    I am a proud owner of a 92' 325i 4-dr sedan. I will be replacing my original radiator soon and I would like to know how. I'm very handy with cars, but this is my first 1992 325i sedan ever.

    Also, I would like to know there are any gotchas that I should know. Lastly, where should I buy my next radiator from?

    Thank you in advance.

    Greetings from Minnesooohta.

    I was able to find great info on the Pelican site on "How To" replace the Radiator.

    Thanks anyway.

    There are generally two choices for a radiator replacement, OEM Behr and an aftermarket Nissens.

    I have used a Nissens on an E30 with good results and used a Behr on my E36.

    Bimmerworld.com sells both brands for good prices.

    While you are doing the radiator I also recommend replacing the expansion tank and cap as well as the thermostat, main hoses and water pump (if not already done previously).

    Also don't forget to drain the coolant from the block by removing the drain plug located below the exhaust manifolds on the side of the block. This has an aluminum crush washer that can be reused if carefully removed and not over-tightened upon re-installation.

    Good Luck!

    Pelican Tech Articles

    I was going to suggest the Pelican Tech pages... I have not replaced our E36 radiator yet, but some of the other maintenance we have done has been made much easier with the aid from this site. Also, if you have not introduced yourself to Mike Miller yet. he is an invaluable resource for all things BMW.

    a few other suggestions......

    i echo the mike miller comment, if you plan on keeping the car awhile, get his recommended maintenance schedule; it's great!!

    i have two books in the garage anytime i'm working on my 3 series; first, the Bentley service manual, and second, 101 Projects. 101 Projects is available through Pelican Parts and serves as an excellent companion and sometimes cliff notes to the Bentley service manual.

    the pelican parts tech pages have some great writeups, as do a few online sources such as bimmerdiy and various forums.
