Volvo 850: coolant level with expension tank.

Hi Pierre,

My 850 coolant level varies about 20mm above and below the centre line of the tank, depending on "how it feels". I never have to add any. But I often wonder why it varies, or where it goes to and comes from. I keep the nominal level at half way which I think is where the line is.

Regards Barry

Thanks Barry.

When the engine is cold, the level is at the max (centre line of the tank). When the engine is warn I can reach almost the cap, and I did not notice this previously.

Perhaps this is normal!!!!

Thanks
