for what its worth ,my son wrecked a couple cars with Renault diesel motors [ Suzuki GrandVitara] same motor as a traffic sept north south ,a local mobile mechanic bought some parts off us ,he said he had a customer who had a car[ grand vitara diesel] , that was filled with the wrong coolant and he had to replace all of the plastic bits[ radiator end tanks t/stat housing ,etc,] in the cooling system ,as said coolant had reacted with ,these bits made them brittle ,he said only use red coolant ,he noticed the colour of the header tank when removing parts ,,told me the story .i have no reason to disbelieve him .PUGS maybe it was a coincidence
