Did you replace your cap?

Can you see coolant collecting on the top seams of the ET? or is it strictly from the bottom?

Fan switch, or lower radiator hose will leak on the left side of the car.

Right side can be many things, and either way, you will need to pull the splash shield off, and inspect while engine is cold.

I replaced my cooling system 12k miles ago, (all but hard pipe, and I forgot a new ET cap)
Below is an example of my bad cap vs. new cap on the left:

Notice the lip is sheared, so it won't seal properly.

Also the O-rings have a tendency to flatten out on a bad cap. they're $12 and good to replace. i remember car and driver's test of a brand new E46 back in 2001 had to visit the dealer due to a bad cap (when new!) so it can happen even when new.

Yep, the bad one on the right O ring had flattened completely, and looked like a black dry rotted rubber band. I attempted to seal it temporarily with a random O ring, that I had in the trunk; just to get me to Bavarian Auto.

Thank you guys, after going to my connect we fully inspected it and even used an air pressure tool. The hoses, tank, radiator showed no leaks. Turns out the ET cap was pretty depleted, so we changed out all the rings and seal. So far so good. Ill keep you guys posted.

Wow. Some people man. Did you at least get a note?

I put my mud flaps back on because I hate washing the fenders every two days. And filled up with gas on the way to school.

I put a brand new entire cooling system (radiator, expansion tank, thermostat, upper/lower hoses, and water pump) in and just upgraded to the electric fan in my auto.

Nice...did you do a proper bleed? Don't forget a new expansion tank cap too!

Yes! I should have included that the cap is new also, you don't think I wouldn't replace the cheapest part do ya?

Oh and bleeding was kind of a PITA but no more low coolant light or overheating issues. And my heater works now!

Sold it and bought an E91 wagon. It was our 4th E46 and it was a nice ride.

Nope.

No note. Had campus police come out and take a record of it. Thankfully, its not scratched or dented, so it'll buff out

Especially with manual shifts! There is only one for sale right now on Autotrader and eBay and craigslist (NYC metro area) and it is in Rochester, NY. Who wants to drive up to Rochester in the middle of the winter to look at cars? I am glad I found mine in Philly.
