Seal'Hints

In continuous production since 1933, updated periodically to meet modern automobile requirements and processed in a special way to enhance the features of the natural organic fibers to act like a clotting agent for your cooling system fluid.
.
It is an environment friendly, safe to use, undo'able, non-destructive, 100% Australian organic sealant.
Designed to stop leaks in the radiator, cylinder head and other areas of a water based cooling system.
A water soluble organic powder that will not cause harm to any components of your 
cooling system and is compatible will all water based automotive glycol coolants.

Depending upon leak, usually "cap full" to1/3rd of the vial will suit most needs and seals within several minutes.
The engine must be kept running and water levels watched for the sealant to work efficiently.
.
Super Seal provides a temporary repair until more effective repairs can be done.
Our sealant has a long shelf life and is reversible, so you can "un-do" the sealing action *
It is also very effective on gasket weeping & those similar type problems.
.
Also this product can save you money in keeping you on the road and again 
at repair time by not needing to replace clogged components.
Since 1933 our customers have been and still are amazed by it...

How long does it last?
In storage:  Super Seal will keep for years in its vial when stored in a dry place.   e.g. boot, glove compartment or tool box.
Using: For gasket weeps Super Seal can last months, generally between vehicle services. Over the decades customers have inform us they have left Super Seal in for years and it has kept the hole(s) plugged. Young's does not recommend reliance on the sealant for such long times but acknowledges these satisfied results from our customers.
.
How does it work?
When you apply Super Seal powder to your cooling system fluid, Super Seal floats on top at first, then in a few seconds most of the powder sinks into the cooling system fluid. The blended organic material is now saturated and flows around with the fluid waiting for exposure to external hot dry air. When exposed, the material starts clotting forming a plug on the hot surfaces around the hole and building upon itself until the breach is sealed. Internal clotting is arrested as the sealant is kept moist and pliable by the cooling system fluid. Super Seal can take seconds to several minutes to stop the smallest of weeps to fist size or bigger holes in radiator cores.  It is only a matter of time, enough sealant and water for Super Seal to do its job. For best results use in a well maintained vehicle and only apply Super Seal when needed. Super Seal is compatible will all glycol / water based coolants...
For greater efficiency switch off the cabin heater while patching holes, move the hot / cold slider lever on your dash board to the blue (cold) setting.
.
What's in it?
Without giving the trade secret away it is made from a blend of natural organic fibers. Super Seal is a fine dry multi-tone brown powder with a mild organic odour. Processed a special way to enhance features of the organic fibers and enable them to react as a sealant in water. Unlike other sealants it is safe to handle, if released onto the road will not affect the environment and starts working to plug the leaks within in a few moments... (engine must be running, water levels checked)... 
.
Other sealants
.
.
Some competitor products on the market can harm your cooling system or you!
e.g. Permanently block radiator tubes, clog thermostat, gum up the water pump or increase the corrosion factor of the cooling fluid. They stop leaks all right and the next day when you start your vehicle, the motor overheats very quickly and stalls or shuts down...
Quick fix 
.
.
.
These sealants tend to assume a "get you home / to safety" by the end of the drive, where you'll get the leaks fixed the next day; but in reality you are rarely able to get things fixed the next day and weeks may go by, so its a good idea to get a sealant that won't do damage to system components or need an aggressive dissolving agent or even worse, parts replacement (thermostat, water pump...) at repair time.
Slow fix 
.
.
.
These sealants can not stop the leak right now, you need to follow a procedure and use several products to 
stop the leak. These are usually kinder to system components but you need time and resources handy... 
So for "on the road" problems where most leaks are discovered / occur it is not very practicable, but these products are the most commonly found at service / refueling stations, where you can purchase the resources (parts, coolant, cleaners) which force you to make the time to allow the sealant process to work...
Harm 
.
.
.
.
Take a closer look at the labels of the "Quick fix" and "Slow fix" type sealants you may see,
WARNING or CAUTION messages with safety or first aid information... why?
This is in case their stuff gets on you or children drink/eat the product. Instructions like wash immediately, induce vomiting, call a doctor, seek immediate medical advice, you wonder what are they selling you, why is it so toxic and do you really want to be using their stuff in your vehicle or keep a bottle handy for future holes!

Young's sealant, has NO hazards and it is a "quick fix" sealant, but without the problems a chemical quick fix product.
Super Seal is the best, simple, safe to use, true to label and it works with a 70+ year proven track record. There are no warnings, no cautions and no need for first aid information as Super Seal is organic, you could eat Super Seal, but we don't recommend you do that.

