The temp gauge on the instrument panel was

I drive a 2000 Jeep Grand Cherokee, 4 litre, v6. the temp gauge on the instrument panel was wavering between 210 and 260 for a few days. then it went to the red line and when I opened the hood, I noticed that the top radiator hose was bulging near the connection to the thermostat housing. I replaced the thermostat, but same thing happened. the top radiator hose gets hot, but the radiator cap does not. any advice?

Sounds like the radiator is clogged, have the cooling system flushed, the water pump pumps water into the engine and it comes out the top hose to return to the radiator to circulate through it to cool, if the radiator is clogged the water pressure will build on the top hose, also look at the bottom radiator hose, if it collapses when you rev the engine the radiator is clogged, although sometimes the bottom hoses are reinforced with wire to prevent them from collapsing so just because they do not collapse it does not mean the radiator is not clogged.

Change the sensor, but it will run hot like that if you are not moving fluids across it. It is basically measuring air temp for a minute. Could be a totally stuck thermostat. Change both. That cooling system is critical on a cherokee.

2004 Jeep Grand Cherokee temp gauge high when heat is on

If your "check engine" light is turn on, I suggest scanned the PCM to know exactly what fault code is stored there. Additionally, could be some problem with the "temp sending unit".

2000 Jeep Grand Cherokee with a 4.0L engine... the temperature only rises to about 150 degrees and stops... sometimes lowers a bit even at highway speeds. Normal operating temp is about 210-215 degrees. ...

The thermostat controls the temp of the engine. The temp sensor tells the gauge what temp to display. If the heater is still putting out a lot of heat then it may be a false reading temp gauge. If however the temp is noticibly cooler then replace the thermostat. A stuck open thermostat would also cause the engine to warm up slowly. check for a loose/dirty connection at the plug on the temp sensor.

Normal coolant temp for 2003 Jeep Grand Cherokee city/highway V6

Your Jeep should have a 192 or 195 degree thermostat. Do u have to add coolant once in a while? If there is no coolant loss, no overheating problem, u shouldn't have to worry about it, it could be the temp. sending unit is not accurate. If it concerns u it would probably be worth it to remove the thermostat, check the temp rating on it(it should be stamped on it). Replace w/ a new one, and see what it indicates for temp then. Good luck, let me know what u find Curt

Guages when crazy. Now won't even try to start.

You likely have it repaired by now but it sounds like a classic case of oxidized battery or cable connection (sometimes mis-diagnosed as bad battery but cured with new (clean) battery)
