Coolant Leak + Intermittant PO128
Hopefully this is something simple like a failing hose or something...but here goes:
About a month or so ago I got a SES light with code PO128 (engine wasn't reaching proper operating temps). AutoZone said it could be a bad thermostat, low coolant, and a number of relatively cheap things. So I check my coolant level, and the coolant in the overflow was low. So I buy some coolant and before I even get home to put it in, the SES light goes off on it'* own. Upon researching PO128, I found that if the vehicle completes 3 successful driving cycles without throwing the PO128 code, the SES light goes out. Apparently thats what happened in this case.
So last week, I was driving about an hour away, and the SES light comes on again en route. PO128 was the culprit once again. I drive with it on for another day, and the light goes off again. So I start thinking well...if it'* not getting up to operating temps, maybe I should let it warm up before driving it...it is cold as hell right now.
Well...yesterday I noticed leaking coolant in the driveway, and smelled it as well. It was NOT leaking until the past couple of days...atleast no at the volume that it is now. It is literally POURING out of the left side of the engine compartment, I can't really tell where though. But it is a nice dripping stream. Seems to only be happening while the car is running though, and stops shortly after I turn it off. Any ideas? I currently don't have an SES light, but I'm sure its a matter of time.