* At repair time, the repairer simply flushes the cooling system, knocks away the dry sealant from the hole or around the leaking part of the gasket and then repairs the hole or replaces the faulty gasket. Recharges your cooling system with an appropriate coolant as per your automobile's handbook and your back on the road... Hopefully with a fresh vial of Super Seal handy if another cooling system leak ever happens...

Super Seal is not everywhere: If Super Seal is so good and been around for so long, why isn't it everywhere?
Slick marketing is one reason, competitors advertise their product aggressively and provide a type of "kick back" for places that only push their product on to customers. Young's has always declined to engage in this corrupt behavior, customers should be treated as good friends and be allowed to choose or advised what products will best solve their particular problem... (Competitors have been known to exchange 2 or more of their products for every Young's product to get us out of the stores market place. What does that say about how good our product is...)

Another reason is Super Seal is to good, a little bit goes a long way, has a long shelf life and does not damage other components. Which means there are no associated sales of replacement parts, the seller can't make as much and one vial can last years, so any ongoing sales may be slow. Stores that carry Super Seal show that they care about their customer and are happy to sell a product that saves you, the customer money...

Also some of the auto chains conditions of supply are in Young's view, impracticable and in the long term, unsustainable. 
Reluctantly Young's can not supply those chains, however, you will see selective stores exercising their consumer right to purchase goods from manufactures outside their respective auto chains list of approved suppliers... Young's understands more stores would like to buy direct but are afraid of breaching their respective franchise agreements... As for the idea 
of selling what the customers wants, its appears now days it is what the franchises can push...

How to Use Super Seal
YOU'LL NEED: A rag & clean water. 
DANGER: Potential steam burn - take care - Cooling system fluid may be hot.

1. Turn off cabin heater (for efficiency, unless leak is in cabin heater)
2. Use a dry cloth or rag to open your radiator cap.
   Check coolant level and top up if necessary with clean water or coolant.
3. Run engine to normal operating temperature (with cap on or off if stationary)

4. If your cooling system fluid is clean, usually green or red.
    Pour a cap full to 1/3 of the vial into the radiator.
5. Keep engine running until leak stops (typically 5 - 15 minutes).
    Keep an eye on the vehicles engine temperature indicator for over heating.
    Check the hole(s) and water level again. 
    If the leak is still weeping badly add another cap full to a third and add "clean"
    water if the level is down. If overheating engine STOP, see "how to undo".

   4 & 6 cylinder vehicles use cap full to one third at a time, maximum 1 vial.
   8 cylinder vehicles, trucks, tractors or any engine with  a large water / 
   glycol based cooling system capacity:
   Start with one third and add no more than two vials.

6. After 30 minutes cabin heater may be used.
   Have your vehicle serviced as soon as practicable.
   Refill cooling system with correct percentage of coolant, typically 50% if you've
   only added water to the system. (you may have diluted the coolant to much).

If radiator has NO cap - it is probably a closed coolant system.
These have an overflow / flow through bottle, add above to this bottle.

IF IN DOUBT on doing any of the above call in an expert!

special treatment or tools which is beyond the ability of Young's to foretell.

How to Undo (remove)
YOU'LL NEED: A rag & clean water.
DANGER: Potential steam burn - take care - Cooling system fluid may be hot.

Opps to much at patch time:
1. Follow step 1 & 3b below.
2. If you feel you've flushed the system enough, 
    Refill with clean water and try again.

Usually done by a qualified repairer...
At repair time:
1. Discard the coolant, thoughtfully (NOT into water ways or storm water drains)
    coolant can de-oxygenate the water, sewage system may be acceptable 
    check with your local authority.

2. Identify all holes for repair.
   e.g. Mark with texta, liquid paper etc.

3. Reverse flush the cooling system with water.
a.  Use a hose to force water in top radiator hose in reverse flow direction or
b.  Refill by gravity with water into radiator top tank & circulate / drain through.

4. Fix the hole(s). (solder, weld, replace gaskets etc.)
   Any sealant clumps at holes can be tapped out of the way or soaked off.
   Any missed sealant burnt by the soldering process may smoke but will not
   cause harm to repairer.

5. Refill with fresh coolant as per vehicle handbook.
   Typically in post 1986 vehicles its 50% coolant 50% water.
