FAQ's

Once the engine has been started and reaches operating temperature, GasketGuard™ is distributed through the coolant system. GasketGuard™ unique formula is drawn to the CO2 leak, thus locating the damaged area and sealing the damage with a fast acting thermo-chemical bond. This is as strong as metal but more importantly, flexible to withstand the thermal expansion of the engine.

GasketGuard™ has a 99% success rate that it will seal your blown gasket or cracked head. Failing this, you will receive a full refund under our 'money back guarantee'.

Our unique formula uses nanotechnology which targets the precise location of the damage and creates a chemical reaction seal once a leak is detected, unlike conventional formulas on the market, which use fillers and fibres to create a block. This method is not precise and can cause unwanted blockages in your coolant system, this method is also not permanent as the fillers and fibres can become loose over time causing the seal to fail. Our Seal is guaranteed to be permanent!

If you have used another product beforehand which has failed, please flush your coolant system with FlowFlush™ or an alternative coolant flush before using GasketGuard™. (If you do not have a flush formula available, then flush your coolant system 2-3 times with water.)

Yes, GasketGuard™ is safe for use in all types of engines including petrol, diesel, and hybrid.

GasketGuard™ is designed to seal leaks in the head gasket, engine block and core plugs, among others.

It is not recommended to mix GasketGuard™ with other coolant additives as it may affect the performance of the product.

GasketGuard™ starts working immediately upon application, but the time it takes to seal a leak may vary depending on the size and severity of the damage.

While GasketGuard™ is primarily used to repair existing leaks, if an early leak is detected, it can also be used as a preventative measure to help extend the life of your engine's gaskets and seals and prevent further damage.

Yes, GasketGuard™ is compatible with all types of coolant including ethylene glycol-based and propylene glycol-based coolants. However, for best results, empty your coolant system and use plain water while sealing the leak and then replace with fresh coolant. This is ideal to ensure other unknown contaminants are not present in your coolant system, which could affect GasketGuard™.

GasketGuard™ only needs to be applied once to seal a leak permanently.

Yes, GasketGuard™ is safe for use in vehicles with aluminium engines.

No, GasketGuard™ does not have any adverse effects on engine performance when used as directed.

Yes, GasketGuard™ can be used in motorcycles with a coolant system as well as other types of vehicles. For motorcycles, only half a bottle is required.

Yes, GasketGuard™ is formulated to be environmentally friendly and safe for disposal.

Yes, GasketGuard™ is safe for use in turbocharged engines.

Yes, GasketGuard™ can be used in commercial vehicles such as trucks and buses.

No, GasketGuard™ is not flammable and poses no fire hazard.

Yes, GasketGuard™ is safe for use in marine engines.

Yes, GasketGuard™ is compatible with hybrid vehicles.

Yes, GasketGuard™ is suitable for use in agricultural machinery such as tractors and harvesters.

Yes, GasketGuard™ is effective in sealing leaks in both gasoline and diesel engines.

Yes, GasketGuard™ can be used in racing vehicles such as cars and motorcycles.

Yes, once fixed, we guarantee that its seal will not fail. If the seal ever starts to fail, simply get in contact and we will send you an extra bottle to restore the seal.

GasketGuard™ should always be kept out of reach of children. Avoid eye or skin contact. If eyes or skin become irritated with GasketGuard™, rinse with cold water immediately. If swallowed, do not induce vomiting. Call the poison centre immediately and state reference UFI number '6000-A0PG-V00M-2VSG'. Be aware when working around a hot engine. In particular, backpressure may cause coolant to be thrown out from the radiator/expansion vessel. Therefore, always wear the personal protective equipment described above. Avoid getting your face too close when the engine is hot, and always allow the vehicle to cool completely before removing radiator cap or changing coolant etc.
