Agree with Tony on the thermostat being kept standard. for normal daily driving.
If your not careful lower engine temps can lead to richer mixtures.
Maybe not once engine warms in summer.
As computer and engine control is factory set and you properly cant adjust to suit new thermostat.
If you run cold thermostat in winter, bet enrichment is on the cards,even more so if you get wet, rain or creek crossing.
In winter you properly have interior heater going also adding to cooling the engine.
A rich mixture will cause engine to heat up and shorten engine life.
Not saying this is going to happen 100% for sure, But have seen these affects before especially in winter, Rich exhaust.
doing things like cleaning air-con condenser and radiator externally, for optimum air flow.
use de-mineralised water this raises boiling point of water to well over 100 deg mixed with proper coolant, not to mention less corrosion.
a proper designed catch can attached to water bleed screw can separate cavation/ bubbles from coolant, and slightly add to coolant volume.
A thermostat controlled oil cooler is another idea, also adds to volume.
larger air-con elec fan
Do you really need/use those spotties.
many things can be done to aid cooling.
