look im no engineer or scientist. just a backyard wrench. but you guys are making this harder than it has to be.
for my car and i can only speak of it the temps run at 100 degrees C which is the were it stays all day so thats the operating range at this time. bu installing a 180 tstat my temps should drop to around 80 C. that will be the normal range. i dont see my temps jumping back up if the flow is released at 180 instead of 195.
jturkel for a 20,000$ car with a s/c 100$ is cheap mod to try. the separation is free. do it!!!!
