Replacement radiator with tranny cooler...?

    Okay, during my engine swap, I discovered I have a small leak in my factory original radiator. I will probably run some stop leak through it first to see how that does, but I will eventually replace the radiator (not something to scrimp on in Texas heat).

    I began scanning JC Whitney and Summit this weekend without much luck. What have you guys done for replacement radiators when you have the tranny cooler in the middle? Will I have to loose the "integrated" tranny cooler and go with a separate one? Would it be more cost effective to do this anyway? If I also added a second tranny cooler at the same time, would it make sense to stack them?

    Thoughts?

    Just get a replacement radiator that has the tranny cooler in it. Just like what you have now.

    Was this price because of the CK5 discount? Did you have to order online?

    Thats a good price!

    I went to a local radiator shop when I needed a new radiator. They replaced my factory with a 3 core HD rad with the integral tranny cooler. I also added another aftermarket cooler inline with the cooler in the radiator. I run it into the aftermarket cooler first, then into the radiator second that way the fluid gets cooled, but when it is cool outside heats the tranny fluid to a decent operating temp.

    My Chevy isn't broken, its just out of gas.

    You know, now that you are on the hunt for a radiator, might I suggest trying to find a newer truck application that is aluminum? (I have to assume they went AL shortly after '87)

    Reason I mention this is that the aluminum radiators cool better, and on top of that, at least with the cars I deal with, a replacement aluminum radiator that isn't supposed to fit, but does, is CHEAPER than a "correct" copper brass.

    If I could find a site that listed the Modine catalog with the radiator dimesnions, I would try and find one that is close to the same size as our stock ones. I have a feeling one of the 81-87 "shorty" radiators would be EASY to replace with an AL car unit.

    Why insist on counting when the ring gear has the tooth counts stamped in?

    Call me at work Brian, I've got one on the shelf for around $130. It's the same one I put in mine after the fan clutch ate the last one.

    Definately get an external tranny cooler. If you regularly run in cold temperatures then using the integral radiator cooler in series with the external is a good idea but if your usually in warm temperatures then just run the external cooler. Heat is an automatics worst enemy! Just make sure you get a quality external cooler and not a cheap-o!

    I started with nothing and I still have most of that left! - <a target="_blank" href=http://www.echobit.com:81/k5/> Pictures</a>
