Tesco mono Ethylene Glycol pre mixed coolant

[gavin]

i was shopping in tesco today and next to the de-icer was pre mixed 1 litre bottles of anitfreeze it says its mono Ethylene Glycol based mixed with ionised water it was blue in colour, do you think this would be any good for the rex,
im going to be re filling the system after fitting new rad and hoses, can you reccomend a kind i can get of the shelf lets say from halfords - looked there but didnt see any with Ethylene Glycol, what do you guys think

There are now many extended life products in the market place known as OAT or Hybrid OAT coolants (Organic Acid Technology). These have very effective corrosion inhibitor packs that will maintain protection for several times longer than the traditional ethylene glycol coolants with silicates / phosphates. However, beware... OAT coolants can have adverse reactions with other parts of the cooling system in older vehicles that were not designed to use them, ie seals, gaskets and hoses. That is not to say that all OAT coolants will cause problems, only I personally would not risk it when adequate performance (cooling, antifreezing and corrosion prevention) can be obtained from the cheaper traditional alternative - 50/50 EG mix with demineralized water changed every year or 2. In answer to your original question though Gavin, the Tesco product should be fine and the cheaper products on the shelf in stores such as halfords will also be the basic ethylene glycol type. Hope this helps.
