What Is The Difference

[htp.bmw]

First of all I'd like to say sorry for the big pictures...

I just went to install my radiator into my 1990 325i convertible and found these things that are different.

My old engine had these screw holes in the front

[attachmentid=21678]

for this part of the cooling....

[attachmentid=21679]

But the new engine doesnt have these mount points..

[attachmentid=21680]

and where the second mount point is on my old engine there is this... what plugs in there?

[attachmentid=21681]

I'm totally just pulling this out of my ass... oil cooler? Or does an oil cooler run the oil through a radiator type thing? I'm not sure. Not trying to wast your time, honestly.

the oil cooler has 2 lines running out of it that go into the engine right next to the oil filter... and your not wasting my time at all... thanks for responding

I think you’re engine is newer than the other one, the older engine had a rubber hose instead of the metal on in pic2 but I can’t make out pic4

i can take another picture if you want, it was late at night and i know they didnt come out, if the older engine had a rubber hose then i have an older engine...

becaue the metal hose came off my new engine

After a day of research, I have found this..



my old engine coolant diagram

[attachmentid=21727]

My new engine Diagram, this has that extra port(thats what i think its called ) #10

[attachmentid=21717]

any ideas on how to make the first diagram work with the second one? the things that are the problems are how the lining gets to the reservoir and there is another port that wasnt on my old engine.....


thanks for your help... Casey

you bought an engine that is older then your car, obviously. looks like you got like an 87 or so engine? they used those old coolant resevoirs then.

you're going to need all the coolant lines off your original engine, since they changed alot about how coolant was routed (the resevoir was on passenger side on your "new" motor but it was on driver side on your original motor).

honestly, i'm not sure what all you'd have to swap going BACK in time as you did, but its going to be pretty much everything.
