So I may have to be buying a new radiator and was wondering if anyone has a good place and a good upgrade they have done in theirs. It a 91 laredo 4.0 4x4 with fac. tow package. Should I go with an aluminum or all copper? I know a min 2 row just not sure on the rest. Thanks guys

 

OE is the modern style 1 row aluminum/plastic. Copper/brass is old school.....don't think any copper/brass rads have been factory installed for 20+ years. Google and search this forum for all kinds of radiator info both aluminum/plastic and/or copper/brass. Don't be fooled by marketing that says "multiple rows" thinking they're multiple times thicker core than the stock OE 1.25" thick core.
