Cool

Greetings,

When I changed the radiator, I lost about 1 qt of tranny fluid. How can I put that back? Is that simple fo refill? Is there a dipstick to check the level? If there is one, I guess I can pour some through that hole !!

1995 525i E34 Automatic

Thanks

The fluid pours in through that hole where you check it.

I just don't know how you lost so much... I lost like 10 mL when we took my radiator out.

Sorry I didn't read your post correctly.

On my 1990 525i (M20 engine; yours is a M50) there is a tube type thing sticking up next to the firewall on the drivers side of the engine and you pour through there. I'll see if it's visible in one of the pictures of my engine that I have.

I believe it's this right here (hard to tell in the pic since there is so much stuff).

The engine is different, but I believe the 'dipstick' is in the same place since the trannies are the same.

mated with the m50 engine is usually a sealed tranny with no dipstick, you'll need to find the fill hole...

Maybe you could fill me in too... how do you lose tranny fluid when replacing a radiator??

Automatics have a hose going to the bottom of the radiator. It takes the fluid to the radiator to get it cooled (this is only for automatics though). So when you take the radiator out, you also have to take this hose off and then it leaks if you don't point it upwards or something.

I'm still having problems understanding (dense? maybe). The tranny fluid would have to go through separate cooling coils in the radiator...certainly can't mix with the regular coolant...so does that mean that the radiator is a two-in-one radiator? I know some cars have separate transmission coolers...but this is a first for me.

If I remember correctly the bottom (quarter maybe) is separate from the rest and only tranny fluid goes through it.

edit: By separate I mean just separate compartments, not physically separated.

nasty leak somewhere along the line. could be expensive. Only way I can see oil mixing is if its happening somewhere inside the engine itself.

Yup, if it looks like chocolate milk, you probably have a blown head gasket, between a coolant and an oil port. Thats the big downfall of an aluminum head, once you overheat them, they're toast....
