#517 of 596 So that's what it is... by metalibrarian Apr 30, 2009 (12:02 am)
No one ever tried to answer my question (#466, repeated in #477) about what the white translucent tank is under the battery of my 2004 4-cyl Camry. Looks just like a coolant recovery tank but that is over yonder on the passenger side. Dealer mechanic says that on a wet, rainy day it functions to collect moisture out of the air taken in by the vent on top of the engine so the water doesn't go into the cylinders.   Anybody agree/disagree with this finding? I've asked two service writers then this really young mechanic. I haven/'t asked at the parts counter yet, Delray, your car must have this.

Replying to: metalibrarian (Apr 30, 2009 12:02 am) I have the same tank in my 2008. I have no idea what it is and tried to trace the input lines but it was getting dark and I closed the hood. I'll look it over again this weekend to try and prove/disprove the water collection theory.

Replying to: metalibrarian (Apr 30, 2009 12:02 am) That makes no sense. The water vapor collected in an engine is burned off immediately--it doesn't "go into the engine".....or if your engine runs very cold (like marine engines) it combines with oil to form sludge. And besides all that, this white tank would look like the bottom of a cesspool in about 2 weeks if it was collecting water and oil vapor. And besides that, it would defeat the PCV system, which is designed to re-burn crankcase vapors.   But I'm curious, too, as to what it is. Could be vacuum reservoir?

#520 of 596 Mystery bottle by crazedcommuter May 01, 2009 (4:25 pm)
Replying to: Mr_Shiftright (May 01, 2009 8:17 am) I looked at the white jug again this afternoon and I'm not sure what its purpose is. I traced the air intake from the top of the grille where it decends at a 90' angle about 12" straight down into a U shape where it then rises 90' and connects to the filter box. At the very bottom of the U there is a female flange on the under side of the intake that fits into a male flange on the side of the white jug. I could see no other lines or any type of drain plug on the base of that jug. It is located directly under the battery on the driver's side. It's either is a water collection bottle or some type of a vacuum bottle. Replies to this message: 210delray (May 01, 2009 6:27 pm)

Replying to: crazedcommuter (May 01, 2009 4:25 pm) My Camrys both have this bottle. With no drain visible, it can't serve as a water collector. Could it be a resonator for the air intake? (Seems too large for this purpose.) I've never really given it much thought because it's largely hidden below the battery.
#522 of 596 Mystery by metalibrarian May 01, 2009 (8:13 pm)
Okay. we have good mystery on our hands. We all agree it's THERE. Now what exactly does ir DO? The air intake pipe is connected to it. Water? Sound? Replies to this message: kiawah (May 02, 2009 9:13 am) Mr_Shiftright (May 02, 2009 9:57 am)

Replying to: metalibrarian (May 01, 2009 8:13 pm) Allright, so after seeing a number of posts on this mystery bottle, I decide to go out and actually look at my 2007 LE 4 cylinder to see what you guys are talking about.   The plot thickens.......I have no mystery bottle under the battery. For that matter, I have no unexplained plastic mystery containers anywhere. Replies to this message: Mr_Shiftright (May 02, 2009 9:57 am)

Replying to: kiawah (May 02, 2009 9:13 am) Aha, the MIB got to your bottle!
#525 of 596 California by metalibrarian May 02, 2009 (11:21 am)
I'm the guy who raised the question...   I have a California edition of the 2004 Camry LE 4 cyl. Could the white tank be a California add-on to the antipollution system?   The tank in question is large, larger than the coolant recovery tank and seemingly made out of the same material but hidden away under the battery. I owned the car for years before paying any attention to it. There doesn't appear to be any liquid in it. If you have access to a Haynes book, it shows up in the photo of the engine compartment. But without further explanation.
