check coolant level?

[melomaniac]

my dash keeps alerting me that I should check the coolant level. the gauge seems to be in the right position. I'm hesitating to add too much. nothing has been done to radiator or expansion that, and I see no leak in the garage.

any guesses? hints? advice?

I am not a professional. This is just my opinion. I could be wrong.

Well. First things first. Did you check the coolant level? Is the coolant low? And what gauge are you looking at? I am not familiar with a Coolant level gauge. Are you looking at a Temp Gauge? There might not be a leak in the garage because........there is very low coolant.

What year and model is your vehicle? Start by checking the coolant level in the rad and the expansion tank. If its low add some according to the manual. Check it regularily to make sure its not leaking coolant.

Possibly needs bleeding. If there is an airlock somewhere, the coolant might not be hitting the sensor correctly..

Drain the system, get the front end of the car up in the air, then replace coolant with ratio you would like. Run the engine with the cap off for a bit to really give it a good going-round

Just change the sensor Dabsy, its a cheap part and the new version is more reliable. Its not even that hard to change.

Already on my "To-Do" list Brett !! Along with the LCM, rear bulb-holders x3, tyres x2, pixel-repair on MID, oh, and a service

Ahh, aint love grand. The list that you always intend to knock over, but never seem to find the time.

Exactly

no luck with bleeding. when I check on a cold engine, level is correct. thee 'check coolant level' shows up only occasionally, and as far as I can tell it has little or no correlation with how long I've been driving, or how hard for that matter...
