Opel Corsa 1.4i Utility Coolant Change (Opel Gamma) 

Hi . If it's the same model You are most probably talking about the air pipes that goes from the inlet manifold to the purge valve

Hi there. Generally you should be fine. There are many explanations for the four colours. It has to do with the ingredients and composition. Generally the green and red is common use and the pink and blue are for newer year model vehicles. This explanation is very basic but it's the easiest way to look at it. You can google further information. I prefer the evron premixed for my vehicle as it is balanced and safe and has a good price point. There are more expensive types but I think it is overkill. Just don't use water only. Coolant should be like all other moving parts be changed out every year. This is what I prefer for my vehicle and may not be preferable to someone else.

Thank you , I will look into it

Hi I am not a parts dealer. And it will be best just to message me here. I will respond as soon as I can

Hi . You can use the green one, preferably the premixed one . It is for winter and summer. Try your best to do a coolant change every 6 months , it will help keep your temporature down and also save on your inside engine corrosion
