Add Coolant or Flush?
Hey,
Low Coolant light comes on and then disappears after a few times. I searched the forums and saw that the sensor might be the problem. When i checked my coolant level, it is low.
Question i have is: Should i just buy 50/50 premix coolant and top off the current coolant in the reservoir or should i get a coolant flush?
The engine is cold, been sitting in the driveway for over 5 hours when i checked.
Thanks,
Kereshen

The relevant TSB is no. 01-040/10
If topping-off won't fix it, you really do need the new coolant bottle. Get it from Finish Line, much cheaper than from Mazda directly through a dealership. You might also qualify for warranty work, if still covered.

If it's low, it's low. Fill it and see if the light stays off. If it's not always low, it's a common problem, although it's not the sensor that fails, it's the float inside the coolant bottle itself. It's absorbing coolant and losing bouyancy. If you have an '05 or earlier, your replacement coolant bottle comes with a new sensor. If it's '06 or later, you re-use the sensor (which isn't bad).

I too had the same question as the OP: low coolant, fill it up with the coolant that says it mixes with all other coolants fine or flush the system?

I HATE SPEEDBUMPS!
Mine is doing it when i drive over 60 mph and disappears when i go lower than 60 mph. I think i might have to go to the dealer to have mine checked.

I zoom therefore I am.
Can you provide a link for finish line please, google search returned quite a few results and after checking some out with no luck I thought I'd ask ![Wink](https://www.rx8club.com/images/smilies/wink.gif)

i would call them before ordering, the part number they're listing isn't the latest revision of the tank. It could be they simply haven't updated their website.. but double check before ordering.

I ended up picking up some, Prestone 50/50 mix from Canadian Tire. Its green in colour and is ethylene glycol based. Seems to be doing the trick and the light no longer comes on.
Thanks for the help guys, Appreciate it!

As a side note that coolant reservoir is hard as hell to read, the only way I could really get any idea was to shine a light down into the hole and look in.
