Mine was also on the low line and I added about 1/2 cup of water and all is fine. ed
Manual says replace at 120k miles or 10 years, then 60k miles or 5 years.
Still pretty pricey at $36 compared to Prestone that sells for around $10.
Since the initial fill lasts 120,000 miles I'm curious why you are even contemplating messing with it.
Considering how seldom it needs changing, that sounds quite inexpensive to me.
Sorry for bumping up the old thread... Yesterday I was looking around the engine bay and decided to check on fluid levels, etc. and noticed my coolant reservoir is around 1 inch below the "L" line... Usually don't check coolant since it's rated for 5 or 10 years... but my car only been about 2 1/2 years so far.
Should I fill it back up to the middle with FL-22 coolant? Or should I just add distilled water? Either way I have to go buy it as I don't have any of those laying around, only cheap $10 Prestone or Oreilly coolant in the garage.
$36 is expensive for what amounts to a cup. I don't know the shelf-life of FL22...but potentially you'll wind up recycling it in a few years.
I'd recommend adding distilled water (I did) or go to the dealer and ask them to top it off if you're still under warranty.
Mazda recommends 120k miles or 10 years for FL22 coolant in CX-5.Peak 50/50 Long Life is probably the most compatible. However I would stick with the factory coolant even if it's $25/gallon. It's handy, comes premixed, and you only change it every 60K. I have bigger worries in life than $0.00083 per mile in maintenance.
Dealers would top it off free of charge? I never took my car in for service unless it's a TSB/recall. My car should be under warranty still, since it's only 32k miles right now and I have extended warranty on the car also.
