yeah, just tell the dealer the coolant light is coming on for seemingly no reason, and they'll replace your box. then no more light.

in the meantime, you might try putting a little distilled water in the coolant box. it's the clear probably dirty looking box in the front next to the battery with the warning cap.

olddragger told me to do that, and it worked for a little while.

why dont you try adding a cup or 2 of coolant to the tank to make sure you arent actually slightly low? because in your situation described it sounds like it might be.

everyone says its "fine" and 90 % of them that actually added some after i told them found the light went off and stayed off, the others actually had a bad sensor and needed a new tank. so you can go ahead and sprnd the money on the tank or you can try adding a litte.

topping up the fluid will work for a while, but it's not a permanent fix. I've had mine topped up to above the F mark a couple times now and I'm still having my light go on at high RPMS. The only way to get it to turn off is let the revs drop below 2k for several seconds. The first top up solved my problem for a good 6 months, and every time after that it's become more frequent.

I cannot find the TSB either, but in this article, they mention it under Mazda and provide the TSB number.
