225 running a bit warm!!!

Bill, I think (but don't know for sure) that the implication was that the water would travel too fast through the radiator to take advantage of its cooling potential if the thermostat is removed. This also means that the water going through the block would not have time to pick up all the heat. So when it gets to the radiator it would be a little cooler. However the water would then return to the radiator sooner, and then back to the block sooner. With an unregulated system like this it would seek its own level and the temperature would reach a certain point based upon how the engine was being opperated. In general this temp would be a little low (taking into account the engineering of the system which might see some extreme conditions having a built in safety margin) for the engine to operate properly. The comment was made that the thermostat keeps the engine up to operating temps (also the heater functions better), this is true. What you had to say is also true. Getting into the physics of heat transfer and fluid flow is getting out of the league of most people. The engineering should already have taken take into account friction and heat build up from fluid flow, cavitation, pressure, volume, material composition, fluid composition, ambient temps, and a myriad of other variables. The solution is to figure out which component isn't serving its purpose and repairing or replacing it. It is spring. Maybe there are bugs in the radiator.
