Loosing coolant when under load over a long distance, ie towing a caravan. All other times solo it is ok. The radiator and expansion tank cap have been replaced with genuine Volvo parts. The system has been pressure tested. The low coolant alarm alerts after about 400 miles. Looking at the expansion tank the level is at LOW. After the engine cools and I release the pressure and the level comes back to normal-ish. I have to put a small amount of coolant in. Any bright ideas. I am stumped.
