Redline Water Wetter or Royal Purple Ice might lower the temps. They're
intended for use with plain water in race vehicles so that when there's a
coolant leak they don't make the track or drag strip slick.
Their effectiveness is decreased in a normal 50/50 antifreeze/water mix but
they still lower the temp of an engine quite a bit, or keep one with a tendency
to overheat on 50/50 from overheating.
After changing the engine in my sister's 1995 Buick Century. I had the ECM chip
reprogrammed to lower the fan ON temps by 15F, along with disabling the 112MPH
limit and tweaking the fuel curves. Swapped the 195F thermostat for a 180F and
it still wanted to run extra hot. A bottle of Water Wetter fixed that.
It overheated because the "smart" people at GM thought it was a good idea to
run a 16 PSI system at 195F, the instant the radiator cap weakens, thar she blows, or
it'll blow a head gasket. They also decided the piston to cylinder clearance had to be
extra snug. So when that engine overheats the pistons leave aluminum on the cylinder
walls, the piston skits bend inwards a bit too. That makes them clatter, which sets off
the knock sensor. That makes the ECU futz with the timing and fuel in such a way that
*makes it run even hotter*. For 1996 GM applied a special coating the the skirts of
pistons 5 and 6, then for 1997+ all six got the coating. Just couldn't admit that running
it so hot was wrong, along with other things they did to it, without going far enough to
make it able to handle the higher pressure it needed tow work properly at 195F.
Anyway, the lower temp thermostat and ECU changes made it able to get out of
it's own way and overall MPG improved a bit, likely due to less time being
spent in accelerating up to speed since the engine could make more power and do
it faster.

Okay. I spent the afternoon putting a fresh bob in the G0704 kit,
then tried to bore 1/4" holes lengthwise thru 5.5" of 1/2" alu, with a
3" drill hog bit. That means I was drilling 3" deep from both ends
with the holes meeting in the middle. 4 such holes all the way thru, 3
slightly missed each other but a 7mm reamer from both ends of the
holes fixed that right up. Now I need to hit the store and get a
small bottle of lysol for the kool mist sitting in the coke bottle,
and long johns for for some fish. Somewhere I missed lunch and its
catching up with me.
Since I have another, better motor coming for the 6040 I am tempted
to put about 4 oz in the water tank, just for S & G. If it doesn't
total the water pump, I haven't lost anything.
But beware, the lysol in a spray pump bottle from the grocery store is
not the stinky stuff we all remember from our childhood, its now a soap,
putting a head on the water and virtually odorless. I first put about 3
squirts in the mister bottle, and about 20 in the water tank. It been
running at 4g's for about 8 hours And its likely well north of the lcd
thermometers top of 40C. And if it doesn't do squat I won't be
surprised, it isn't the real stuff, nothing like the lysol I remember.
The 'new' lysol is a quat

rather than the classic creosote based smelly stuff.
It should work quite well to suppress biological activity.
