Hi, I put a different coolant (brand g8) without adding water as it was below the minimum level and I’m going to be doing a lot of driving this week, in my bmw 2013 520d series. Now I’m worried this will ruin the engine. Should I go to a mechanic to flush it?

ok so if two different types of coolant were mixed it can cause issues longer term because it can cause a reaction between the two different types and cause blockages within the system also if you put coolant in that's undiluted it can also cause the antifreeze to not work effecting the running temperature of the engine. I would get the system flushed and refilled with the correct mix of one type of coolant. Please let me know if you have any further questions and thanks for choosing JustAnswer

Thank you Kevin! Is it something I should do immediately or can I get to my destination today and then do it? Also, can you recommend a garage in Derry (Northern Ireland) where I can do it?
It’s something that should be done sooner rather than later . Your trip should be ok to make

Perfect! When I get to Derry then I’ll seek for a bmw garage.
