I did manage to find a couple of low mileage late engines but finding someone to swap it for £ 150 is virtually impossible! Apart from loosing coolant it also lost all the oil as well! I can do most things but swapping an engine is beyond me. Pity because the Lupo is always well maintained, just changed front brake discs and pads, completely rear brake assembly and new brake drums, brake cables, rear bearing etc etc a few months ago. The engine has only done 130,000 miles.
I might put the Lupo on Gumtree to see if someone would be interested to take it away for parts, well worth it with the amount of parts that I have fitted the last couple of years. Air con models are rare and it is always ice cold in the summer and great for demisting in the winter.
A bit of good news. I went to my local garage to get prices of a set of all weather tyres for the Fox. I mentioned to the guy that the windscreen washer is leaking and he found the leak! It was not leaking at the washer bottle but the pipe that goes from the bulkhead to inside the car got disconnected. He connected it and then found the pipe also got disconnected from the rear wiper motor. All I need to do now is get the pipe connected again!
So glad I don't have to take the wheel arch off, it is getting a bit cold up here!
Many Thanks for all the advice guys.
