Coolant Temperature

[GPMAZ]

I just got back from a trip from Phoenix to Salt Lake City and back. I mounted a scanguage on my R3T a couple of months back and left it mounted for the trip.

The range of operating temperatures was rather interesting. Normal coolant temperature seems to be around 195. Running at around 65 in ambient temperatures below 50 the temp will run from 191 to 195. Above 75 or so it jumps to 197.

Now, when I got back to Phoenix this afternoon the ambient temperature was 110. Running down the freeway at 65-80 the water temperature fluctuated from 202 to 210. The higher temperatures mostly happen when following traffic. Clean air cools better. The Intake Air Temperature was reading 137 degrees. After just a couple of quick stoplights before hitting my driveway the temperature was reading 222, with the fan running of course.

The Temperature warning light never came on, and without the Scangauge I'd of course have no idea what the actual temperature was. Except for the feeling of straddling a Weber Grill. I had the headers Jet Hot coated and that really reduced the heat they give off. But, the heat from the radiator and the engine itself will still cook body parts.

It seems to me that the cooling system is barely adequate. As soon as you come up behind another vehicle the temperature rises. And, any hill will cause an immediate 2-4 degree increase in temperature.

I'm wondering what I'm going to do when summer starts in another week. Then it will really start to get hot. Maybe a custom radiator???

Um, not many people want to pay on the order of $1500 for a custom radiator when the stock one is fine under most conditions we ride. Most of us don't run often in the triple digit temperatures either.

I think if a radiator upgrade is out there, it'd have to look sleeker/slimmer as well as be more efficient. Nobody wants to pay big bucks for an even chunkier unit.

I think you'd do better with a water cooled riding suit. Go around looking like a Tron warrior. :lol:

to do a twelve minute tune(which I understand needs to be around twenty minutes after the fan comes on)

Yep! that's why we call it the "twelve" minute tune :lol:

coolant

Mine is converted to evans (waterless, no pressure) coolant. I also have a temp gage installed. It stays right around 120 even on the hottest day.

Is your temp gauge reading celsius? That would be equal to 248 farenheit which is pretty hot. I've heard Evans will run hotter but that the boiling point is somewhere well north of 300 degrees.

If your gauge is set to farenheit, something is wrong. The R3 has a 185 degree thermostat and at 120 it wouldn't be close to opening. My temperature passes 120 within a minute of starting, even in very cold temperatures.

 

[dunringil]

It's Fahrenheit and never gets over 140.

The fan does come on in very hot weather, so the gage may be inaccurate. It's just an analog hand.

On my 05
the Temp.oil in heavy trafic could reach 220 f :shock:
the fan blower would run at 210 f and get down to 185 f

In my 08
the Temp.oil in heavy trafic could reach 200 f max :shock:
the fan blower would run at 190 fand get down to 185 f :shock:

so to make a short story they don't have the same temp.senser and it a bit sad :cry:
once you get on a red light the fan blower starts right away and stay on until your on the move :x

Dead cold it takes 4 or 5 min only for the fan blower to start and the temp.oil is not even at 100 f :shock:

I'm gone get an 05 fan blower senser when ever i can

It's nice
It's neet
where your living you need those kind of meter
The case you have,may need to be rechape a litle bit :lol:

But your no nuts G-MAN 8)

I too have the scangaugeII installed.

At cooler temperature on highway it stays at 89C (192F)
The warmer the ambient temp is the warmer the coolant gets. We haven't had real warm days yet but I'll keep you posted.

Fan kicks in at 102C (216F) and stops at 100C (212F)

At idle even after the fan kicks in at 216F the temp keeps climbing to 105C (221F) then stops at 212F and keeps going down to 205F. I think it's either due to bad coolant flow at idle or bad sensor placement.
