2003 GMC Yukon 5.3 L Question

[Nyjetfan21]

I have A 2003 GMC yukon 5.3 L. I need to replace my radiator. I noticed it leaking and was losing alot of antifreeze. Any suggestions on where to get the radiator for a good price and any tutorial instructions would be helpful. My truck has duel climate control

You can watch you tube videos for the replacement process and I always recommend OE radiator replacement like this one: https://www.rockauto.com/en/moreinfo.php?pk=434905&cc=1415551&jsn=896 or this one depending on core size: https://www.rockauto.com/en/moreinfo.php?pk=1399643&cc=1415551&jsn=897

But on another thread about radiator replacement there is this option: https://www.tahoeyukonforum.com/threads/a-better-radiator.123326/

How do I know the core size of my radiator that needs to be replaced. Also do I need the radiator that calls for transmission and oil cool

 

[OR VietVet]

Then this is the one you want: https://www.rockauto.com/en/moreinfo.php?pk=7400712&cc=1415551&jsn=895

The core width should be right at 34" and that is measured between the tanks on the core itself.

If you choose to go with the Spectra radiator that has decent reviews, then this is it at Amazon: https://www.amazon.com/Spectra-Prem...PMYR9Z7DFWC&psc=1&refRID=GWX595AX5PMYR9Z7DFWC

If I had my choice I would go with the AC Delco line but if the 34" wide core and oil cooler capability is not available from AC Delco, then I would go with the Denso one.

Do you have the RPO codes of : KPN K5L KC4
