Exclamation Overheating problem

I have a 2008 JK and it has a new water pump and new thermostat (160 degree) but it is overheating. It has the 3.8 L motor. Any body else have problems like this?

Driving down the highway or on the trail? If the problem is on the trail, make sure the elec. fan is coming on. Actually maybe that year the fan was designed to run at all times???

Like others have said check the fan to make sure it comes on. As I said in your other thread, don't overlook a bad radiator cap.
