No leaks obvious but some fluid top up necessary every few weeks. Maybe leak is intermittent from somewhere in the plumbing. Contemplating a coolant drain, flush and renewal as over 8 years (130,000 kms) this may never have been done. Coolant temp rarely exceeds 90 level and have never noticed or heard two electric fans operating either. Only cap in system is on the ballast tank. No signs of pressure in the system as would be caused by a head gasket problem but have noticed main top hose sucking flattish as the engine cools. As with all things Mercedes a clue from another owner could set the matter right at reasonable $$$$ impact! Can anyone out there help on this one. Thanks
