Coolant Leak

[kdubs482]

So today I cam out and found a small puddle under my car. I was pissed thinking it was oil but after looking under the car its coolant. The coolant is leaking slowly but its dripping from the little nipple from the bottom of the rad from the driver side. I looked all over the rad and coudnt see any leaks on the faces of the rad and it seems dry near the corner where its leaking. Im stumped. New to this so any ideas what it could be?

could be something as simple as the drain isnt tight or one of the hoses is loose or has a crack, i'd chesk that first. Hopefully its nothing serious!

Before you rent a pressure tester, just run the car for a while,getting up to operating temp. Then shut it off, crawl underneath and start looking. As far as press. testing, go to local auto parts store, rent a coolant system press. tester. Replace your rad. cap with 1 in kit. Pump up coolant system to approx. 15lbs, watch gauge, see if it's bleeding down. If so, you have a leak somewhere.

before you go and pump it up check you rad cap first caps blow off at different psi
the cap will have the pressure it runs at and always never exeed the psi it tops out at
