350i radiator

[jack350]

Hi
I've got an 84 350i with twin fans. anyone got any images showing the mounting of the radiator in the nose and mounting of the fans?

I'll try and take some photos(Mine is 1984 also) but in simplicity the twin fans are set in a frame which fixes top and bottom to the radiator into threaded holes on the body of the rad.
The radiator's weight is held by two fixings through the front of the engine bay into the nose area, and to stop it flapping too and fro there are two lugs on the bottom of the rad which sit into holes in the bottom of the front spoiler.

Simple and to the point.

i forgot how tight it is to try and photo the fixings, but the below pic is the where two flat head bolts fix through into the front nose section and screw into an "L" shaped bracket (with a nut welded to it)which is in turn fixed to the top of the rad/fan frame.

I have tried to photo the L bracket on top of the rad from underneath the car looking up

The top fixings hold the weight and the bottom is just held in place to stop any swaying by two lugs through the bottom of the front spoiler. The rad should have two metal pins on the bottom at each end, and then a plastic or rubber sleeve over to prevent damage to the fibre glass. I thnik I made my own by gluing some rubber hose on as i'd damaged the original plastic ones on a low kerb.

Hope that makes sense/helps. The only way to give a complete accurate pictorial would be to dismantle completely and remove rad !
Cheers

Also when you remove the front spoiler, I'll bet the fixing nuts/bolts are so rusted or seized they'll snap. Replace with stainless nylocks and stainless washers (see last photo) for only a couple of quid. It will be a breeze to undo in the future.

I think the sleeve performs a far more important job - to decouple vibrations going into the bottom of the radiator. I reckon vibrations are the radiator's nemesis especially in the wedge and cause the often-seen leaking at the corners over time.

Thanks for the pictures, really appreciate it
