Service part 2

I went to my local motor factor and the radiator cap was there so I took it leaving me £5 lighter. I decided to swap it there and then and I wasn't really surprised to fin that there was no pressure when I removed the old cap. It was obviously way overdue for replacement. When I got back I removed the cap to top up the radiator and there was some pressure in the cooling system so all seems to be well. I'll be still flushing the system out and refilling with fresh coolant. I've had no problems and I want to keep it that way!
