In my gregories service guide on how to change the coolant, it sais to place three cooling system pellets (Part No 9214 0053) into the upper radiator hose. What on earth are they? Even google only had 3 unrelated results.
the pellets are actually crushed walnut shells, the bits flow around with the coolant chipping any buildup away from the back of the water pump seal helping to stop leaks.
Now if the poll was 'Would you let someone else root your missus' then the answer would be different. That would depend on what their missus looked like and if you could root them.
