Alex350z Posted May 30, 2016 Share Posted May 30, 2016 I'm looking at changing my coolant, not the full system, just draining the radiator and refilling. I will use genuine stuff, but it looks like what's already in there isn't the same? Is it a bad idea to potentially mix two coolants together? Cheers Quote Link to comment Share on other sites More sharing options...
GMballistic Posted May 30, 2016 Share Posted May 30, 2016 It can be a bad idea to mix two different coolants as it can effect how the coolant works or worse case scenario cause some sort of chemical reaction clogging your coolant system/pipes up. You're supposed to always mix the same colours together AFAIK. Quote Link to comment Share on other sites More sharing options...

Cheers Why would you just drain the radiator coolant and not the whole system ?. Not having a go, just seems pointless imo. Quote Link to comment Share on other sites More sharing options...

Well I've read it's a big job to drain the block and bleed the system, so I thought for £15 I'd just drain the rad and top it up with some fresh stuff. Maybe I'm mistaken?

Vlad Posted May 30, 2016 Share Posted May 30, 2016 For £15 and possibility of doing long term damage to the engine? I would drain it all and fill with new genuine Nissan coolant. Doesn't take that long. I did mine couple of years ago...just done some research prior to that on how to change and bleed coolant and was done in like 1-2hrs without any issues.

Well this is why I asked, I didn't just want to go mixing stuff together Quote Link to comment Share on other sites More sharing options...
