My diesel mechanic says that the radiator fins are rotting away, but no leaks.

Do I NEED to change it out now, or can I wait until there are cooling issues? I ran last summer with my scan gauge D showing very stable temps, and I just don't want to spend the $2k if it might be fine for another couple years. Just looking for opinions.

Do it ASAP while you can pick who does the work. If you try to get more miles out of it you’ll end up broke down in the middle of nowhere and paying too much for no telling who to fix it . You’ll be beggars instead of choosers.

Not to mention a ruined trip

I spent several weeks years ago, looking for a new radiator for my 2005 Monaco Diplomat. It paid off as I was getting prices in the $2K - $3K range. I forum member turned me onto a company that had bought a bunch of left over inventory when Monaco went out of business. I got the radiator, charge air cooler, trans cooler and fan shroud, all on a pallet, delivered for about $700.00.

My point, I would leisurely shop around for a unit, looking for a good deal and then install or get it installed when you can.

Dons advice is very sound.

If the fins are falling out the tubes can't be too far behind. How far is anyone's guess. I'm not saying to replace it tomorrow but I also wouldn't wait too long. Good luck.

Get a second opinion before you do anything.

We all know " Murphy " of law fame .
A blown out rad , will be ; wait for the tow truck , find the closest shop for repair and wait for them to find a replacement ....and they WILL NOT be shopping for the best price.

Degrease, clean, paint the radiator to preserve it. No pics so hard to provide good recommendations on it's condition.

Here's a thread I did when I had our radiator replaced. Hope this helps.

Good point! I will get some pics when I get a chance. I like the idea of cleaning it up and painting it. Thanks for the input.
