Early morning dumb question:

[Oldmactech]

My 03’ 3.0 gets minimal usage. (Has had a headgasket about 15k ago). Low Coolant light comes on about every 100 miles- no signs over overheating (sat in traffic for 20 mins yestrday, no symptoms).

I dutifully top the tank off with a 1/2 cup of coolant mix. The level indicator plunger is always at the full extension before adding.

Admittedly, the overflow tank is Amazons best (cheapest) tank. Any possibility the float, sensor, anything else just might not be functioning properly? I think I read somewhere that the magnet gets loose or something.

There are never any drips or smell associated. Doesn’t appear to have coolant in cylinders based on recent testing.
