Has anyone on here that originally had a single row radiator replace the single row with a double row radiator? My radiator just started leaking from the passenger side tank, the plastic has a hairline crack in it and I don't want to repair it so I'm going to replace it, and the difference in price between a single row or double row is only 10$ so if anyone can confirm it will fit I'd rather install the double row just for extra cooling capacity for towing etc.
My main worry is will it fit in the rad support I have without contacting the radiator fan? and will I need to trim the fan shroud or anything?
Ok thanks john, I figured it should fit since the single row in there now already has end tanks that would fit a second row the main thing I wasn't sure about was the fan shroud clearing everything so I figured I would double check before I jumped head long into it.
See that was exactly my concern, I knew just looking at it visually the fan shroud looked like it would be tight as is. On a V8 it probly wouldn't be any different, but since the 4.9 is so long I think i'll need to find that shorter fan shroud.
Actually I just went and checked and I already have the slimmer fan shroud in those pictures in the link he put up. My current radiator actually just has some lean built into it at the connecting tabs where it bolts to the cross rail at the top, so as long as the double row replacement just has connecting tabs that come straight off and don't make it lean back any I should have plenty of room.

I just went out to check my truck and it has the single core radiator with the thicker shroud and a 7 blade fan.
Some trucks came with a 5 blade fan and others with a 7 blade but I don't know if this would cause any clearance issues with the 2 core radiator.
Don't do it unless you live in the deep south, the 4.9 doesn't generate a lot of heat so you can end up with a situation where the truck never gets warm enough to enter closed loop in winter.

Just for reference in case anyone comes in here looking for answers to the same question I had the above statement is not true. Changing the fluid capacity of your radiator by swapping a single row for a double row has no effect on the engine reaching operating temperature and therefore entering closed loop. Your thermostat if functioning properly will not open until it reaches the preset 195 degrees. The entire purpose of this thermostat is that it keeps the coolant from entering the radiator until that preset temp. is achieved basically eliminating the radiator from the cooling system until operating temp. is reached. So no truck with a properly functioning thermostat will ever have an issue reaching and keeping operating temp. no matter how large a radiator you put in it.
Also, I'm going to try the double row radiator swap when I get the time and also once I get paid again since I'm short on cash from throwing money at all the other things the truck needed. So I will try to take some pictures of the swap when it finally happens, document any issues I come across and any solutions to those issues if any exist lol.

+1, and I don't know about OBD I but my 96 (OBD II) truck will go into closed loop whether the engine coolant is fully warmed up or not. Think I read somewhere it will only wait so long before it times out waiting for coolant temp and just goes into CL anyway, and/or waits for o2 sensors to warm up. I have 180* thermostat too, runs just fine.
I was a double A fully ford certified ford mechanic at a dealership in Springfield PA by the name of Springfield ford for 5 years and worked on plenty of cooling systems doing upgrades for towing etc on gas and diesel engines. So, Yes I do have first hand professional experience in a cold weather climate with the backing of ford motor company credentials. Lol
Wanna be a smart *** anymore? Lol
