Radiator question

[fastivaca]

I'm running a B6 with header, mild ported and polished head, and custom intake. I have factory A/C and my current radiator is a stock Festiva single core.

We are heading out on another road trip that will take us across Nevada to the Grand Canyon and through Utah. We're anticipating some pretty hot weather especially when we're around the Grand Canyon and Zion.

I have a Festiva dual core (from an automatic trasmission car) in the garage. Would it be worth swapping this radiator in before we go?

Thanks

Ian

Its probably more important to thoroughly trip check everything...leaks
seeps, bearings, battery, cables..tires

However you mention high altitude , hot weather and bigger engine and
you want us to say go for it!!? Either with or without the "new" radiator
find the longest steepest pass around and test it before you go..then find
another to idle up slow to see if the fans can keep it cool. Have a great trip!

I would say yes, as long as the new radiator is in good condition.

^ +1 bigger is better in this case.

It is very little work to swap the rad, and it is cheap insurance against a road side stop in oppressive heat. It seems like a good idea to do the swap. You might think about having it tested first, but that costs about half the proce of a new rad, unless you have a good friend in the business.

Might also wire a rocker switch into the ground wire that goes to the temp switch for the fan (the one you disconnect to test fan operation. That way, you can manually over-ride the temp sensor and turn the fan on whenever and for however long you want. It might be nice to get a head start on it, if the temp guage starts to climb.

I agree, if it's not new, I would have it pressure checked first. If I swapped radiators and the new one ended up being bad, causing us to break down in the middle of no where.............my wife would never let me hear the end of it.
