  • If your vehicle can run for 20 minutes without overheating, consider our 1111 product or 1100 product, depending on how easy you want the installation to be.
  • Bottom line that most chemical seal vendors won’t tell you: If your vehicle overheats within 15 minutes, chances are you need a physical repair by a licensed facility/mechanic. We’d love to be able to sell you a product, but if your car is overheating rapidly, no chemical fix will work. It’s not just ours that probably won’t work, but any. Save your money for a mechanic’s attention.

Buyer’s Guide: Preparing Your Car For Colder Temperatures (Especially Your Radiator)

By far the number one question we get this time of year is, “What can I do to prepare my car for winter?” We know other companies run promotions around this, but the purpose of this article isn’t to advertise to you. It’s to help you prepare your car for cooler weather based on the decades of data we have about what goes wrong when temperatures drop.

There are three main things you need to do to winterize your car. These things serve as a very effective insurance policy against breakdowns, overheating and other temperature-related car problems.

  1. Full radiator flush — help clean and prepare your radiator for cold weather. Your radiator is the heart of your car during fall and winter. Because of this, it’s good to remember the old cliché: an ounce of prevention is worth a pound of cure.
  2. Pay attention to your water pump — before temperatures get too ugly, take a step to protect this critical part and prevent the formation of rust and corrosion.
  3. Take a proactive measure against leaks in your radiator. The worst time to find out you have a major leak is on your drive into work on a bitter winter morning, so take a simple step to nip leaks before they start.


We recommend you begin with our Bar’s Leaks Radiator 10 Minute Flush (p/n 1211), which is a simple and very affordable way to ensure your radiator is clean and in top condition. It’s compatible with all automotive cooling systems. It’s safe to use on aluminum and plastic radiators. And it is best used when performing a normal cooling system service, like an antifreeze flush and fill (which is another good idea before the cold weather starts).



1311 PNGBar’s Leaks Cooling System Water Pump Lube with Anti-Rust (p/n 1311). This product protects aluminum, copper, iron and all other parts of the cooling system to help prevent the formation of rust and corrosion. In addition, the water-soluble oil formula lubricates the thermostat and the water pump seal, giving you broad protection against failure. It also lubricates the thermostat, another important (and often overlooked) part of your cooling system.

Not many people think about their water pump as part of a winterization schedule — until it’s too late.

If you have even the smallest leak in your radiator, now’s the time to squash it. Our Bar’s Leaks Cooling System Repair (p/n 1150) is not only designed to stop any leaks you might have, but also condition and protect your system against future breakdowns. In our experience, for many vehicles this is your last chance before paying an expensive repair bill or replacing the vehicle.



Don’t ignore one of our most popular winter products to help keep your snow plow in top condition: our Bar’s Leaks Jack Oil with Stop Leak (p/n HJ12). Compatible with all snow plow fluids, this formula helps prevent leaks and

Your plow is a money-maker during the winter months. Don’t find yourself missing billable days because your plow is inoperable. Take one simple, affordable step to make sure your plow is reliable as you need it to be when the snow starts falling.

If you have any questions about any of these products and how to use them, please email our support team or hit us up on Facebook. We’re always happy to help.

Thanks for reading. Hopefully, you and your car enter the colder months knowing you have a few good insurance measures against winter breakdowns in place.


When an Oil Leak Gets Ugly: The Oil-Soaked Starter

One of the symptoms of a oil leak that almost nobody talks about is when oil saturates and damages a starter. This equals a (sometimes expensive) repair, and if left unchecked the leak can go on to cause other issues. Bad news all around. We know. We talk to tech line callers about it frequently.

Typically, when you notice an oil-covered starter, the oil leak is coming from the engine’s rear main seal, which unfortunately is common, especially in older cars. With today’s attention on keeping cars longer, it pays to take care of oil leaks before they rack up repair bills. What starts with a small oil drop on the driveway here and there can quickly escalate into a damaged starter and other problems.

Most haven’t seen what an oil-soaked starter looks like, so we’ve taken some pics in our lab to show exactly how an oil leak can spread and damage the starter:


Not a good problem to have. Rear main seal leaks can start at 60,000 to 80,000 miles. Many people won’t notice a rear main leak for a while as it is gradual. The oil leaks, gets covered with dirt and road grime, then more oil builds up on top of it, which is what this starter picture represents.

It’s a slow process that can one day present problems you never knew you had.

When we talk to customers on our tech lines, we tell them to use Bar’s Leaks Concentrated Rear Main Seal Repair (p/n 1040) for engine oil leaks. The formula is tried-and-true, with over 2.2 million bottles sold across the USA. It seals rear main, cam seal and timing cover leaks, and restores shrunk and hardened seals.


Most importantly, it’s safe and easy to use, even if you don’t know much about engines. In under three minutes, you can have Bar’s Leaks Rear Main Seal installed and working in your engine to stop your oil leak. We engineer our products to be safe and effective, no matter what. Guaranteed.

Bar’s Leaks Block Seal: “Rarely does any product work as intended, but yours absolutely does!”

Richard from Black Canyon City, AZ, just sent us this awesome testimonial about our Bar’s Leaks Liquid Copper Block Seal Intake & Radiator Stop Leak (part 1109). This is what he writes: 1109 PNG

Last year I bought a ’96 Mustang GT, knowing at the time the head gasket was going out soon (180k at the time I bought it and a noticeable “loss” of coolant each week).

As-is, the car ran OK for about 6-months, but I still hadn’t found the time to get the repair done. Last month it overheated twice on my commute to work, so I picked up a bottle of your Liquid Copper and decided to try it (trying to buy a little more time before I had to overhaul the engine). To my surprise (I’ve tried other products on vehicles in the past, each one doing more damage than good) your product immediately smoothed out the idle and eliminated the coolant loss! The leak is between the #2 and #3 cylinders (these fouled out minutes after changing the plugs) and I was losing about 2 gallons a day prior to treating my car with your product!!

You’ve got a customer for life because the product actually worked as suggested! Rarely does any product work as intended, but yours absolutely does! I want to thank you guys for creating such a great product! Because your product has worked beyond my own expectations, I’ve got time to save and prepare for a proper overhaul on my Mustang!

Richard, thanks a million for taking the time to tell us about your experience. The #1 issue we combat every day is to prove our solutions are a cut above everything else out there, because as you write, not all are created equal.

Thanks again, and send a picture of your Mustang along and we’ll get it posted!
