Starting steaming yesterday, coolant spraying under the hood.

This is most likely a simple cracked radiator but before I start dismantling it what would be the problem checklist you guys recommend?
And if it does turn out to be a radiator leak, I would think its best to replace it vs trying to fix. If so which brand of radiator from what seller would you think to buy from?

Heres a pic

 

2000 HONDA ACCORD 2.3L L4 Radiator | RockAuto

Denso is OEM

 

Thanks! Are there any other things that would be failing and cause this kind of leak? Before I just replaced it I was wondering if there were other things to check.
I didnt see any leaks coming from hoses or connections from a glance.

 

Buy one from AutoZone or oreillys.

 

Removing an old hose and reinstalling it afterwards can lead to a nasty surprise down the road. It is best to replace old hoses, even if they appear to be in good condition.

 

I replaced the upper and lower radiator hoses, radiator (denso) and the thermostat and seal.
What I'm seeing now is that the radiator fan is not turning on when Im driving around...unless the AC is on then both fans run.
I assume the temp sending unit is bad on the thermostat housing? Or could there be another issue?
