Not quite as dramatic as this:
Troubling just the same. The '94 Mustang beater is reporting "Low Coolant" on an idiot light. Bad on me for not catching it sooner. There is a reason they call them "idiot lights". Sigh. Luckily, the "No Coolant" light is not on yet =). Looks like the thermostat housing. On it tomorrow, it's supposed to get cold here Friday.
