88 Prelude coolant leak
 

Just got the car, got her home and it started to get a little hot. Coolant is leaking from beneath the car. Just wondering what may have let loose. Engine is B20.

It is anyones guess as to what may be causing your coolant leak. You'll need to safely jack the vehicle up on stands and run the car while you pinpoint where the leak is coming from. Should not be difficult.

Could be an o-ring leak, cracked radiator, hole in hose(s), water pump gasket failure & so on. Check it out.

rad looks fine, and the top/bottom coolant hoses seem to be holding their own as they are dry. it appears as if it's coming from behind the engine toward the back or something to that matter. I put some coolant in and drove it around and it was fine, my guess is that it got really low and the pressure built up and forced it through a crack. O ring would be my guess, though im not sure how i'd pressurize the system to figure out the leak. Im pretty sure (hoping) it isnt the headgasket, as the car isnt billowing white smoke. it's my girlfriend's car so im sortof in charge of making sure it runs right. thanks for the suggestions. Im going to see about picking up a chiltons/haynes/bentley for it and trace down where the coolant belongs and check the seals.
