Coolant blowing out of filler cap
My 9-5 SE Turbo suddenly overheated and blasted coolant out of the expansion
box filler cap accompanied by an alarm and sid display to refill coolant fluid. I
stopped and raised the bonnet to find coolant level up to cap level and coolant all
over the engine compartment. The top hose from head to radiator was flat. My
immediate thought was water pump failure. I refilled tank to correct level and next
time of driving the same occured. Any suggestions most gratefully received.
