Got some stuff that came with Tam's Herald . Called 4Life , it is a complete coolant replacement and is put straight into the system after draining and flushing cooling system . It is red but turns yellow if combustion gases are found in cooling system . It will revert to red when fault fixed. it also lowers the running temp of coolant .May give you a more defined answer to head prob ?
Do not know how much it is but for a Surf 2x 5 litre bottles may be needed ?
