Drove parents to gloucester yesterday, coming down the motorway on the way home, coolant light came on, I come of the motorway, and as I pulled into services, the car started to overheat (red light came on)
I filled up coolant tank with water to do me till I got home, which is about 20 miles of A Roads. The temperature dropped back down to normal almost instantly.
unfortunately, I got literally half a mile down the road, and the coolant light came on again. I pulled into the Asda store at the side of the road immediately, and found the water had all gone. Took a good 4 litres to get the level float to come up, but as fast as I put the water in, it came out again.
I stayed in the Asda car park and got a recovery truck to collect me, as the last thing I wanted was to risk overheating the car - causing bigger problems than I already have.
Im going to jack the car up shortly and put a hose in the filling hole and turn it on low, look for the leak.
Will flush the coolant system while I am there. Not sure if its going to be the Rad, expansion tank, thermostat housing, pipe work or water pump. Anyone know of anything it could be losing water that fast?
