I have a 1999 2.5
Engine temp gauge is fluctuating between normal (half ) and 3/4 to 7/8 toward hot , doesn't make a difference if at a stop or under load just randomly fluctuates when driving.
Fan is spinning "freely" by hand when cold and hot , just had it idling in my driveway up to 3/4 on the gauge and fan is spinning the whole time. When idling it's almost pegged at 3/4
I removed the radiator cap and started the truck and had slight bubbling , nothing too much but it would bubble intermittent. It really settled down and I put the cap back on but the gauge was still pegged at 3/4
Running full heat does not effect the gauge reading.
Switching to ac or defrost mode makes it bubble more.
Level is good in coolant overflow tank at cold level.
When cold starting the gauge still reads at half (normal) instead of cold but it is very hot here?
What do I need to check next or replace ? Sending unit issue? Air in coolant system? Previous owner replaced lower rad hose recently , I don't know what else they did or of they boogered something up.
Thank you
