need a radiator 1990 k5 silverado

[nascarnutz]

what is my best choice for a radiator? i live in charleston S.C. so it gets pretty hot in the summer but not like out west. 98 degrees here in july. im wondering 1 row 2 row or 3 row. dont really tow a lot but i do run the ac constantly. autozone has all 3 but should i go for the overkill? is it worth it? what is stock in a 1990 silverado blazer? how would i find out? sorry lots of questions kinda of a newbie. only had the truck 2 weeks and it runs great but a pinhole leak in rad is gotta be fixed and i would rather go with new at 18 years old.thanks

It's really going to depend on the upper mount you current have. The wider the radiator gets (more rows) the upper mount changes along with the lower rubber cushions. I'm pretty sure though that you can get the 3 row in the same mount you currently have (my 89 blazer has a 3 row with factory mounts). I would go with the 3 row and be done with it.

A nice two-row with large piping will cool just as well as a three-row, sometimes better.

That said, I've ordered several CSF 3-row radiator from www.radiatorbarn.com and have been happy with all of them.
