ginger Posted December 6, 2018 Report Share Posted December 6, 2018 I'm not saying it will make it run cooler than the t stat is set for unless your at a point that the motor would normally run at 210 instead of the 180 thermostat. It will regulate it better to maintain the 180 rather then the 210 it would run without by controlling the flow of the water better. Quote Link to comment Share on other sites More sharing options...

Again, a thermostat can only raise the heat, it doesn't lower it. A properly designed system, correct size radiator and correct flowing water pump will keep it running at 180 than 210. There is a reason they sell 160F and 190F thermostats for the same vehicle. Quote Link to comment Share on other sites More sharing options...
ginger Posted December 6, 2018 Report Share Posted December 6, 2018 it does lower it by opening up. and by slowiing the water down in the rad, and letting the fan or air moving through it cool it more, it does increase its ability to cool. You are correct it wont make it run any cooler than the t stat is made for, but it will increase cooling ability. Quote Link to comment Share on other sites More sharing options...

But more cores, thicker cores, more correct size and spaced fins. Quote Link to comment Share on other sites More sharing options...

You are correct it wont make it run any cooler than the t stat is made for, but it will increase cooling ability. Okay there seems to be some confusion about rad temp versus engine temp. Lets say the radiator is able to produce a 100 degree delta. As in keep the engine 100 degrees above ambient. So if ambient temps are 100 degrees the engine runs at 200 degrees. If ambient is 50 then engine temp is 150. A 180 degree thermostat will be open all the way when ambient temp is 80. If there is a 180 thermostat and the ambient temp is 100 then the engine temp is still going to be 200. Same as a non thermostat circuit. Below 80 ambient the thermostat will be partially closed, limiting flow of coolant. This limiting of flow reduces the amount of heat being removed from the cylinder by the radiator. This maintains cylinder temps at 180 and reduces the temperature delta of the radiator. Thus in this example. Anything above 80 ambient the engine and radiator temps are ambient plus 100 degrees. And anything under 80 the one with the thermostat is engine 180 and radiator anything under 180. If there is no thermostat then the radiator and engine arr both ambient plus 100.

registered user Posted December 7, 2018 Report Share Posted December 7, 2018 (edited) im not sure what the row size is but adding more or making the existing ones longer wouldnt be bad but this only works if theres not plastic body panels or frame tubes obstructing it. factory impeller probly doesnt move much water or at a high rate so thats the other area that could probly be greatly improved. maybe one of the after market impellers are worth a crap. reversing the water direction likely would do very little or nothing on these engine. it works on other engines but theyre completely different routing and entry/exit locations Edited December 7, 2018 by registered user Quote Link to comment Share on other sites More sharing options...
ZillaFreak Posted December 7, 2018 Report Share Posted December 7, 2018 Actually increase flow rate of the coolant can hinder's its ability to cool the head. Too fast and it doesn't have enough time to absorb heat form the cylinders or disburse heat in the radiator. As for reserving the flow, you have any actual data to back up your claim it wont work or you just guessing? Quote Link to comment Share on other sites More sharing options...
registered user Posted December 7, 2018 Report Share Posted December 7, 2018 why keep bugging claude, flopping the inlet/outlet hoses is easy enough if u want to see for yourself what happens. the water scheme in these engines is shit so i dont see why u think something magical will happen by reversing it. water takes the least path of resistamce which is across the top of the head. go ahead flop the hoses dude Quote Link to comment Share on other sites More sharing options...

You have no clue what Claude and myself have been talking about with this head. You ever think maybe there is a reason claude is running this CFD analysis and change the design of the head or are you just stupid? Run along now.
