Radiator temperature

HI
I installed Trail tech vapor with the temperature sensor (replacing the original speedometer).
Trail tech shows radiator fluid temperature of max 107 Celsius after intensive ride (~225F) is it OK?
Do you know where the temperature indicator on the original speedometer enabled (at what temp)?
The trail tech defaults indicate danger temp from 100 Celsius (212F) do I need to change the defaults or I have real problem?

Anti-freeze works the other direction too. It raises the temperature for boiling.

You don't want boiling.

A quick internet search says normal range for internal combustion coolant temps is 195 to 200 F


Make sure you have a good mixture of water and anti-freeze/coolant in your bike.


If you were doing slow trails and tight stuff where there was very limited air-flow through radiator I'd say you're temp was probably about right.

Was your cooling fan on?


I don't know of any way to check coolant temp with stock Yamaha instrument panel.

I do recall one member here posting about hearing the coolant boiling after a ride in high air temps on very slow single-track trails.

I mostly ride on the street so air-flow and cooling issues like this are not much of a problem for me.

i use this coolant
should i modify the defaults?

By the way my fan works at about 212F (100 deg c)

I use these temp stickers thanks to Rick Ramsey

Can you tell what is your max temp?

On my FZ1, the fan also comes on at around 212F.

Max temp at enduro trails 107deg c (224F)

The boiling point of a 50/50 mix is 227F. Add 15 psi (pressure in a closed cooling system), the boiling point raises to 265F.

I also have the Vapor. I get a reading of 92-95C when just doing day to day rides and commutes. When doing slow trails, lots of 2-3 gear, I get 102-106C as a max temp and tend to run about 98-100C as a normal reading. I have seen as high as 109C but that was when my coolant level was low, and the stock temp light came on at this reading.
