cross flow vs. up and down-aluminum radiators

Their is a difference between the up&down and the cross flow rads.The difference is the distance the coolant travels!If a rad support is wider than it is tall,you go with a cross flow,due to the longer distance the coolant will be in the rad cores.The up and down system normally is with a very square rad and the surface area is basically sqaure either side to side or up and down.A alley rad will disapaite heat easier and faster than a copper/metal rad that is for sure.But its going to be the core tube size and the amount of tubes thats going to determine the cooling capability of your system.Now you choose if you can do a mod to the rad support,what is the total area side to side and up and down you have to work with,and how thick of a rad can be installed,as some cars/trucks have limited space?The hose location is a simple deal,with some mods to the hoses and a couple of steel tubing extensions and you have back your origanal rad hoses with a bit extra from your local auto parts.If you install, a alley rad,and you drop your temp a good 20-30 pionts,install a HOTTER thermostat,Yes thats right,a hotter thermostat,WHY,as you have now a very good running system and can rid your system of heat,by running a 185 degree themostat,over a 165,you can keep the coolant in the rad longer for more cooling and keep the motor temp at a better operating temp than before and be more consistant than before with a temp that goes all over the board,Mrmopartech
