Anybody Recognize This Part??

[ovsa]

I have a 1998 catera. I recently noticed a small oil leak under the front driver's side . When i looked under the vehicle i saw the [COLOR=blue! important][COLOR=blue! important]oil [COLOR=blue! important]leak[/color][/color][/color] was coming from a component (cylindercal, size of a tin can) located on the bottom driver's side of the [COLOR=blue! important][COLOR=blue! important]radiator[/color][/color]. It has a couple of hoses going into the top (looks like [COLOR=blue! important][COLOR=blue! important]coolant[/color][/color] hoses) as well as a red plastic knurled knob into the side of it. It sits right on top of part of the [COLOR=blue! important][COLOR=blue! important]suspension[/color][/color] frame( sorry i don't know the exact name)

I've looked at manuals and on-line but can't seem to ID the part. Any help out there and any idea how to repair the leak?

Thanks in advance

the thing with the red knob in that photo is the drain for the coolant

o.k. thanks, i still don't get why there is an oil leak coming from it, but i will have a closer look at it when i get back home.

Thanks for your help

i had a friend put a white kitchen plate under the drip and it is definetly oil. A red / pinkish oil. I'm thinking transmission or power steering fluid. Is there a tranny oil cooler attached to the radiator and can that cylinder componet have anything to do with it?
Thanks
