8WA Sman Posted December 3, 2015 Share Posted December 3, 2015 I have an '11 Ecoboost that has a coolant leak @ the degas bottle outlet quick connect hose. Someone else replaced the o-ring it leaked, I tried a RTS-1078 it still leaks. FCA dos not list a seal separately that I can find. Is everyone just replacing the hose BL3Z-18472-J (KH576) and does the degas bottle also need to be replaced? I couldn't find anything wrong with either one.

tonybullitt Posted December 4, 2015 Share Posted December 4, 2015 Most of the time replacing the hose fixes them. Have seen 1 that needed bottle and hose. Quote Link to comment Share on other sites More sharing options...
8WA Sman Posted June 3, 2016 Author Share Posted June 3, 2016 Finally fixed this truck....I thought it was fixed but it came back leaking again. The quick connect fitting adapter was cracked, it was easier to see the crack on my phone(I sometimes forget that trick)Looked almost like a scratch until I pressed around on it.

mchan68 Posted June 3, 2016 Share Posted June 3, 2016 I've had two that came back leaking from the same connection. The first one came back the next day. The other one came back about 5000 kms later. Replacing the Degas bottle fixed both. Going forward, all will be getting a new bottle and hose. Quote Link to comment Share on other sites More sharing options...
