I've done a little bit of modification to my cooling system and am trying to figure out how to tune my fans for the best performance settings.
All I've done is replaced the stock 195* thermostat with a 160* and spliced in SLP'S Manual Fan Control Switch (which works perfectly btw). To make sure my 160* stat was actually opening at 160* I opened the bleeder so check if coolant came out steadily (meaning the stat was open), sure enough it opens right at 160* and works great too. But there was one small problem, the SES light came on and after scanning I found out it was
P0128 Coolant Thermostat
After the SES light came on my temperature gauge dropped down to zero and ceased function all together. Also, both my fans immediately came on I guess as some kinda fail safe to keep the car from overheating. But the stat never stopped working, and coolant flowed as normal! Once I cleared the SES light everything went back to normal and the temp gauge worked again... Should I disable P0128?
Also, my fans are set to come on at 181 and go off at 174 (stage 1) and 190/185 (stage 2) is that a good setting?
