Auto Agencies Irontite Cooling System Sealer 375ml | 960101A

Kauri Auto Parts — brand-new aftermarket and OE-replacement parts, dispatched from within New Zealand. Every price includes GST.

Irontite cooling system sealer formulated to seal cracks and stop seepage. Its compound gels and hardens quickly when it contacts air or combustion chamber gases.

The non-vegetable fibrous material is designed not to pack into smaller coolant passages. Radiators and blocks can be reverse flushed without disturbing the sealing effect, and the formula contains no soluble oil.

It helps prevent rust, corrosion and electrolysis in systems using cast iron, copper, bronze or aluminium components, while providing a protective coating throughout the cooling system.

Confirm this part number against your vehicle's existing part before ordering.
