Tectaloy XTRA COOL Corrosion Inhibitor Concentrate is formulated using the latest inhibitor technology. It offers superior long-life corrosion protection to all metals used in the modern cooling system, such as aluminium and alloys. It is a gentle formula, not harming radiator hoses and reducing corrosive attack on alumimum and cast iron.
When used as directed, Tectaloy XTRA COOL Corrosion Inhibitor Concentrate lasts for two years or 40, 000 kms (if you use demineralised water) and delivers 100% corrosion protection. If you need a coolant for heavy-duty application, see the XTRA COOL GOLD Coolants, or, if you require a heavy-duty coolant with anti-freeze protection, see Tectaloy Unlmtd Type A coolants.
This listing is for the 500mL bottle, but it can also be purchased in a 20L bottle.

3. Use Tectaloy Mukowt if the cooling system is dirty
4. Add Tectaloy Xtra Cool to the radiator at the correct dose rate and then refill the radiator with clean, soft or demineralised water. Do not over dilute as this will adversely affect the performance of the product
5. Run the engine, bleed the cooling system correctly, ensuring the thermostat and heating circuit is open and check the level when cool
