What Does This Dash Light Mean ?

[93_LS400]

Question..

I have a 93 LS 400. Now and then, a little yellow picture of a radiator blinks on intermittently at the bottom of the dash. ( stays on for 5 minutes, then off for 45... but randomly )

The coolant level seems OK , as do oil,trans,brake fluids. There's no description of that light in my manual...

What's the light mean ? :shutit:

TIA

Hi

Attached (if it worked) is a scan of the dash layout with legend.

If you need more just ask

looks like the coolant then. Anyone know of any problems in this area with the sensor or anything ?

Yeah, they are prone to leaking around the top up lid, not by a lot, but the sensor is really sensitive. Just keep your eye on the level every now and then, or try a bit of clear silicone, if you can identify the leak.

Followup; the coolant level is fine, but the light keeps coming on. There seem be sensor wires running into the clear coolant reservoir. If the level in the clear tank is fine, should I worry ?

Or is there another sensor at the bottom of the block or something.... that might be airlocked or something...

If the level in the clear tank is fine, it sounds like the sensor itself is knackered. My understanding of the warning lamp, is that it only comes on when the water level is low, therefore if yours isn't, then you have a faulty sensor.
