I don't think it's worth it. Leaving the switch on hot helps a bit to cool down the coolant but not that much imho.

Don't worry pal!!!

If the coolant stays cool reving close to 7,000 rpm at our temperatures
down here then there is no problem for you!!!

Yep, more important is to warm up the engine properly (no revs above 3.000 until oil temperature has reached 90°) and to cool down after a "hot" run. Leave the engine running then for a few minutes before you turn it off :)

I used to leave mine on hot too but with these temps it's pretty hard to. I still do in the mornings.

One benefit of having the heater on is that when it starts to blow cold you know your coolant is out/low and you can stop before car overheats and does any more damage to engine. I know this from first hand experience, but didn't know at the time that my HG was about to go so carried on driving until car cut out and wouldn't re-start....

Relax! If the engines too hot, the fan'll come on! To be honest, unless you pootle about in slow moving traffic, the fan won't ever come on anyway. Bear in mind that engines aren't particularly bothered by rises in ambient temperatures, they'll regulate their temperature themselves.

I tried leaving mine on hot last summer in the hope that it might help engine cooling, but I couldn't live with the cockpit temps. Now I just use the heater as intended and at this time of year it is always blowing cold air.
