Heading away for 4 weeks solo into the outback in June/July so not too hot.

Don't think the Patrol has ever had its cooling system flushed. It's never overheated and I don't think I've ever seen it hit 94 degrees.

It's a 2013 Y61 CRD and has been regularly serviced.

Just wondering if I should flush it out as a wise preventative measure or do cooling systems these days not need to be touched unless they play up??????

Thanks for any advice.
