Re: On my 96 deville i have a coolent leak coming from...
Hello: Check the coolant overflow tank, the hoses and the metal pipes the hoses attach to. If there is bubbling in the tank after driving the you may be low on coolant or have a blown head gasket problem.

I'm sorry I can't see your car. You need to ge a bright light then fill the system and with the light see if you can spot the source of the leak. I would be guessing without looking.I'm sorry I can't see your car. You need to ge a bright light then fill the system and with the light see if you can spot the source of the leak.

Well, if the coolant is leakimg from the HVAC drain, then you need a heater core, no matter what. You really have to jack it up and look, but I can give you a couple of pointers......
1. The water pump is leaking. That happens a lot. The coolant is leaking near the front of the car, near the center, but ever so slightly towards the drivers side. You need a special tool to replace it and I think gm has an updated cover and gasket.
2. The water pump housing is leaking. The gaskets that seal it to the block are made of plastic and deteriorate often. The coolant will be leaking at the center of the car, maybe up by the water pump, or back between the engine and transmission.
3. The heater hoses. I have only seen this 2 time, but the metal pipes corrode along the fire wall.
4. You could need a radiator. I have seen the side tanks leak a few times.....
Just A couple of places to look, but you have to get under and look....
check all your hoses run vehicle for awhile the inspect hose in this area. look for obvious things next check at the engine to see if a freeze plug is leaking then inspect you heater assembly the core may be leaking I'm leaning toward a hose or shut off valve
The AC condensation drain tube is also located on the passenger side fire-wall towards the bottom of the fire-wall, it is there to drain the condensation from the evaporator/core plenum so that it does not flood the passenger compartment floorboard with water and it can easily be viewed from under the vehicle, and if it is cool clear water that is leaking and not hot coolant then you have no problem and that is a normal condition when the AC is operating.
If it was a coolant leak the cooling system would be low on coolant, and the engine would run hot when the coolant gets low.
Hi , if you lift up your passenger side floor carpet and check underneath if there any coolant. If it`s dry you know the leak is in the engine bay ,if it`s wet could be either inside or outside of the firewall. In the engine bay check the hose clamps on both side of the hose if you can tight them or if one a those spring clamps try to reposition them. If you have hose clamp right at the firewall then you can easily change the hoses otherwise you have to access it from under or worst case behind the dash. Hope that helps.
The blower motor is on the passenger side of the front seats, pull the carpet back and you will see it there. Make sure it's not the little computer sitting right next to the blower instead of the blower. When you turn the temp down to 65 does the little orange colored AC button light up? If not, it's the climate control computer which is sitting next to the blower.
