How to fix engine cooling system problem

My engine temperature gauge keep going up to hot. While it never boils over, the upper radiator hose is always hot, but the lower one on the driver side is cool. Also it radiator fans continuously runs. No engine lights are on and it seems to happen when I drive. I took it to the shop and they replaced the thermostat, radiator and a coolant sensor. The only thing not replaced was the water pump. When I picked it up today, drove around for about 10 minutes the fans kicked on and the gauge slowly creeped back up to the hot zone. When popped the hood, again no boil over, no overheating smell and the hoses were the same as described before. Any idea what's going on before I attempt to have it repaired again?

That is a question you should have asked the Dealer or Local Shop.

Obviously they knew the problem was not resolved &
gave you the car back. A road test would have confirmed
the problem was still there,it worked for you.

What you have is failure to properly diagnose the customers
original complaint. Take it back.

Either Engine Coolant is not circulating as it should or you have
a failed head gasket, or timing chain or cam actuator issue,causing
the overheating.

Maybe the Exhaust Converter is Damaged & Blocked.

Lots of reasons a motor can overheat.

I would take it to the same shop first,then consider maybe they
are not the one you should be at & go elsewhere & start over.
