Just been looking at the cooling system on the crossflow. It doesn't look to have a thermostat which was surprising, unless that's the norm with crossflows. In my short drives, it doesn't look to have a cooling problem, seems to get to about 80 degrees and no further yet. The coolant level is just below the level of the top hose which means that the fan thermostat is not submerged although I guess it'll get coolant washed over it in use. What level should the coolant be? The fan works if you take the connectors off the thermostat and make them together. Also the long term owner has taken the heater out of the cooling circuit. The send and return hoses for it are just connected. That makes me wonder. So two questions, what should the coolant level be and is it ok without a thermostat? Cheers Graham
