Are there any advantages/disadvantages to using a 160 deg. thermostat
versus a 195 deg. thermostat? I have a lot of knock and ping that I
suspect is due to excessive temps in the combustion chamber since my
timing seems dead on. The temp gauge fluctuates between 190 and 210
deg. depending on how fast I'm traveling. Also the clerk said the smog
police would fail me if they saw I was running a cooler thermostat. Do
they care what temp my car runs at? If it matters I have a 1987
Wrangler YJ 258 ci Carter BBD, 5 speed manual. Any input is
appreciated.
Thanks,
Kevin
