200 mile round trip today, motorway and b roads, nothing over 12km ph, all of a sudden I could feel heat when I stopped at traffic lights, temp gauge rising, lucky I was 1 minute from my fathers house, got there switched her off, and could hear the water boiling.

I left it for 2 hours, opened the rad cap, put water in it took a lot, with some coming out on the drip tray, moved the car forward to a dty patch, left it 40 mins, went back out, ground dry, topped it up, this time it lost nothing, drove it home, 20 klms. Temp gauge never moved.

 

Any ideas, I had forgotten the excitement of z driving ...... not

When was the last time it had a new radiator cap? It could be as simple as that and for roughly £10 for a genuine one worth a try?

Check your water matrix area. Could be losing the water inside your cabin mate??

Sounds like a duff rad cap to me aswel.

Whatever the actual cause of the water loss get to the bottom of it fast, over heating is a guaranteed way to ruin a zed engine, could be front water pipes, water pump, turbo feed pipes or plenum water pipes.

thanks Jeff and all, I got the system pressure tested yesterday, he gradually built it up to about 1.5 bar, there was a leak from the rad hose on the left as you look in, the bottom one, also a leak from a pipe behind where the temp housing is, so he took it in today, cleaned the hard pipes, somebody had the hoses off before and there was lots of silicone on them, flushed out the whole system, pressure tested it again, then left it running for 2 hours before I collected it, all seems fine.

Good to hear that Tulip,
