i recently bought my second cherokee, it is a stock 1996 cherokee sport. it has the inline 6 with the ax-15 transmission and only has 120,000 miles ,the previous owner replaced the radiator water pump along with all new hoses. yesterday i replace the dummy gauges with the full gauges out of my parts jeep, and noticed that the water temperature was running at around 240. the electric fan wasn't turning on so i wired it to a switch and there was only a minor difference, what else could it be??

 

Verify with a temperature gun that your gauge is reading correctly. There is a chance that it is not.

 

Have you checked the oil to make sure he didn't bust the head gasket. Something made him change the water pump...

he may have let it overheat bigtime.

 

Thanks for responding and I checked the oil he recently changed so I couldnt tell. what else should I look for to se if it's a blown head gasket?

 

You will have coolant in the oil.

 

There isn't coolant in the oil from what I could tell

 

Thermostat then?

You said he replaced the pump and hoses and what not. The obvious replacement is thermostat did he do that?

 

x2.

You should also replace your mechanical fan clutch, that could also cause you to overheat.

You should still verify the temperature. Your gauge could be off.

 

Has it been post before that sending units/sensors for the gauge dash r different from the sending units/sensors in the idiot light dash, or am I dreaming?

 

The thermostat looks new I can see new rtv. I'll try a new clutch fan

 

I will also try a new temp sender since the one I put in is used

 

This.

Maybe the temp is real, maybe it's not.

Hate to be chasing a ghost if it's not.

An infrared point and shoot gun pointed directly at the thermostat housing will tell the story quickly.

 

Very true I guess that's where I'll start

 

True I guess I will start with that thanks I'll let you know how that goes
