I’ve recently started to restore my father in-laws 1967 250sl.
He purchased the vehicle in 1983 and used it for some time until he parked it up in his garage covered by a sheet and forgot all about it!!
Then I met his wonderful daughter (my now lovely wife) and then discovered this hidden treasure. I pestered him to try and get it running.
The car is in need of a good service and a clean up, I’ve changed the plugs, points, condenser, dizzy cap and HT leads, dropped the fuel, cleaned the fuel filters and put a new battery on and to my amazement it started first time.
After running the car for 5 mins the car started to get hot, I then thought the water pump must have ceased up. I stripped it down and found it running free. On closer inspection it looks like the thermostatic valve is not working so a new one has been put on order. The work continues…….
Thanks to Naj for the help and any other advice would be gratefully received.
