I've got some coolant leaks in my 2005 LS V6. Not sure if the systems are very different, but most of the coolant threads I've read here focus on the V8.
The car overheated a while back, and the coolant pretty much drained itself in the street. This happened shortly after a rear end collision that put a lot of force onto the passenger side exhaust pipe, not sure if that is related. I replaced the thermostat and used a leave-in stop-leak as a temporary solution to keep it running. I don't want to put much money into the car, as it's not my daily driver. It runs fine now, but the coolant leaks seem to be increasing based on the level in the degas.
3 leaks that I can see:
1) Leak below intake manifold that puddles (on lower manifold?) when not in use, and then burns off. I thought this was oil before, but given the coolant issues I'm thinking maybe it's just more coolant. I'll try to attach pictures of this one.
2) Leak dripping from exhaust
This is much slower now, but was pretty bad before the stop-leak. There was an O-ring mentioned in another thread that could be the problem here. If so, where is it on a V6 and what part(s) do I need to replace?
3) Recently an occasional small straight line of coolant can be seen below the driver's side firewall. About 8 inches long, seems to be directly below the degas bottle. Not sure if this is from the bottle itself or a hose, etc.
Any thoughts on how to fix this, preferably without replacing the entire cooling system? I'm hoping to get some insight before tearing the thing apart and chasing my tail.
