Today my Escort had its timing belt, water pump and belt tensioner changed, i had been using an OAT Pink colour 30% premix coolant until now as it's what most of the people seem to be using on Escort forums.
They refilled it instead with a regular green IAT 30% premix coolant, considering dumping it all out and refilling with what i was using until now, what do you all who have engines with cast iron blocks and aluminium heads use? IAT or OAT, green or red/pink?
Is one or the other inherently better for an engine with an aluminium head?
