Hi it's not over heating, the heating stopped working, checked the radiator and there was no water in it, bought anti freeze, put it in, all worked fine for couple of days, then heating stopped working again, checked and no water, son checked the oil and said there was water in it and the fan wasn't working. Typical always happens when hubby is away. Have taken the car off the road till he comes back to look at it. Was googling and found steel seal, wondered if it was worth a go.
