Trust it or not

The dreaded temp gauge drama today. Gave the radiata a good flush and added new coolant.
Still goes hot and cold. Looked electrical so replaced both water temp sendors. Still gets up to high before settling back to normal after a few minutes. Obviously still not working as it should. Only 2 things left is thermostat and gauge itself.
Should I trust its gonna work and maybe settle or should I replace the themostat for peace of mind?
Dont know what else to try?

common problem, its the r10 resister...

rubbers post, a soldering iron and 30min of your time.

If its going hot and cold erratically then it will be electrical (instrument PCB R10). Next time the gauge goes up, (pull over) turn the car off then turn the key back to on. If the gauge is giving the same reading, possibly the gauge is right and you have an issue somewhere else. If it gives a completely different reading (which I suspect it will) then you need to resolder resistor R10.

As above.

Or, if it's gradually getting hot when going slowly up hills, and maybe the temp drops if you drive fast downhill or raise revs while stationary, then it's a cooling system issue.

and if its gradually overheating, you can smell it in the cabin.. god awefull smell, hate it soo much..

essentially when its overheating a little or getting near it, it begins to push the excess fluid into the reservoir.. which in turn pushes fumes etc out its breather hose...and let me tell you it stinks.

Big thanks guys
I aint very mechanically minded and struggle to do some things. I was really worried about this problem.
After reading the links and particularly the South African post with how to instructions I had been thinking about doing it myself. After pondering overnight the pro's and cons I thought how hard can it be if most of you took only 30 minutes to fix.
So, I got the cluster out alot easier than I thought. Pulled the back white box off with ease as well. Took it around to a mates place to solder it, put it back in exactly as they said and took for a drive. Speedo work's, temp problems fixed.
Thanks again guys
