V8V normal operating temp

My 2007 V8V runs with temp gauge at midpoint (50%) mostly (now done 4000km in it)


Long trip on weekend and noticed at high speed when outside temp drops to 15deg C the temp gauge drops to about 35%. As soon as you slow down to go through a town back up to 50%

Is that normal or have I got a stuck thermostat.

Advice appreciated

Not getting up to the 50% mark is a sign of a bad thermostat. Yours going back and forth makes me think it's just starting to fail.

The gasket goes bad and the thermostat has to be replaced. I've got a video on YouTube that goes over it failing and replacing it.

Your thermostat is on its way out as telum stated. Mine was like that, until the car just barely reaches the 50% mark at all during the spring and cooler fall weather.

Just buy the kit from telum's website and DIY it. I barely worked on any of my prior cars before, and it took me 2 hours to do it including a lunch break in between.

Made the same experience, new thermostat and all back to normal.
Usually my temp reading is spot on 50%, just when I really push her hard, like a 2500 Meter mountain pass, it rises to 55%. Below 50% onle from cold start on to normal operating temp.
I hope I could help

Christian

PS: 50%=90-100 C, 55%=105-110 C
