Overheating, where to start
My prelude keeps over-heating, I have no idea where to start. It overheated so much that it busted one of the coolant hoses behind the block. I need it fix it asap. Any ideas?

no, smoking from under the hood, and I haven't noticed any leaking. It's heavily modified, boosted, etc.

Check:
Turn on AC and make sure fans are turning on.
Coolant levels
Leaks in the hoses or anywhere else (might be pinhole sized)
Thermostat (When your car gets to operating temp turn off the car and feel if bottom hose is cool)
Grounds (that's if you're not really overheating but it seems you are)
Bleed for air in the system through nipple by thermostat
(thanks Giant_Bean really worked for me)
Someone correct me if I'm wrong on any of this. It's just what I've gotten from reading around.

After that replace the cap, let a little pressure build up, and open the bleeder nipple and check for air.
