I hope the MLOC Team can advise!
The header tank cooling levels, on my 2002 S2 Elise, has started fluctuating 20mm below the min level, when cold, to just below the max level when warm. Images below (I hope) I’ve had the car from new and the coolant level has stayed consistent between the min and max levels until now!!
There is no obvious coolant loss under the car and the oil dip stick and oil filler cap are just showing clean oil.
I have changed the pressure cap but this has not changed the situation.
Im not sure what my options are and PJS/Unit 4 are over an hours drive away and I’m reluctant to travel that distance!!
Any help and or advise is much appreciated
thanks Kevin
