Do I have to flush my cooling system?+

Not always. A flush may be recommended for best results where there are contaminants or incompatible additives. Follow the supplied instructions.

How much HyperSeal Clear do I need?+

The proposed treatment quantities, subject to confirmation against HyperSeal's approved 500 ml formulation instructions, are:

Engine size                                Quantity
Up to 2.0 litres                          - 1 bottle
Over 2.0 litres to 3.0 litres       - 2 bottles
Over 3.0 litres                           - 3 bottles

Can I use HyperSeal Clear with antifreeze?

Not all coolant formulations are suitable for use during treatment. In particular, long-life and OAT-type antifreeze require compatibility checks.

Follow the approved HyperSeal preparation instructions before application, and restore the correct vehicle-manufacturer-specified coolant after treatment.

Does HyperSeal Clear permanently repair a blown head gasket?

HyperSeal Clear is designed to help create a lasting seal in suitable internal head gasket leaks.

Results depend on the location and severity of the leak, the engine's condition and correct application. Major mechanical damage may require conventional repair.

Do I need to flush my cooling system first?

A complete flush is not automatically necessary in every situation. However, flushing may be recommended or required depending on coolant compatibility, contamination or the presence of previous sealing products.

Follow the approved product instructions for your vehicle and cooling system.

Can HyperSeal Clear stop overheating?

Where overheating is caused by a suitable internal coolant leak, successful treatment may help address the underlying coolant loss.

However, HyperSeal Clear cannot repair unrelated faults such as failed water pumps, defective thermostats or blocked radiators. Never continue running an overheating engine.

Will it repair a severely damaged engine?+

Not necessarily. Extensive mechanical damage and serious overheating can require professional repair.

Why doesn't HyperSeal Clear offer a money-back performance guarantee?+

The reason HyperSeal Clear doesn't offer a money-back performance guarantee like other products do.

We believe in giving customers better value from the start.

Some head gasket repair products include additional money-back performance guarantees, which may involve eligibility requirements, diagnostic evidence and a claims process.

At HyperSeal Clear, we've chosen a different approach.

Rather than offering an additional performance guarantee, we focus on keeping our treatment competitively priced and making it accessible to customers looking for an affordable repair option.

We believe this offers straightforward value, without customers having to pay a higher price for an additional guarantee they may never need.

Our approach is simple: a quality head gasket repair treatment, clear instructions and competitive pricing.

As with any head gasket repair treatment, results depend on the nature and severity of the fault. HyperSeal Clear is designed to help seal suitable internal leaks, but no treatment can repair every type of engine damage.

Your statutory consumer rights remain fully protected, including your rights if a product is faulty or not as described.

Is the repair guaranteed?+

No repair outcome can be guaranteed for every vehicle or condition. Results depend on correct diagnosis, proper application and the nature of the fault.

Can I drive if my car is overheating?+

No. Stop safely and allow the engine to cool. Seek mechanical help rather than continuing to drive.
