I have this Kia Sorento 2009 2.5L EX VGT

Last month, I had overheating problems. Turns out the repaired radiator had leaks already. It's still the original aluminum radiator with bronze upper tank. It was repaired 2 years ago.

I had it repaired for 700 pesos. Installed it back but still, it had leaks. I had it repaired again for 700. After a week, it still had leaks on different parts of the tank. The seams are leaking. Frustrated, I went to a better radiator repair shop and had it repaired for 1500 with overhaul. But this time, I asked for a warranty. The staff gave me one month warranty.

Upon checking kanina, it had a minor leak again, probably a pinhole leak somewhere in the radiator core (sa taas banda were the fins and the tank meet). I'm planning to bring it again to the shop na nag provide sa akin ng warranty.

If this will still leak, I have 4 options.

Option A:

Look for an aftermarket/replacement radiator. I live in Davao City. I scoured every parts store locally and they do not have one for my unit. I'v heard of Evercool brand but they don't have one also for my unit so they need a sample to make one. Since I'm from Davao City, I don't have the time to ship my radiator to Manila, and the cost will be huge.

Option B:

Go to CASA. I called and their estimate is 27k for a brand new original radiator. I'm willing to spend up to 30,000. Since this is original, I can be assured of a problem free radiator. Downside is, if the part is available in Manila warehouse, waiting time will be maybe a week. But if the radiator will be ordered from Korea, it will be 45 days.

Option C:

Fabricate locally. I found a radiator shop that will fabricate a new radiator for me for 12,000 pesos. I think it's very expensive for a fabricated radiator. I'm better off buying a replacement radiator instead, but the issues on Option A exist.

Option D:

Recore. I do not know if this is the same with fabricate. From what I read, a recore is having a new radiator core but the top and bottom tanks will be recycled/reused. I have no idea how much this costs.

So what are your thoughts? Which option is the best for me?
