what size radiator? 2 core or 4 core
What size radiator do I need on a 03 ram van 1500? Thanks in advance.
The reason I am asking is because I brought the van in to an A/C shop and the mech told me that my radiator is too small (2 core not 4 core) and I shouldn't have went with an electric fan. I know a lot of people have switched to electric fans so I am suspicious. Thing is, I am having some cooling issues, but I think they are related to the temp controller not turning the fan on at the right temp. and I also did not put the fan shroud back in.
Anyway, any help is appreciated.

The 2 row radiator is sufficient unless you live down in the southwest where temperatures can hit 125F outside, in which case a thicker radiator is a good idea. Also if you do heavy towing the thicker one is the better choice. Aside from those 2 conditions the larger radiator is just a waste of money.

Thanks for the quick reply. What do you consider "heavy towing"? Right now, the vehicle is just a 2nd ride for use on weekends at parks, camp, etc., but I do plan on towing maybe max 5k lbs boat. I believe the van with the 5.9l is rated for 10k. Also I am in Florida. Max here is upper 90 degrees.

Rsdata, unfortunately I already have the smaller rad or I would go with the largest version. I am just trying to determine if what I have is too small now. I replaced my rad a few months ago and upgraded to the electric fan based on what I read here. When I ordered the rad I didn't see options for different sizes.
I'm going to put my shroud back on and see if that helps. I also don't know why the temp controller isn't turning the fan on at a lower temp, but I'll call flex a lit and see what they say.

Sure but keep in mind the fan is only necessary below 35 MPH. Over that and the forward motion of the van forces more air through the radiator than even the mechanical fan can draw. So any fan related issues can only occur at idle or around town on the slow roads.

If your fan setup is not sealed tight against the radiator it likely will not pull enough air to keep it cool.
