Decided to stop pu$$y-footing around, and yanked the old standard radiator outta my truck and installed a brand new '93.
For the uninformed, the early non-intercooled '91 rigs used a downflow 2-row core with the inlet/outlet pipes directly above/below each other, encouraging "short-cycling" of coolent in an already defficient cooling system.
I read back articles on the switch, and checked at my local radiator shop - and bought a brand new '93 crossflow radiator with 3-row core for $239. Other misc. stuff ran the total expense to a bit under $300. I cut off the water outlet on the thermostat housing, turned it around to the new direction needed, and welded it back on, and used 3/4 inch pipe caps for the mounting pockets down at the bottom of the radiator, and fabricated some very simple but effective top mounts. A new '93 radiator hose, a new fan shroud and a large copper 45% elbow to complete the needed angle from the thermostat housing, and it's done!
One minor glitch was the fact that apparently the fan is positioned differently in later Dodges, and the fan must be larger in diameter - so I had to fabricate a new back plate for the shroud from sheet stock and secure it to the shroud. It came out great, and with everything painted up, looks near stock!
NOW, all I need is some hot weather and a trip pulling our trailer up the Sierras to Pollock Pines to check it all out...
One question - seems SOME guys with the later '92-'93 Dodges have 4-row radiators, some 3-row? Wonder what circumstance causes the difference?
