Is 104 degrees normal?(temperature stuck in traffic)

Took my first ride into central London today. Whilst stuck in
traffic I noticed that the coolant temperature reached 104
degrees centigrade. Is this normal?

It's been a while since I have ridden in heavy traffic. My vague
recollection (from the days I rode in Bristol) is that the fan used to
kick in at 100 degrees.

My K5 went to 103 degrees yesterday before coming back down. So would guess it's normal.

I think my fan cuts in at 104, and it will get that high reasonably easily when crawling in traffic. So yeah fairly normal.

pretty sure that's normal, i think it's only when you start to see 120+ you should worry! the fan kicks in at around 100 or so, i assume that is why 100 is the rough upper limit for the temp.

My temp gauge is broken i think, It reads in the red all the time when the engine is warm - but the fan has only come on once...

I have a K6 and the fan kicks in at 104.

NO IT IS NOT!

You're obviously not filtering fast enough

Traffic? what's that then?

On my K6, the fan comes on at 100C.

Your 104C is a little high, but however, the manual does state that she should be happy with anything up to 120C. At that point, you want to be hitting the Kill switch & pretty fast IMO.

104C is nothing serious.

Interesting fact time: Because the coolant system is under a certain amount of pressure, the water and coolant in your system wont boil at 100 degrees. It is to do with the pressure/temperature relationship. The higher the pressure, the higher the boiling point. If you were to take off the rad cap then it would boil as it would then be at atmospheric pressure. This is why you can't make a good cup of tea up a mountain, because the boiling point of the water reduces due to the lack of atmopspheric pressure. I think. Don't quote me. Please.

Sorry to de-rail.

So pressure is increased in an engine, and water boils at a higher temp. Pressure decreases at the top of a mountain, and water boils at a higher temp????

Sorry, I know you said not to, but I had to
