1MZ-FE photo - what is this?

[lgrouper03]

Lately I have been trying to identify the source of an inconsistent leak which sometimes leaves 2-3 drops of coolant on the garage floor. From my attempts to trace the leak, I believe it might be coming from this "plate" on the cylinder head. Does anyone know what this is? Is there coolant behind it? Just to ground you, the black body at the bottom right hand corner of the picture is the oil filter. The camera is sitting on top of one of the cooling fan motors, alternator is to the left, exhaust manifold up above. This is a 1MZ-FE V6 in a 1995 Camry. Thanks in advance.

got it :P its a water seal

look at the part circled in red and follow the dotted line

the p/n is 11492-20010
if you goto http://www.toyotapartszone.com/Page_...ponentsIndex=5

scroll down on the far left hand coloum to 11492C and you'll see the description
PLATE, WATER SEAL

if you have ever used toyotapartszone, for future reference idk why they ** out the first two digits of the p/n but the first two digits of the PNC is the first two ** in the p/n
i.e **492-50010 = 11492-50010
Replaced by: **492-20010 = 11492-20010
Hope this helps

OH: and incase you need these to save you some time the two studs u need if your thinking about replacing that the p/n is 90080-12002 and the two nuts 90179-08153
90080-12002 x 2 (Studs)
90179-08153 x 2 (Nuts)
11492-20010 x 1 (Plate)

In case you're wondering why on earth Toyota would put a hole in the block and then plug it with a cheesy plate; For those living in a very cold climate (think Minnesota or Canada, with -30F winter temperatures), that's a place to install a block heater. I figure since you're in Texas, you may not have ever heard of those?

I actually used to live in Grand Forks, North Dakota. We had a 89 Corolla All-Trac SR5 Station wagon 5-speed with a engine block heater :P

LOL!!... Small world. I grew up near Fargo, where block heaters were considered standard equipment!

lol yea, I was actually born in Omaha on Offut AFB, my parents are retired officers in the Air Force about a year or so after I was born in 87 we moved to Grand Forks for about 2 years (they were stationed to Grand Forks AFB) :P we were there from about 89-91ish?

After speaking with the dealer about this, it looks like there is no gasket in this location - just a bead of Toyota FIPG sealant. If that's the case, I can just remove the plate, clean up, and re-seal. Does anybody out there know different? Thanks.

sounds like you're spot on. just make sure both surface areas are clean and free of debris.

Here's what Toyota says to do. This is for a 2000 1MZ-FE so YMMV.

God bless ToyotaNation! I found a coolant leak in my 96 Camry coming from exactly the same plate and now I know what to do. Thanks for the info, guys!
