HI All 

 

New 20203 Fabia colour owner which shows engine temp rather than a dial on dash 

 

Juat wondering what would be considered normal temperature when fully warmed up 

 

Thanks Steve 

90°C I would have thought.

 

Easiest way to know would be to take it for a run on a regular day (i.e. not today!) and see where it settles.

Are you looking at the Coolant Temp which will get to showing around 90-92 *oC,

 

or the Oil Temp which might get to 50*oC after a few miles and then up to the normal operating temp around 90*oC which is where the coolant is trying to keep it at, and then it can increase to over 100*oC and the Coolant System operates to bring it back down again with the use of Coolant, Radiator, Fans.

As it has been with Liquid Cooled petrol engines for decades. 

Hi was looking at oil temperature

Coolant temp stays at 90 , but oil temperature was getting higher than 90 , not had a car before that shows oil temperature 

Thanks Steve

Oil temp varies, but fully hot is in the range 95-105 degrees C, give or take a bit depending on weather, driving conditions, etc.

If you want to know when your engine is warm, look at the oil temp.

Oil temp tells you if the engine is up to operating temp, 80 degrees is start of "normal" operating temp, IMO.

Water temp is engine overheating temp, and only needs paying attention too if it rises abnormally.

 

The key explanation (IMO) by Weasley is this:

"In an engine the oil does warm up significantly slower than the coolant, largely because the coolant is thermostatically controlled and only the small portion within the block is circulated at first, whereas all of the oil is circulated all of the time, so is a significantly larger mass to heat and is exposed to the cooling effect of the sump."
