Penrite Block And Cylinder Head Seal 250mL ADBCS250
SKU: ADBCS250
Penrite Block & Cylinder Head Seal — 250mL
Block & Cylinder Head Seal is a permanent engine block, cylinder head and cooling system sealer formulated with ceramic fibres and copper to ensure a fast and permanent seal of gaskets, fractures and cracks in a vehicle's cooling system.
- Uses the latest ceramic fibre technology combined with copper to permanently seal broken and weeping head gaskets, block and cylinder head fractures, radiator cracks or splits, and leaking engine welch plugs
- Prevents coolant loss and engine overheating caused by expensive coolant leakage
- Seals leaks in one application — very economical compared with mechanical repairs
- Compatible with all modern automotive cooling systems — safe for use with all metals, plastics and rubber components throughout the cooling system
- Compatible with all types of coolants and will not block the cooling system
- One 250mL bottle treats up to 19 litres of coolant (use half the bottle for very small capacity 4-cylinder and fewer engines)
- Colour: Copper | Density at 15°C: 1.08 kg/L | pH: 7–8
Instructions for Use
- Allow the engine to cool sufficiently to safely remove the radiator cap
- If the coolant is rusty or dirty, flush and refill the cooling system with the correct coolant before use
- Shake the bottle well and pour the contents into the radiator or radiator overflow tank
- Fill the radiator or overflow tank to the proper level with coolant
- Turn the heater on full and the fan on high
- Start the vehicle and idle the engine for at least 15 minutes
- Turn the vehicle off and allow it to cool
- Top up the radiator or overflow tank with coolant
- Check that leaks have been sealed — if leaks are still present, a mechanical repair may be necessary
- The vehicle may be driven normally following these procedures
Please note: The product may change colour over time depending on the frequency of exposure to air — this will not affect performance. Ensure the bottle cap is tightened after use. Any remaining product should be used within 12 months of opening.

Packaging: Manufacturers periodically update their packaging and labelling. You may receive the current or a previous design — the product, formulation and part number are unchanged.
Fitment (vehicle-specific products): Vehicle fitment is based on manufacturer and supplier catalogue data and is kept as accurate as possible, but vehicle catalogues are not perfect. Some models had more than one part fitted depending on build date, engine, or component size/variant, and parts on older vehicles may have been replaced with non-original or different-style components.
Before you buy, compare the product images with the part currently fitted to your vehicle — check shape, size, connectors and mounting points. If the part on your vehicle looks different, please contact us before purchasing. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing.
Not sure? Message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm fitment before you buy.
Parts returned because they do not suit the vehicle, where the listing matches the manufacturer's catalogue, are treated as a change of mind and must be unused, uninstalled and in original packaging. Nothing in this notice affects your rights under the Australian Consumer Law.
