Default A light with a fan and one wavey line about it? 1996 Mustang GT

Hey I'm asking for a friend who just Bought a 96 4.6L and he says the once in awile this light pops up. He thinks it means the it's running rich. I don't get fancey lights like that so I couldn't tell him. Like the title a fan with one wavey line about it going from side to side.

Thank

That's definately not running rich....

Straight out of the owner's manual:

Low Coolant Warning Light (4.6L Engine
Only)
This light tells you that the coolant is low inside
the coolant recovery bottle and that you should
add more coolant.
This light comes on for a few seconds when
your ignition key is turned to start, but should
turn off when the engine starts. If this light stays
on, check the level of coolant inside the recovery
bottle

No he just bought the car and had all the fluids changed.

Well, then the coolant level sensor is bad then. But that's what that warning light means.

If you find out how much this sensor is let me know. Mine went off a few years back after a hose came loose and even after refilling the coolant and reservoir, it has stayed on. Never changed it though because it still passes inspection.

Previously, I had an intake manifold gasket go bad. It caused coolant to leak, which resulted in low coolant in the reservoir tank. There is a little float in there that measures the coolant level and when it's low, it trips the light. When my coolant was low, the float stuck at the bottom, and despite filling up the coolant level after fixing the gasket, the light stayed on. I got a long screwdriver and poked it at the float to free it. Then the light went off.

OP if the light looks like this (see below) it's low coolant. Believe it or not, there are people who know about Mustangs on this forum.
