coolant level sensor light

[sunil sood]

the car is a 1993 model,190e-1.8 .

last night while driving on the motorway at night, i noticed that coolant level light in the dash was on, but not fully,just partially.
by this i mean it appeared to be on but it was quite dim.

the coolant temperature was normal at just above 80c.

i checked the coolant in the expansion tank and the level was normal

does this point to a dirty coolant level sensor connectors?.

is there anyway of cleaning the coolant level sensor?

or does it need replacement?

any comments appreciated. :?:

My dashboard light is always on if its connected - so its not!

As I'm not loosing any coolant and as I have the ability to lift the bonnet to check the levels I'm not going to spend a second or a penny fixing the problem!

Mike.

ps I cleaned the connector but it did'nt work (obviously)

Hi

I would try bridging out the connector for the low level coolant sensor. If the light goes out. Then replace the sensor. Even from the stealership they are only about £12

thanks for the advice.

i had a look at the sensor terminals and connectors-

the sensor terminals were rusty/dirty-cleaned them,then applied some wd 40.

the connectors were also dirty-so cleaned them, and wd 40 was applied.

the coolant level sensor light does not come on in the dim mode at night.

problem fixed!! :lol: :lol: :lol:

Sometimes bulb holders can fall out the back of the instrument panel or partitions between bulbs can get dislodged and result in the appearance of a dimmly illuminated waring symbol.
