Hi Matt, good effort replacing the thermostat, and good advice for owners replacing theirs'.
Pig of a job on the Diesel. Jules did mine, and well glad he did!!!
Improved performance and mpg. I had fitted a Hans Temp gauge so am now able to watch the coolant temp rise to where it should.
The needle temp gauge seems just for show, (in real terms).
Have you used the ipk diags to give you the temp now? It's quite interesting to see what temp the coolant reaches on varying driving conditions.
They seem to differ between every diesel 75.
Again, well done, you now know a bit more about your smashing 75.
Cheers, JRT.
