Cadillac radiator
So far so good, great price is working fine even with an added in line electric water pump as some of you may know some northStarz overheat but my 1997 is still going with a reengineered cooling system.

We have a few different aftermarket companies who are based in either China or Taiwan build these radiators specifically for us, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle. If you have any further questions, please dont hesitate to ask.

On this radiator I know there is a entry for two transmition lines . What are the other two entries on the other side of the radiator for ? Or did I miss to plug something in there ??
Christian M January 13, 2018
Thanks for your question! The other fittings are for vehicles that use an engine oil cooler. If your vehicle doesnt have one, you can just leave them. Thank you!
Adam G January 13, 2018
The Other two openings are for if you have a trans cooler option on your vehicle. Thanks. Archie Brodey.
