Handy hints to help keep your cooling system in top condition

1. Never mix different brands of coolant or inhibitors. A mixture of incompatible coolants can induce radiator fouling and can reduce the corrosion of the coolant. Always flush out the old coolant.

2. Never use coolants that foam as this will lead to increased cavitation erosion of the water pump. Shake the bottle and let it stand for 5 seconds, if the foam has broken and the fluid returns to normal then it probably wont foam in the cooling system. If the coolant has not broken after 5 seconds then it might pay to find a better product.

3. Never undertreat a coolant system as the incorrect ratio of coolant can actually increase the corrosion rate to above that of plain water.

4. Only use the best quality water. De-mineralised is the best, never use bore or spring water.

5. Always check for stray electrical current in the cooling system (all reputable radiator repair shops have this capability). Experience tells us that many vehicles we have examined for electrolysis and chemical corrosion damage are those that have had recent paint/panel repairs.
