leaking antifreezemy car

[turbot2112]

car has been leaking antifreeze.every once in a while ill see a tiny puddle under the car. not in the front of the car though, towards the back of the motor. i crawled under the car and saw a spot of antifreeze on the lower control arm. i dont hink its the heater core. maybe a headgasket:? were is the most common palce to blow a headgasket on these cars. only reason im thinking headgasket is because i put the motor together myself . its got about 25,000 on it. anybody tia

I would rent a coolant pressure tester from the local auto parts store. And see where leak is originating from.

Might even be as simple as a hose or clamp!

I'd bet it's your heater control valve. If it's original, it should be leaking by now. These are still available at GM.

I think 1970gsx is right, check the heater control valve.

It's where the heater hoses go into the heater core up near the blower motor area.

Should have a vacuum line going to it and one heater hose into it and one out of it. Small S or 90 degree hose pieces off the hard water lines next to the throttle body.

Not hard to find.
