Dear Kodiaq owners,

 

My Kodiaq 2.0 TSI coolant temperature once it reaches and keeps staying @ 90C and being steady like forever during 2 hours driving journey...

But I check the engine oil temperature did go up and down according to the driving condition (mountain climbing it goes up to 110C, if freeway it goes down to around 100~105C)

 

What are you guys' experiences?

Is my Kodiaq's coolant reading normal?

My Kodiaq does the same.

The Coolants function is to cool the engine and the engine oil.

 

So ASAP after starting the Coolant gets to around 90*oC-92*oC.  The gauge indicates 90*oC but it is that not accurate, but close enough.

So the air cooled radiator and cooling fans try to keep the coolant cool, and when working does that perfectly.

 

So the Oil which is also a coolant heats up much slower and after a few miles or more miles if starting from very cold ambient temp then eventually gets to around 90*oC

then higher as the engine works harder.

The object is that when the oil goes higher the coolant / cooling system brings the oil temp back down or keeps it from going too high.

 

Hence up to efficient running temp the oil is between 90-120*oC .   

Obviously globally and by environment and ambient temp there will be big differences, but not that much, you use different oils maybe. 0w 30, 5w 30 or now 0w 20 FS LL.

ie Arctic vs Temperate Forrest.

 

*When VW Group get the Water Pumps suppliers wrong and the Thermostats wrong and sensors wrong which is often since they went from Air Cooled to Liquid Cooled decades back then people come to Forums or to Dealerships asking why does my Coolant Gauge go sky high, then right down low and why am i loosing coolant.*

Makes sense.  The systems keep the water temp at a steady 90C.  If the engine and oil work hard, they go above that, and the water at 90 is relatively cool, so can actually cool the engine.

Thanks for the detailed comments and explanations , it did help a lot.

Cheers.
