Do your pullies and idlers as well. It's not a hard job and can be done with fairly basic hand tools. Read a DIY or two on the board to identify any tools you may need (torx bits most like). The hardest part of this IME is getting the new ET to sit securely on the bottom hoses. Everything else is a cake walk.

I'm not sure if I have the time & patience to do the work, so it may go to the shop.

It's disappointing that the rads have the failure rate that they do. It's not exactly high, but I've found at 100k miles is when you'll find a leak if you will end up developing one. I do not know exactly where the leaks are, but it's really lame since it's such an expensive part relative to the rest of the simple cooling system components.

Why does the radiator leak when the AC condenser is directly in front of the bumper and gets pelted by rocks, bugs, and debris every single day at high-speed but never leaks?

Because you've got a metal to plastic connection with a rubber gasket in between.
Condenser is all metal and built more solid.

Every 100K for a new rad for $150 is just a fact of life.

That sounds too cheap...but as long as it's an OE ET and therm(wahler) you should be fine. Radiator should be Behr.

Not sure what's in this kit...you have a link to it? I'm suspicious a little because of price...that's all.

A shop will cost you another $6-800 I'd guess, if not more.

You need about 4-5 hours...and you don't need too much patience...it's pretty straightforward if doing everything...and you've got back up here, you know!

I don't usually like BavAuto, but....

PS: looks like the link doesn't get you all the way to the kit. Go: "under hood", "cooling sys", then "radiators", second choice down is "Coolin Sys overhaul kit, standard Tranny" Pt#: "E46 Cool Manual".

Seems fine to me if you got stuck w/ a Nissens. I haven't tried them though. I know lots of japanese cars that used nissens replacement radiators w/ good results

Bear,

The kit looks good...don't know the ET brand, but Bavauto should have that part right...wahler therm, Behr radiator. Meyle is a good name for some things...not sure of wp, but I bet it's just fine.

I'm surprised...good price.

Don't forget the OE coolant and distilled.

Belts and pulleys would be easy to get to know if you're predisposed to do a little more...otherwise, they're easy enough to get to later.

Return belts in the same direction they came off (mark them if reusing).

I just changed my...Water pump
Water pump pulley
Idler pulley
Main belt
Ac belt

I noticed that my radiator is nissens and is stamped 2011 meaning I didn't have to change it ...but overall nissen doesn't seem like a bad brand/quality
