If a leak is found in the system, then Coolant Seal could be the answer. Obviously, a sealer cannot repair a damaged or faulty part such as a broken fan or replace oil when levels are low, but if a leak is found then you cannot find a better sealant than Coolant Seal. Designed with strength in mind and ease of use, Coolant Seal can fix leaks in your head gasket, radiator, heater core, water pump or freeze plugs. If there’s a leak, but you can’t figure out where it’s coming from, you want to run a pressure test. Here are the steps to follow. So, what do you do if you have a cooling leak? Replace the leaking part – usually a hose. In an emergency one can bind up a hose dribble, and can ignore a minor leak from the radiator provided you keep topping the coolant up when the low coolant light comes on or there are signs of overheating. If the pressure drops but you don’t see a leak, assume that you may have a blown head gasket. 2. Fix The Leaking Part Either way, when the clamp wears out, the hose is going to leak. As with a leaking hose, you want to fix this problem sooner than later before the clamp gives out completely. 3. Leaking Water Pump

Simply living with the problem and topping up when necessary may solve the immediate problem for a while, but the underlying issue, if ignored could lead to much more serious damage as well as cause issues such as lower fuel economy, increased emissions and a general drop in engine performance. Reasons for Coolant Loss: In this guide, we cover the top reasons for a coolant leak. We also show you how to find it and fix it so you don’t cause more damage to the car. When you are all done, you’ll know more about the price to fix a coolant leak and find a few helpful answers to your top questions. Common Reasons For A Coolant Leak You have a slow coolant leak – a few drips on the drive, occasional overheating, heater running cold. Solution – add a sealant such as Radweld, K-Seal or Barr’s leaks. WRONG! These materials will more or less permanently damage the engine, radiator and heater matrix. We carried out some experiments on afflicted car. We flushed the engine in the conventional manners and then fitted a see-through coolant filter. Within a few moments of running the flushed engine the filter was clogged with old sealant. When this happens, the engine starts to overheat. If you leave it unrepaired, you could cause serious engine damage. 4. Leaking Intake Manifold GasketAfter a successful repair by Coolant Seal you can either flush the system or leave the product in the system. Any remaining Coolant Seal will not cause damage to the cooling system; however if the repair has been effective it is not necessary to leave it in the system as the repair will be permanent. What if I use Coolant Seal and it does not work?

Drain a few litres of coolant from the system. Shake Coolant Seal well and add to the system. Replace the coolant that was removed and continue with the treatment as per instructions. A garage can use a gas analyser to detect a head gasket leak. It tests for hydrocarbons (unburnt fuel) in the coolant system. If there is any present the gasket is blown. Be sure to take extra care that the engine is cool before application as opening the cooling system while the engine is hot or running may cause severe burns. Yes, coolant seal can be used with all common types of antifreeze. What are the symptoms that Coolant Seal can help with?

What causes the coolant level to drop?

Coolant Seal does not cause 'clogs' due to fibrous carbon fibre pieces which only settle where there is pressure near a leak in the coolant system, resulting in a layered effect which prevents clogging. Coolant Seal may react with other products which are in the coolant system, so flushing the system before use is recommended What should I do if I have tried another similar product before using Coolant Seal? There are many symptoms of cooling system damage, dependent on the exact nature and location of the damage. Coolant Seal can help with many of these symptoms, including:

Repairing leaks in the cooling system will also prevent against future head gasket failure by reducing the risk of overheating. Once solidified the material cannot be washed away or, as far as we know, dissolved in anything. It becomes a clay-like pudding which can only be scooped out by hand having removed the cylinder head(s). Physical force with a water hose can dislodge the heater matrix clogging, but if there’s any of the material left in the system it will simply clog up again. A small coolant leak may seem like it is a minor inconvenience. You simply top up your coolant and go on your way. Ignoring the signs is a dangerous game to play and the consequences of inaction could be result in a simple, inexpensive repair becoming a serious and expensive one. It is possible that Coolant Seal may react with other products or additives in the system. If you are unsure we recommend flushing the system before use. I have accidentally added Coolant Seal to the oil / fuel, what should I do?Fill the radiator with coolant. Take your time, as the level may drop as some air bubbles pop on their own. Once you have repaired the problem, you must refill the cooling system and bleed it. There should never be air inside the cooling system. Here are the steps to help you with this procedure. Coolant Seal can be used on any water-cooled engine regardless of fuel type (petrol or diesel). One bottle of Coolant Seal will treat up to a 4 litre engine but the product can be used on an engine of any size. Is coolant seal compatible with all types of antifreeze? Some of these issues aren’t a big deal and can be easily repaired, while others indicate a serious problem. Let’s take a closer look. 1. Leaking Radiator Hose

Coolant Seal can be used as a preventative against possible future leaks, however we cannot guarantee the effectiveness of the product over time.

Coolant leak: the difference between internal and external leaks

I will have to make a journey to the hospital today to have this ridiculous grin surgically removed from my face. Dealing with you and the rest of the KWE Team has been a pleasure. Many thanks. Mr D.J.W., Lanarkshire, KWE Suspension/Brakes/Steering For significantly smaller engines such as motorbikes or scooters use around half a bottle. Make sure to shake the bottle well to make sure product is mixed evenly. Where do I add the Coolant Seal? With a serious leak, no amount of sealant is going to fix it, so we’re only talking about minor, persistent leaks – and there is only one right way of dealing with it. Replace the offending part.
