behr thomson engine thermostat

[Tone]

I decided to fit a 75deg "in head stat" and adjust the pipework accordingly.  The only problem I have noticed after fitting is, the temp sensors for the L-Jetronic are now on the cold side of the thermostat during the heat up period, meaning the fuel trimming for warm up is out of whack...but is barely noticeable and after three miles is back to normal operation.

3-4 mm hole in the stat will solve the problem. I also made this modification on my 2000i.e.

I have now covered 700miles since drilling the by-pass hole, and the temp rises to a steady 1/4 scale rising to half way in heavy stop/start traffic...result!
