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.

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. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
