97 olds achieva 2.4

i'm losing coolant from outlet under vehicle where i assume the water drains when air conditioning is running.the coolant will drain out even when parked in driveway. i removed thermostat housing to replace thermostat, but there wasn't one. it only had an o-ring inside.i checked under vehicle to check if any lines were loose but didnt find any.i'm at my wits end. please help!:banghead:

Welcome to AF!!

It appears by your description that you have a leaking radiator core. Since the water is coming out of the area where the water comes from the AC, the heater core is in the same place and coolant would drain from there if the core was leaking.

i've checked for leaks in other areas such as inside passenger compartment and hoses but none found. i have a new radiator in vehicle.-----also i bought a new thermostat but it doesn't fit inside housing. when i removed housing there wasn't a thermostat.

The reason for the drain is to keep the water and coolant out of the car's interior. The heater core if it is leaking will flow the water out through the drain, so I would pull the panel under the dash and check the core especially if the coolant is still draining.

Sounds like a heater core to me. Same problem on my '97 Skylark, also a GM "N-Body" car. Replaced the core in less than an hour and the problem went away instantly.

i've checked for leaks in other areas such as inside passenger compartment and hoses but none found. i have a new radiator in vehicle.-----also i bought a new thermostat but it doesn't fit inside housing. when i removed housing there wasn't a thermostat.my 1995 acheiva v/6 sprung a leak in the same area. it was the inlet or outlet for the heater core. car rides so hard it ain,t no surprise. luckily they designed the drip pan to save your carpet. i,ve been driving for a few months with the heater core by-passed with no problem. in our south louisiana climate just open the drivers window a couple of inches. also be careful not to ever run that 4 cly hot. alot of discussuion about blown head gaskets. signed = jamesmetairie.
