Well im putting in a new engine/tranny in my car and i wanna either put a new radiator in or get my original re-cored, now which would be better? And also, whats better 1 large row or 3 rows? Lots of radiator sites are saying "wider single row to replace your factory 3 rows" id think 3 would be more efficient but im not very knowledgable when it comes to this.

Anyone??

Why change what has worked all these years?

Because it has numerous leaks already and i need to get it recored or get a new one, just need to know how many rows ours are and whats better 3 or one big one

well... you're trying to ditch thermal energy to the air... so the more surface area you can get the better.. go with 3 core.

Your stock radiator is a 3-core. Coolant, engine oil, and trans fluid. You'd have a hard time converting to a single.
