Hi everyone.
New to this post.
I have a 2014 outlander.
I have issues with the heat gauge coming on.
We had been driving for about 4 hours, then the red heat gauge came on.
We drove with the heat on full blast to keep the heat gauge down so we could get where we needed to.

I've changed the water pump about 2 months ago, changed the rad about 6 months ago.

Just a few days ago I had a garage test the system, to make sure the fans came on. They did and he said that the fans worked and the heat in the system was 240 degrees with the fans running. He was leaning towards a head gasket. I asked him to change the thermostat just to make sure. And he did and the cooling system was acting the same, so overheating.
I can't smell any antifreeze or see any white smoke from the tail pipe or see any whitish milky in the oil.

I just drove it for about an hour and opened the hood touched the top hose and it was hot, the bottom hose was cool and the rad cap was cool.

Any thoughts on what it may be?

Sounds like the water is not circulating. Is the water pump working? is the radiator blocked? Was the system flushed when the radiator was fitted 6 months ago?

Cooling system issues are easy to diagnose to a trained technician

Thanks for the advice.
The water pump seems to be working and the rad was not flushed when installed.
I flushed it today, then then added the needed coolant and took it for a long drive and now everything seems to be working fine. Praise God.

So after driving it and it was fine that day.
We headed back for home, about a 17 hour drive.
We drove 8+ hours the first day, with the heat on full with no issues.
The second day we drove about 8 hours and we were a little over an hour from reaching home, then the rad blew.

Someone suggested maybe the hoses are collapsing (the inside of the hose is collapsing) and that would restrict water flow.

Seems like there's something restricting the flow.
