I replaced my radiator today followed by a bleed. I did not see any leaks at the time of bleeding. I then took a short 10-15 mins drive, after check under the car, unfortunately I did find a few drops of coolant on the left side, which makes me think it's coming from the lower hose.

At this point I think I have two options

1. Remove the fan on the radiator to inspect and try to re-adjust the clamp to make sure it's exactly at the same spot as it was originally.
2. Drain the coolant and replace both hoses and hope there would be no leaks this time.

Unfortunately the OEM hoses are pretty pricey (about $70) from Amazon. Any recommendations on after markets?

Do you guys have any suggestions?

 

Yes make sure the spring clamp in the same location or it could leak. Dayco hoses are very similar to OEM check Rockauto.

 

While I partially agree with your choice #1, I do not agree with #2.

When I say partially, the part I agree with is open and inspect ... really diagnose.

To help diagnose, loan a tool from auto box stores to pressurize the radiator. No fun to diagnose with a hot coolant. Stay at 80% of the marked pressure limit on the radiator cap. If there is a leak it will be evident within 50%.

If you have ripped the end of the hoses, then surely replace them.

And stay away from any hose made by URO. They tend to leak even when new.
