Hi
My 94 300tdi 90 with 200k on the clock was running perfectly on my 40 mile commute to the farm and back with no overheating on the local lanes (never exceeding 50mph) but it would overheat when on the A12/14 when at a constant 60mph after around 30 milles.
So I flushed the system using forte cooling system flush and back flushed the rad and fitted a new thermostat (genuine part)
the old thermostat looks like it wasn't closing fully.
But now it will overheat on the local lanes on my trip to the farm and back which it didn't do before, I also only seem to be getting intermittent warm air from the heater... i.e it works on the was to work but not on the way home?
Any ideas what to check and where to start? Ive had the head tested and that is fine (block test)
Thanks
