TxDII said:I finished the thermostat modification this weekend and so far everything seems to be working well. Based on my ScanGauge, I have temp readings of around 188 to 190 at idle and 193 at highway speed. Where I really see a difference is when coming to a stop from highway speed. Before the change, my temp would climb to about 206 at a stoplight, then drop once I was moving again. Now the reading increases only to about 195 while stopped. It was about 93 degrees outside today when I checked these temps.
I used a similar setup to the others in this thread:
-Meziere Thermo Housing (1.25?) w/180 degree thermostat
-GlowShift Water Sender Attachment
-BMW lower hose
I drilled a 1/8? hole in the thermostat, and on the GlowShift adapter, I added a petcock drain in the temp sensor fitting to bleed the air out.
Thanks again to DiscoArt, JohnB & Jeffro for posting their pics and findings.
Here is another interesting link I found to modify the thermostat on an MGF (same concept ? relocate the thermostat from bottom of radiator to top).

Very nice. Looks like the 1.25 is the best fit. Good job
