Why does my engin cut out at just under 80 degrees
My ‘82, w123, 200 Manuel transpmission, cuts out at just under 80 degrees. When I start her up again I have to really rev it up to 3000rpm to stop it from repeating itself. I've just recently bought it so I'm not too clued up on what's going on, I feel I should mention that the interior cooling fan isnt working, and no it's not the fuse. I can only drive 5 kms before I have to stop and let it cool down for 20 mins.
I've tested the thermostat and it works correctly. What could it be?
