Just to cover all the bases...

It is actually overheating (separate thermometer) shows temps well above 230F ON COOLING SYSTEM COMPONENTS?

Or, it your temp gauge showing unacceptable readings?

I'm presuming when the water pump was replaced, the belt was too. And the idler pulleys (and alternator) checked?

Is your JK equipped with and engine driven or electric cooling fan? Clutch or relay/thermostat/controller issues?

If it is really is still overheating, you are looking down the wrong end of head gasket issues.

 

Temp Gauge showing unacceptable reading. It tends to happen when Im driving. While vehicle is stopped is doesnt happen.

Water pump and belt both replaced yes.

Its an electric cooling fan...

 

Are u losing any fluid?

No, not losing any fluid whatsover...

 

Take the cover off the engine, and check the oil cooler. Sits right in the middle of the engine. Mine was starting to leak, and liquid was living in the valley of the engine. This is how I found out mine was leaking:

 

That filter housing was actually replaced about 2 months ago. So thats not the problem. No oil leak... Thanks

 

Seems like I always have to ask if you also replaced the rad cap. Pressure test yours to make sure it is holding 18 lbs. If not that could be your problem.

 

Anything in front of the grille, winch, light bars, angry eyes?

 

So I finally figured out the problem! It turns out it was the aftermarket fan was not blowing out enough heat from the radiator. I put back the original and it is no longer overheating. Thanks to everyone for your feedback and help.

 

Congrats on actually solving the problem!🎉

 

The BEST electric fan is the OEM one.

 

Same thing is happening to me
