2004 Grand Prix GTP Leak?

Question

My last question said there was green liquid coming from my exhaust.. I checked my dexcool, and it is a rusty red color.. but the liquid coming from my exhaust is a flourescent green/yellow color.. any more tips?

Answer 1

Dexcool should be orange, you are probably due a radiator flush. that is only minor, that reddish color you are seeing in the radiator does concern me a bit for it might be that the transmission coolant tank on the radiator may have a leak on the inside allowing transmission fluid to get in the coolant, then again, it might be only the rust that has formed inside the radiatior. right now I would be more worried about the green/yellow liquid from the exhaust. That is a classic sign that you have a blown head gasket.

Answer 2

The gasket would not make touch at that factor, you practice rtv sealant to that region. it fairly is attainable that the coolant is leaking out without making touch with the oil there. It feels like the gasket desires to get replaced back. I incredibly have completed this technique on a three.a million and 3.8 v6, the two in Buicks. exciting difficulty is those have been older sequence 2 engines and a 2004 has the sequence 3 which replaced into no longer as services to those intake subject concerns. identity say take it decrease back to whoever did the fix and cause them to attentive to the situation. A closed thermostat won't draw any air into the equipment, and air in the equipment incredibly reduces tension in the equipment elevating the boiling factor. good success.

Answer 3

Like I said before, it's probably condensation, and the normal stuff that builds up. It may even be coming from a "weep hole" that they put in there intentionally, if it is the low point.

Again, does it stop leaking when everything is hot?

Also, again...green is weird, since by your own description you don't have green coolant, and there isn't anything else green that it could be. Green windshield washing fluid? I don't think so...
