## Overview

Bar's Leaks 1100 Head Gasket Repair is a 20 oz. dual-action sealant combining liquid ceramic and reinforced fibers to permanently seal blown head gaskets and cracked cylinder heads. Designed for cast iron and aluminum engines, it forms a heat-resistant, ultra-strong ceramic seal that prevents coolant leaks and engine overheating. Ideal for vehicles that can idle without overheating, this product offers a cost-effective alternative to expensive repairs, backed by clear instructions and proven user success.

## Description

For most vehicles, this is the last chance before going to a junk yard or paying an expensive repair bill. This product contains a blend of aramid and refractory fibers giving the strength of a bullet proof vest and the heat resistance of fire-proof clothing. As these particles penetrate a crack or the blown head gasket area, they lock together and bond forming a hard permanent ceramic type seal. Your vehicle is a good candidate for this product if it can idle for 20 minutes without overheating or having to add coolant. Works effectively on cast iron or aluminum blocks & heads. Detailed instructions on back booklet label take you through each step of using the product.

Review: Really pleased with how well this works - I have a 3 cylinder, diesel, 19 horsepower landscape tractor that blew a head gasket (or head, or block, don't know) and was getting exhaust gasses into the radiator water. This caused over pressure and would blow all the coolant out of the radiator in just a few minutes. Since I've taken off diesel heads before and found them to be cracked or a crack in the block, I didn't want to go that route as a first effort. I want to use the tractor before winter comes darn it. I ordered this from desertcart, and followed the directions to the letter. Since I didn't have a spark plug to remove (remember, it's a diesel), I opened the compression release for each cylinder until I found out which one was giving me trouble and left that one open during the first part of the process. Net, this stuff worked. While the tractor was running I held the end of the overflow hose in a jar of water and watched the bubbles come out. In a few minutes there were less bubbles, a few minutes more, even less. I ran the tractor for a little longer than the instructions and then drained and refilled it. There were a few bubbles at first, as compared to a blast of compressed exhaust gasses when I started, and those went away after driving the tractor around the lot a little. It's only been a few weeks since I did this, so I don't know how long the fix will last. However, I got a bottle of the other Bar's product Block Seal 1109 and put half a bottle in the radiator to take care of any residual problem. Haven't had to add water at all and there are no bubbles in the overflow bottle. If you can't fix it right by replacing the proper parts, get this stuff; it actually does what it says it will.
Review: Does it work?yes - Fixed leak and is running 90% better

## Questions & Answers

**Q: How do I get it into my radiator that does not have a cap but only a reserve for the overflow**
A: This is a minor, although messy problem.  Simply disconnect the upper radiator hose to get access to the radiator fluids.  You'll probably need a funnel and maybe a little duct tape.  My neighbor used a gallon milk jug as the funnel and his hand to make sure the fluid got where it was supposed to be.  Also, if you drain it at any time, just take off the lower radiator hose.

**Q: should I remove the old coolant before using this product?**
A: Read the directions

**Q: this product can fix a crack in the engine block of a car?**
A: Although it is impossible to guarantee that it will work in every situation, it does quite often seal up block leaks......  It's most always worth a try, before you resort to rebuilding an engine.  Thank you  eric

**Q: Its actualy 2 question. Does this work with V8**
A: In my case it wont work

Scotty Kilmer used this stuff on his youtube channel. Worked for me too. I still made sure my radiator was clean as possible. If you have rust in your cooling system it will not work.
