Hey guys,
I've got issues with my 2009 Aveo 5 LS. Any help with pinpointing the problem would be most appreciated. I've read through the forums a bit and I've seen similar issues to what I'm looking at now but none are quite the same from what I can tell.
So I'll just lay it down:
About a month ago the oil lamp and CEL come on. I took it to the Jiffylube and: 1. coolant is low (none in the overflow tank), 2. transmission fluid looks pretty dark.
They tell me that the tranny fluid might not be a problem, I figure I'll live with it. On my way to the store for coolant, car overheats, hood starts smoking. Turns out the lower rad hose was split. Through the course of replacing it, I notice that any coolant I put in comes out a light brownish colour.
Hose is now fixed, but the CEL doesn't turn off. Loss of power when accelerating, car bucks while I'm idling, and sometimes sputters when driving it. Thought it might be the head gasket but the oil level is staying high, and the oil is not sludgy.
It's had a problem in the past with the CEL staying on that just kind of went away, and I naively (mostly wishful thinking I guess) hoped that would be the case now. Not so. The other day I get another blown hose (a heater hose, the mechanic tells me) and white smoke is coming out of it. Took it to the shop, here's the rundown:
Guy says both O2 sensors are not functioning. He replaced the hose to check the engine block pressure and he thinks it's fine. There is definitely something dark getting into the coolant, maybe the transmission fluid?
He wants to replace both O2 sensors, and do a rad flush . +he already replaced the hose --> looking at $900ish after that, then we'll go from there.
Any thoughts/insight/advice would be very helpful.
Thank you
