BMW and MINI How To, Coolant Hose Quick Disconnect Clip
While I was replacing my radiator, I pulled one of the coolant hose quick disconnect clips off the end of the hose. Now I can’t seem to get the hose to stay clipped onto the radiator nipple. It’s a newer hose, as I replaced all the hoses just a couple months ago, so I don’t think the problem is that the hose end is won out. Actually, I’m not sure that I have the clip reinstalled on the hose correctly anyway. Can you help me with this? Thanks, Aldo
If the hose end will not stay connected to the radiator nipple, it’s likely that you are not getting it fully pushed on to the nipple, the clip is not being fully pressed into the locked position or the clip is not installed correctly. This is assuming that the nipple is not damaged or broken and that the hose end is also not compromised.
When installing the newer quick-disconnect coolant hoses, they can often be difficult to push fully on to the male nipple. Lubricating the o-ring that is captive in the female hose end and the barbed male connector end with coolant, silicone grease or petroleum jelly will greatly ease the installation of the female connector end over the male nipple. Be sure that the locking clip is pulled away from the hose end, in the released position before attempting to connect the hose end to the male nipple. Once fully pressed on, the securing clip should easily press in to the locked position. See the photos below.
* After looking at the photos, Aldo wrote back to say that he was able to determine he had installed the locking clip incorrectly onto the hose end. He fixed this and now the hose stays connected as it should.
