Hey,
This is my first time on a forum so i'm going to try my best to explain as much as I can in the most well mannered way possible.
The other side of the grey hose connection is causing a leak on my car. I got the mechanic to replace this hose because he was going to have access to it when changing the water pump.
My guess is he pulled too hard and pulled the other side of the connection piece thats connected to a metal pipe. I'm in a really bad spot right now because I'm not sure if theres a way to reattach the plastic piece that keeps slipping off the metal pipe.
Please let me know if someone knows what I can do. I appreciate your time and help.
Thank you

 

Go to ebay and find a replacement. And while you're at it, if there are leaks in that area of the coolant hoses I strongly you recommend you replace ALL the hoses.
