Radiator re-core in process

Man, what a crappy week--- not just the rover, just one of those weeks. While I am checking and fixing some wiring on the rover waiting on parts, I decided to pull the radiator 'cause it had a small leak. Turns out I overpressurized my radiator at some point (they say my cap must have failed to relieve excess pressure to get pressure that high) and "bloated" the inlet side of the core. It's at the shop now getting an estimate. I had it recored previously many years ago at a shop no longer in existence and it was checked within the last 9 months with a clean bill of health.

Any advice on a recore? I have/had a 4-core in there from my last redo for more cooling, and I was going to ask for the same thing, but should I be asking for something in particular? I don't know crap about radiator technology. Any guesses on how much to expect? Thinking $400-600?

My radiator is at the shop getting recored at this very moment as well. I'm also getting a 4 core and although i was originally given an estimate of $340 I got a call back today stating that it's actually going to be $400. That's still about $300 less than the best price I could find for a new one.

Here is my understanding from my research before choosing to go this route. I discovered many people pointing out that aftermarket radiators aren't as "heavy duty" as factory recored ones. And when they talk about heavy duty they're really just talking about the material used on the radiator tanks (stainless vs aluminum). The core is almost always aluminum. Aluminum is lighter though, if that matters to you.

I did, however, ask to widen the core to the better fill the width of the radiator tanks/caps which is about 2-5/8" vs about 2". The idea is you're circulating more fluid, and more surface area for the fins to distribute the heat and thus provide better cooling.

Aside from that, there isn't much else to worry about.

Check with Jeffco Radiator (Used to be Arvada Radiator). It's on Sheridan around 56th. They've done my Series radiator and heater core. I've been pretty pleased.

Sereck in Denver just quoted me $575 for a 4-core... seems friggin pricey to me. Thanks for the heads up on Arvada Radiator...

Genuine is 630 at rn. Personally I would never recore again. The price is too close to getting a new genuine one.

I went the four core route and had issues. I put a new genuine three core in and it has never run cooler.

I went to a 4 core due to the 4.6 engine and off roading in the mountains of CO and Moab. The genuine wouldn't keep up on long up hills up here. I worry that a new genuine just wouldn't have the capacity for cooling. Maybe I'm mistaken on 4-core vs 3 core effectiveness, but it seemed to help a lot and the old 3 core was clean. But hey-- I fully admit to not knowing the ins/outs of radiators...

I'll keep my fingers crossed. Hopefully the 4core will work well for me.
