Do NOT buy radiator CSF3632!

[NightmaresInETorx]

Hi everyone. I had problems for a couple months with my car not blowing any heat and engine not getting up to temp. I did the usual tests, replaced thermostat, etc. And then found out that it had to do with my recently installed radiator, a CSF3632. Keep in mind this only applies to the early model years when it had a bottom hose on the passenger side going into the thermostat. What happened is the trans cooler cell in the bottom wasnt sealed properly and allowing coolant to bypass the thermostat. I ordered a replacement thinking it was only a problem on this one unit, it came faulty as well, and then a Spectra that was a re-boxed CSF with the same problems. This caused me a lot of grief dealing with CSF (who were no help in even acknowledging the problem) and a parts supplier and ended up costing me several shipping fees. I'm leaving keywords here so maybe someone who's looking for a radiator or diagnosing can use the advice.
