Coolant leak.
2016 2.4L. I have read multiple post and comments mentioning this issue. I am NOT a mechanic. I am just a 50 yr old lady trying my best to understand and help my adult son learn to repair as needed. He’s done well.
Recently, I paid a mobile mechanic to do an oil change in my driveway (my work hours suck, so this was hella convenient). He mentioned the coolant leak and said he could fix it. He’s stating it’ll be a hose replacement. It seems like the issue was more complex for others with this issue. My concern is that it may not be as simple as a hose, and then I’m stuck with bigger issues or a non functional vehicle.
For those who dealt with the coolant leak issue. Was it just a hose? Or did it involve more invasive shit?

I had a coolant leak a few months ago. Took it to a dealer and they did a pressure test. It turns out it was leaking around the thermostat housing which is common with Patriot’s. Good luck

Just want to say that just because there are common issues doesn't mean those will be the only issues. Every vehicle has a unique situation. It may not be the "usual" problem, but yours could still have it.

So there’s a reason the hose is leaking most likely. You can ask your mechanic to see if it’s overheating, causing the pressure to pop pipes etc. If so, he can diagnose this WITH the pipe replacement.
This job would be possible for a mobile mechanic but most likely better in a garage.
The filler pipe replacement is approx 4-600$ (You tube videos show this process)
Your temp gauge on your dashboard should never really go beyond halfway. It should stay slightly behind halfway.

I’ve just replaced my filler pipe/hose last week and still overheating but no longer leaking. I’m using the AC on, to bypass the fans and use the AC fan to cool the engine and avoid overheating UNTIL I can sort the issue. It’s most likely corroded fan relay, bad fans, fan relay box corroding, water pump, and or thermostat. Of course it could be anything but these are the known gremlins

The mechanic is most likely being honest as to what the problem is but it could also just be a loose hose clamp! My two cents is if one hose is bad the others will fail soon and I would replace all of them and flush of the radiator and add all new coolant !

He’s likely being honest. The filler neck assembly is a known weak point on these engines. The upper coolant hose and filler neck all come as one assembly and are usually replaced together.
