Which Radiator hose ?
on: February 03, 2020, 09:31:27 PM
Thinking of installing an inline temp gauge. Not sure which hose to install the temp sensor in. I have to cut it and install the inline temp sensor. Not sure if it goes in the upper or lower radiator hose ? I know one is hotter than the other. Any input ?
:084:
PS does anyone know the inside diameter of the hoses ? 22mm? before I start cutting.

If the only choice is between the top & bottom hoses then it has to be the top hose as this carries coolant from the engine. As the top hose is post-thermostat expect to see wild fluctuations and step-changes in temperature readings as the thermostat opens and closes though.

Ideally your sensor should be located pre-thermostat - this is where the manufacturer would fit it if it were equipping the bike with a gauge.

I would suggest you another solution:

https://www.steadygarage.com/store/aracer-cube-g-ultra-compact-obd-data-gauge-honda-cbr-250-rebel-300-500

It works fine on CB500X 2016 version - just plug and play:


It takes the data directly from ECU - engine already has temp sensor so no need to cut the hose. And you can see data from the rest of the sensors.

If I wasn't spent so much money in suspensions upgrade would buy one for me  :157: And the biggest problem I see for this thingies - they attracts thiefs like honey to flies. Sometimes I park my bike on the street and prefer to have no hitec devices on my bike.

P.D. Another video:

Now that is a very cool product for the pre 2019 bikes-I can tell you on my 2019 the temp gauge goes up to the middle which is three bars and never moves no matter how I ride
It's not a big motorcycle just a groovy little motorbike

Thanks Timur,
very interesting, small multi-instrument. Does that also fit the 2019 model, is there also the diagnostic connection under the seat?
Does anyone know whether the Aracer Cube G is also available for sale anywhere in Europe or only at Steady Garage in the USA?
Or alternative products?
A straight line is only the shortest connection between two curves ...

Good question. There are only two distributors in Europe according to Aracer website (in Spain and Greece):

https://www.aracer-speedtek.com/English/About.aspx?aid=18

Both distributors has IMHO the worst websites I've ever seen in my fu...ng life  :087: I bet even Mossad, MI5 and KGB together wouldn't be able to found Aracer product in their catalogs.

You are right Timur. I looked at both websites and did not find the Aracer.  :157:

That is a cool product, however :

1. 5 times the price with bracket and shipping.
2. I donít want to plug anything into my ECU, period.
3. Coolant hose is less than $19 if I need to replace it.
4. Much lower risk to just cut the hose instead of messing with the ECU.

So back to my original questions , 1. what is the inner diameter and 2. upper or lower hose ???

Lower hose - it brings hot coolant from engine to the radiator so it will give more precise engine temp. Have no idea about the diameter - however you can pull out the lower hose from water pump (you need to drain the coolant in any case) and to see what diameter it has.
