Overheating

[blindwOw]

Alright so I have an '87 325e and it overheated earlier today. I popped the hood to cool it down and steam was blowing out of a hose shown in the picture attached. I don't know which hose it is. Is it this one?

I did a radiator flush a few weeks ago. The PO had water in it so i went ahead and drained it, flushed it, and filled it with Peak 50/50 coolant. Would switching from water to 50/50 coolant have any affect on the hoses or cooling of the car? Would coolant wear the rubber seal on the radiator drain plug? Because after i cooled down my car i just filled it with distilled water and noticed it was just dripping from the drain plug under the radiator.

a hole in the hose. Ive had a leak on the same spot
Its time to buy a new one

Oh btw , welcome , i had a 87 325e once . look into the California threads , we have a HUGE Meat next month ;)

is the hose in the link the correct hose?

Yes it is. When your going to change it have some more coolant read or water. remember to bleed the system ( cap off the res and let it run for a good 15 mins or more. ) if you need help feel free to PMME , im in the Los Angeles area.

Alright cool thanks. I'm probably going to be doing this later today.
Also I've read that it is recommended to bleed it with the car on an incline, should i do that?

Yes, bleed it on an incline, and bleed it several times with heater on full blast.

Bleed it by:

1) Using ramps or a jack get the front of the car 1' or more higher than
the rear. That will make the radiator and bleed screw the highest point
on the engine and facilitate removal of air.

2) With the bleed screw open, add coolant until no more air comes out of
the bleed.

3) Leave the filler cap off, or at least loose, and set the heat for max
temp and fan speed. Leaving the cap loose will prevent air that's still
in the system from causing a "coolant fountain" once the engine heats
up. Start the engine and allow it to warm up to operating temp. As it
warms up occasionally crack the bleed screw to release any air and top
up the coolant as necessary.

4) Once the engine is at temp bring it up to 2000-2500 for a few seconds
several times. Then crack the bleed until no more air is released. At
this point the heater should be throwing lots of hot air, which
indicates that the heater core is filled with coolant. You may have to
repeat this a few times to get all the air out.

5) Drive the car a bit, allow it to cool back down, and recheck the
bleed for air. Over the next few days you may get very small amounts (a
few bubbles) of air out of the bleed screw.
