Seems like every season my 5.0 runs hot on initial start up. Last season I replaced the impeller and installed a 160 degree thermostat. Yesterday I started Old Skool for the first time this season and at spec 4800 RPM she went into the red just like last year.
Should I go to a 140 stat or stay with a 160? Last year she stayed just under the red at 4800 rpm with the 160. Still don't know why it needs changed again though.
