I tried the 180 thermostat and then wondered what if I didn't have one in at all. So to keep the o-ring for sealing I removed the guts out of the original 190 thermostat.
It worked out great. On a 90 degree day the water temp stayed at 160 even with the air conditioner on and in stop and go traffic. My automatic transmission trans was cooler also. It could be just my imagination but my Turbo temp and manifold temps seemed a little lower.
The engine turbo temp auto shut off also shut my engine off sooner. I am really pleased with the results. Now when I pull a hill with a full load I can cool down on the downside before increasing the temps again.
