Temp stays at 210

Whether at idle or going down the road the temp gauge stays at 210 or just a hair above it. I’ve let it idle for 40 minutes and then took it up and down the road and back and let it idle another 10 minutes and it still stayed at 210. I know the stock thermostat is a 190* and I hear these 2002 WJ’s run a little hotter with the 4.7 V8. I have a hydraulic fan if anybody has any insight let me know please.

Well.. I have a 4.0 with a new thermostat. The fan relay went out and it was almost overheating at idle..

With the relay replaced. Mine sticks at 210 as if the needle was broken there.

As far as I know, thats the perfect temperature...

Dash gauges are notoriously inaccurate, they are buffered and skewed.

Are the Fans operating and no codes stored.

the gauge is showing cold first start of day, then slowly climbs to 210 - so far so good IS there a concern?

AC or defrost have any fan speed change?

Those hyd fans tend to spin slowly even when not commanded on.

When I see the price of OEM I think aftermarket.

Yes the fan just doesn’t seem to spin that fast at all when temp gets up there it stays the same speed from start up to **** off.

The stock thermostat is 195*F rather than 190*. Regardless, just keep in mind the spec of the thermostat is just the temp when it opens and not what temp the engine/cooling system is going to be on the temp gauge.

210F is about optimum for these engines and you're likely fine with it just above this temp. If the coolant hasn't been changed for a while you could flush the system, add a new thermostat and new coolant, but you may just end up with the same temp you have now.

The temp gauge in my 04 reads about the same, and the temp according to my Torque app runs between 198-205 while driving around town. It's the oil pressure that is bogus, it is not a gauge on mine. Looks like a gauge however is a glorified idiot light that will show the same reading unless the pressure is only a couple psi, then a warning. A little late I would say.

Oil pressure gauge works as it should on my 99 4.7. Goes up to 60psi when cold and then down to 40psi when at hot idle. Around 50psi when going down the road. I wonder if the was a change in the newer ones.

There can also be differences in the temp sensors. On my old 4.0L I changed out the temp sensors and the temp shifted by 5-10 degrees.

There was, I want to say 02-03. The sensor was changed from a 2 wire that shows actual running pressure to a 1 wire that is essentially an on/off switch. As long as the pressure is above the idiot light range, about 3-4 psi, the "gauge" will read normal pressure, but it never varies with rpm or temp.

My 04 4.7 H.O. Temp Gauge generally resides at the first hash mark to the left of 210 degrees. If I stress the motor going up a 'steepish' hill, the temp may climb to 210, but immediately returns to the left hash mark after the climb. It has behaved this way since new.

Seems the oil pressure gauge changed for 03. 02 and earlier use a different sensor that is about 4 times as much dough.
