low coolant light

[jgfiveoh]

my instrument cluster has a low coolant light but it has never worked. there is no sensor on the overflow tank. it's a 90 5.0L lx.

was the coolant sensor an option or standard equip for my car? i thought that all 5.0's had the coolant sensor? was mine there at one time but now missing?

where is the harness for the sensor located at?

im pretty sure it's part of the overflow cap, seeing as how theres wires going into it, thats always where i thought it was.

 

[jgfiveoh]

ya, its supposed to be part of the cap, but someone must've just put an el cheapo cap on there because there's no sensor or wires that i can find tucked in somewhere.

it is an E coded VIN

 

[carbed87]

huh, well i wouldn't be too concerned if it's not going off. just check your coolant whenever you check your oil.

Only GT's came with a low coolant light. I don't know why your LX even HAS the bulb installed. I would just pull the cluster and take the bulb out.

I have a low coolant light in my Stang, and it is functional.

Same here.

i guess that's what i'm trying to figure out first is whether all 5.0's had the light or just the GT's?

My 91 LX has a functioning Low Coolant light and sensor......It just tends to function too often, even when full of coolant.

Its a waste and it dosent work right.. Just check it regularly..

 

[TheBocSez]

If you have a low coolant light and you remove the sensor, replacing it with just a regular cap; will the light stay on or off?

I have a low coolant light on my LX...

i had the same prob, cleaned it no help. just unplugged it no prob after that. just keep an eye on fluids like you should anyway.

I believe it was 90+ when the LX was equipped with the low coolant light. Previously it was GT only.

I concur. Even though it may be funtional, I still wouldn't trust it.

On the 87-89 cars..only the GT's had the coolant lights. The LX's have the wiring to make it functional, but only the GT's came fully equipped.

On the 90+ cars, i beleive it was either standard on all 5.0's are part of some package. Either way, you could get the light on a 90+ 5.0 LX

With the plug unhooked, the light won't function. So if you don't have the sensor in the cap, all you need to do is find a cap with the sensor in it and locate the plug harness somewhere in the front driver's side harness and plug it in

thanks for all the replies. i found that i do have the harness for it. it was tucked down by the battery and i couldn't find it at first.

i also read in my owners manual that all 90 5.0's had the coolant sensor.

not sure if i'm going to use it or anything, just wanted some clarification on whether i should have it or not. i thought i had heard at one time that only GT's had it and i basically wondered what the stipulation for it was.

anyways now i and hopefully others learned something. thanks

Your manual is wrong.

Your manual is wrong.

ok...show me otherwise

My 90 is proof.
