New coolant problem...
So... this JUST happened to me (in the process of getting my car towed home)... my coolant alarm went off for "low coolant" right after i noticed steam coming out of the kidney grills... i pulled over immediately to find coolant RUSHING out of the bottom; pretty much directly where the adjustment screw is ... i'm thinking the 'Radiator Coolant Flow Adjustment Screw' came out... i'm ordering a new one right now and changing up the type of coolant i used... but my question is... why is it called an "Adjustment Screw"?
And if this is the case... it looks like i have some editing to do in my DIY video... Last edited by N0OS3; 11-07-2012 at 12:56 AM.. |

It's been a while, but I remember there was two parts to it. The outer shell of it was like a bolt and the inner was a phillips head type. I didn't think too hard when I went to drain the coolant and tried turning the bolt portion....and I heard a crack, like plastic breaking. But all seemed fine as it still seemed to stay on. Then I unscrewed it via the screw head inner portion to drain it. Put everything back together and it was fine for maybe 3 days. Eventually though, it fell out and I had to do roadside maintenance. Luckily I carry safety wire and I was able to safety wire that drain plug on, refill with water and continue driving till I got a new plug. If you tried turning the bolt outer portion, most likely you broke the clips and at that point that plug was just staying on because of friction.....which is not going to work for long.

I see... well, turns out it was in fact the plug that fell out... i ordered a new one already and picked up some fresh coolant.
So, now that you hooked up safety wire to it, is that your final solution? I'm trying not to go about this in any ghetto fashion but i want to be sure the drain plug i'm replacing it with will stay in... I don't recall breaking any plastic clips when i turned it when taking it off. |

If you look at the pic, it's slotted on and only turns clockwise. I tried to take it out (counterclockwise) and snapped the clip. Friction was enough that I thought it was still on. It is very possible that when you tightened it with a screwdriver, you also turned the outer portion enough that the clips lined up with the slot and eventually pressure pushed it out. Examine your old one, it might be fine. Mine was diffidently broken. The safety wire worked great to make sure the old one didn't fall out, but after getting the replacement, of course I did not use safety wire for it again. Although for a few days after that I kept checking to make sure I wasn't dripping any coolant there and also carried around a gallon of distilled water. But it hasn't leaked again and it's been several thousands of miles since.

I forget, it might turn counterclockwise to the point where the clip hits a stop, lining up with the slot and then you can pull it out. When I broke it, I am sure I just cranked on it without paying any attention. Maybe when the OP puts the new part in, he can clear it up.

I've confirmed that i broke off the tabs as shown in the picture below... i guess i just cranked on it too hard thinking it was a bolt and didn't realize it. And this isn't the type of plug that is supposed to be taken off like the old E46 one, this one is permant lock-in... if you must take it out, you HAVE to break the tabs.
If you're going to unscrew the blew part like you're supposed to, i suggest gripping the black part with a set of pliers and twisting the blue screw off with a soda can tab. The coolant draining process is supposed to take FOREVER i suppose... before i put the new plug in, i'm going to run some plain R.O. water through the system in order to flush out the old coolant and hopefully get the broken tabs out (if they're still in there). |

I don't really like that design. Seems really easy to break those tabs and you may possibly break it without knowing just by tightening the screw head portion. Think next time, I am going to plastic weld some notches right next to the opening so I can do a very clean, nice looking safety wire job on it.

I know this is an old thread, but the same thing happened to me. I purchased a new sleeve but I do not know how to install it. It seems that if I will just force it, the tabs will break.
Any ideas?

maybe they are to break in order to show a used part?
Does the hose have indent for the tabs? What does Bentley or those BMW repair disk manuals/TIS databases say about this?

All I did was align it and push on it. I had to turn it very lightly, because the tabs can easily break if you apply to much force. View post on imgur.com

Reviving from the grave (used the search).
I had to drain some coolant in order to change my OFH Gasket (and later Valve Cover Gasket), so i used the radiator drain plug. After i put the car together i went on a test drive, and boy did i turned into a 300HP Steam-train. Did not looked like i lost all the coolant (no low coolant light) but the engine bay was all sprayed out on the right side. It was 3am so i left it for tomorrow(today), now that i saw this thread i assume i broke off that drain plug, but then again it didn't fell off (i think, because it didn't drip/spray after i stopped the car). Did all of your plugs fell off? I am still going to BMW to pick up a new plug so any tips on installing it are appreciated, i don't want to brake it because its the last one in stock. Is it just pushed into the radiator or it has to be twisted as well? Update: It wasn't the plug, the cooling hose for the OFH was unplugged (phew). Last edited by drevan; 01-20-2016 at 10:33 AM.. |
