K-Seal Coolant Leak Repair 236ml

Product Information

Coolant loss can happen for many reasons, some more serious than others. Here are the most common that you may encounter to help you to understand why these occur so you can hopefully prevent, diagnose and find the best solution to: Worn-out radiator hoses:

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.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. 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. What happens is this: These sealants are in liquid form within the coolant and harmless. However, as soon as it encounters air – usually at a leak – it solidifies and seals the leak. What it’s supposed to do. The problem is that in old, unsealed engine cooling systems there is often air trapped inside and so the sealant solidifies in the engine. Usually the first thing to get clogged is the heater matrix which has quite narrow channels, then the cooling radiator and then the engine cooling galleries. This latter is very dangerous because the solidified clumps of sealant prevent various nooks and crannies inside the engine from being cooled by the coolant, so they overheat and distort.

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? 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. With a leak, you will smell the coolant and possibly see some steam. There could also be pooling of the cooling under the vehicle, with more leaking as the gasket continues to deteriorate. 5. Bad Heater Core For starters, without the right amount of coolant circulating through the system, the engine can overheat. Additionally, you may hear a lower groaning sound coming from the pump before it fails. 4. Leaking Thermostat HousingYou 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. Coolant Seal cannot repair leaking hoses. Are there any special precautions I should take before using Coolant Seal?

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? Remove the radiator top hose and pour Coolant Seal directly into the cooling system. Replace the radiator hose and carry out the treatment as per instructions or However, more serious repairs, such as a radiator replacement or a blown head gasket may be beyond your level of expertise. Don’t be afraid to jump to step number five if you need more help. 3. Fill and Bleed the Cooling System 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. 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?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.
