i keep loosing water out of the expansion tank (overflow hole i think)... i have recently replaced the water pump, thermostat, rad fan switch and expansion tank cap (new blue cap fitted)
the fan still isnt switching on, i recently had to hard wire it to work, but the bearing has gone as well :/
also the temp guage isnt working - but i dont think this would affect my water loosing issues :/
im going to order a new temp sensor and fan this evening, but what else could keep causing the water loss?
