coolant leaking

i turned on my car and the add coolant light came on but no buzzing so i figured it was a faulty sensor. then he light wouldnt go away intermittently like it used to so i checked the resovoir and it was bone dry and then i opened the radiator cap and the level was low that i can see the fins and a little top layer of coolant mix. i looked under the car and there was a puddle of liquid..

a few days had passed and now there is a dryer puddle and no fluid i can see at all in the radiator.. crap somebody help me please

pics:





i know there was a tiny leak on the coolant seals in my carb but i thought it went away.. i guess its back but now this new leak i found has no visual detection. it must be in between the housings on the bottom by the oil pan. rebuild time? or drive around until it blows. but then i have to tow it to a shop to rebuild... but im kinda short on cash.. god.. i have problems =[ should i try some radiator stop leak stuff?

The leak is most likely between the intake manifold and housings, the manifold has a water jacket fed from the block. I would recomend checking them. Also have a coolant prssure test performed.

i understand there might be a leak coming from the intake manifold but i look down the passenger side of the engine and theres no traces of fluid rolling down there or rolling down the back side either.. its just accumulating in the bottom of the oil pan... thats why i figured it was leaking on the bottom of the engine rather than the top where the intake manifold is. thanks for your input tho.

Check your water pump, pump housing and thermostat housing. Also check the bottom of the radiator. Radiator looks like it could use a good cleaning/flush.

i wouldnt expect it to be the front kuz the little drops of coolant is coming from the rear of the oil pan but i would get it checked out and if i cant diagnose it myself im thinking of taking it to a rotary shop. too bad nobody lives near me to help me out

if u put coolant in it or water(wichever) pressure test it at about 15lbs and look everywhere u should find the leak, also if the needle drops on the tester(which it will) then u know u have a leak.

I had somewhat a similar leak and I found that the hose going from the oil cooler (pine cone) into the engine was badly worn and was actively dripping. That looks somewhat like your area, so try checking there.
