Is this product for you?

Scientifically formulated to chemically repair minor head gasket leaks or small cracks allowing coolant to enter the combustion chamber, Rislone’s Block Seal Head Gasket Fix is a simple and cost effective solution to a difficult problem. Unlike other products which may require the coolant system to be drained, this product from Rislone can simply be added to the radiator regardless of the coolant currently being used. Once added to the cooling system, the heat from combustion is used as a catalyst to harden to repair fluid. Once hardened, the repair solution is generally stronger than the standard head-gasket material, creating a ‘ceramic-like’ seal perfect for preventing future leaks. This product is suitable for both petrol and diesel engines, with both cast iron and aluminium block constructions. So, the next time you have a minor internal coolant leak, try Rislone’s Block Seal Head Gasket Fix to keep your car off the hoist, and on the road.

Whilst this product is designed to repair minor issues, it may not be a suitable repair method for moderate or large issues, and may cause further problems in some circumstances. Before use, if you are unsure please check with your mechanic to ensure that this product provides a suitable repair for your issue.

Delivery Fees

Your delivery cost will vary depending on the size, weight and location of the products you choose to purchase as well as your delivery location of choice. Normally the larger the item, the more expensive delivery will be. Extremely large goods (ie. Items requiring a two man lift) will also incur higher delivery rates.

Please note: As we use couriers to deliver all parcels, products cannot be delivered to an unattended address. The courier will require a signature from an occupant at the specified delivery address at the time of delivery, if no one is available to sign for any parcel a card will be left and the parcel re-directed to the nearest Courier depot. You will then be responsible for collecting the parcel from that depot or paying an additional charge for re-delivery.

Supercheap Auto recommends all deliveries be shipped to a location that is attended during business hours, whether that is a home, work or other address, to minimize any redelivery delays and/or fees.

You may incur additional delivery fees/freight charges within the checkout (in excess of the fees and charges specified above) for:

  • Large quantity or bulk orders.
  • Express or urgent deliveries; or
  • Non-stock and/or bespoke items

Bulky Items

At checkout, you will be notified of shipping costs for your approval, these are calculated automatically by the site in accordance with our courier companies' freight charges via a courier aggregation application (supplied by Temando). Bulky items are those with either a high weight or large cubic volume. Products are allocated as bulky as determined by the shipping methods of our courier companies.

Please note if your cart contains non-bulky and bulky items your cart will be calculated accordingly.

Delivery Time Frames

We use a selection of courier services with delivery times of between 1 - 10 business days after dispatch for smaller items, and 3 - 10 business days for larger items, depending on your delivery location. Courier deliveries are made during business hours, Monday to Friday only.

P.O. Boxes and Authority to Leave (ATL)

We are unable to deliver goods to PO Box addresses as all delivery orders are sent via courier services. Unfortunately we do not currently offer Authority to Leave (ATL).

International Shipping

Unfortunately Supercheap Auto is currently unable to provide international shipping.

Reasons for order delays

  • Entry of an incorrect or incomplete address during checkout.
  • The address had no-one to sign for the parcel.
  • Incorrect payment information was entered against the order. Please double check all details at time of checkout as your order will only be created upon receipt of payment.
  • In the event an order is flagged for verification we may need to get in contact via phone before dispatching some orders. Personal details may need to be confirmed for fraud prevention if we are unable to verify the shipping destination to protect the card holder, and this may delay shipping.
  • Occasionally if a particular product is in high demand we may need to supply product from outside of our standard delivery network. This can cause delays in dispatch if orders are directed to regional locations etc.

If your order is not received within the quoted delivery period please check your order progress via our Track & Trace portal, alternatively contact our Customer Support Team on 1300 175 010 or complete our online enquiry form. We will generally respond to online enquiries within 24 hours.

Did not work so not happy.
VT Commodore
I was loosing about 500ml of radiator fluid a week on my VT Commodore. The engine had been cooked about 2 years ago because of a faulty radiator fan but wasn't having any real issues until recently. Didn't do a head gasket leak test but the oil cap was milky and with the loss of coolant, it pointed to a head gasket. Followed instructions, which were pretty to manage and it's been 1 month since with almost zero coolant loss. VT Commodore is on its last legs so a head gasket repair was out of the question - this was a good solution and worked for me.
so far worked well added to original coolant have done 70 hours . oil is still clear . was a john deer engine with corrosion around the liner allowing water into the oil not a compression area just water into sump tractor is old and not worth rebuild . so in this situation very effective highly recommended
Finally stuff that works
Iv used other stuff in the past that works but only for a little while. My head blew badly, water in oil sump and through this stuff in and drives like a dream. Will see how many kind I can do but have already done over 1000kms
Immediate Improvement BUT
Applied the full bottle as per instructions and noticed an immediate improvement. After a week still not totally fixed with coolant system pressurised and no traces of the copper in the coolant. Then looked at the reviews here and checked the Rislone website. Instead of applying anoth bottle of the head gasket fix, I used a bottle of liquid Copper Block Fix. Kept checking overflow bottle and topping up radiator. Traces of copper in the coolant reduced and I persisted with another bottle of the Copper Block Fix. Finally after 4 weeks, I am now satisfied with the end result. Radiator now has a vacum when the radiator cap is opened instead of being pressurised .
Don't waste your money
I just bought this product and it is very expensive $70 ( was on discount for $4*), I thought it is a good product and wanted to give it a try, so my sincere advice to everyone is don't waste your money. Why? because this product is exactly is the same as the radiator stop leak "Rislone Liquid Copper Block Seal - 510g by the same company which is just ~$22". They just put it in a non-transparent bottle so customers will think they are different and buy it, but after opening the bottle, they are identical and from the company website, the chemical components of the two products are the same. Importantly, their liquid copper stop leak ruined a brand new water bump in my wife mazda 626, year 2000, and my mazda 626 1999 (twice) and in 2002 my beloved Ford Telstar Tx5 overheated because it clogged the radiator. I didn't know what was going on until I opened this Rislone Head Gasket Fix and noticed it is the same product that ruined my cars. I hope supercheapauto, if they are honest, to allow this review. II'd apprecite if I can get a reply from supercheap and Rislone.
