dragerman Posted September 25, 2007 Share #1 Posted September 25, 2007 Sunday I was out for a ride with another couple, I was on my 06 Venture they were 2 up on a RSTD. It was sunny and 24 degrees Celsius. We rode for a good hour before stopping and when we did I could hear a noise coming from his bike. I asked him what the noise was and he said the cooling fan. It then occurred to me that I have never heard my fan come on and it got me wondering. So today I checked the fuse and it was ok, so I asked a Yamaha service manager and he told me that’s not unusual and that it takes a lot before the fan comes on. I’m wondering what other 2nd gen riders experience with your bikes, do you hear your cooling fan kick in and what’s the temperature around the engine like when it does? Does it make a difference when you ride 2up? When you stop after a run is your fan running? Perhaps I should test my thermostat and temperature sensor??

Squeeze Posted September 25, 2007 Share #2 Posted September 25, 2007 Hi, just let the Bike sit running on Idle after the stop. The Fan will come on soon. Link to comment Share on other sites More sharing options...
Kregerdoodle Posted September 25, 2007 Share #3 Posted September 25, 2007 I have never heard my fan come on either, and it gets plenty hot down here, but my temp light has never came on either.... Link to comment Share on other sites More sharing options...
heatonmt Posted September 25, 2007 Share #4 Posted September 25, 2007 I thought the same thing about the fan. I Even took it to dealer it takes a long time for the fan to come on. And when it does it does not run long. The air blowing through the radiator is what cool s the fluid 90% of the time. Link to comment Share on other sites More sharing options...
KeithR Posted September 25, 2007 Share #5 Posted September 25, 2007 I have 20,000 Km's on my 2006 RSMV and I would say I've heard my fan no more than 3 times. When it does come on it will shut off when you turn off the ignition tho and not stay running till cool down. Keith Link to comment Share on other sites More sharing options...
stardbog Posted September 25, 2007 Share #6 Posted September 25, 2007 Same thing with my Venture. Heard fan Kick on at gas station, and was working about 20 sec. Thats it. Link to comment Share on other sites More sharing options...
Redneck Posted September 25, 2007 Share #7 Posted September 25, 2007 My fan comes on at 220 and shuts off at 215 it takes quit a while after a stop even on a hot day before it gets that hot. When running in stop and go traffic on hot days it will run quit often. Link to comment Share on other sites More sharing options...
KiteSquid Posted September 25, 2007 Share #8 Posted September 25, 2007 I had to let my bike sit and idle for about 20 miunutes for it to come on. It ran for about 15 seconds, and did not come on for several minutes.... Link to comment Share on other sites More sharing options...
SaltyDawg Posted September 25, 2007 Share #9 Posted September 25, 2007 Personally I wouldn't just let my bike sit at idle just to check the cooling fan. What if the fan is actually damaged and not working then you run the risk of overheating your engine. My fan has not come on with this RSV, but on my first RSV I had it come on during a traffic jam several times. Believe me you will know when it comes on. You will be blasted by a 200 degree "breeze" for a minute or so. Very uncomfortable when sitting in traffic on a hot day sweating your backside off.

dragerman Posted September 25, 2007 Author Share #10 Posted September 25, 2007 Hum-m, that’s interesting, thanks. I’ll pay more attention when I'm stop at a light or in traffic (and turn the radio down), perhaps even try the idle thing and see what happens. The dealer suggested putting a piece of cardboard in front of the rad and letting it run for a bit but I didn’t want to do that if the bike had a problem. Given what everyone is saying I feel better about trying that. I think it says something about this site when a person has to check with his brothers and sisters over what someone else says. Does this mean that on top of everything else that we have a “COOL” bike! Link to comment Share on other sites More sharing options...

Vance Posted September 25, 2007 Share #12 Posted September 25, 2007 My fan does cycle on when needed, but I have never heard it. I first noticed it when I was syncronyzing the carbs. The fan is so quiet, you won't hear it come on, but you will notice an increase in heat around your legs. Link to comment Share on other sites More sharing options...
Guest tone100 Posted September 25, 2007 Share #13 Posted September 25, 2007 Now that you mention it I've never heard my fan come on either. I've only had this bike for a month but its been hot here. On my Shadow it would come on at every light and you couldn't miss it since it sent a hot blast of air up your body. Link to comment Share on other sites More sharing options...
Stoutman Posted September 25, 2007 Share #14 Posted September 25, 2007 I've only heard my fan come on twice, both times at the same backed up four way stop, and in the Texas summer. I'll drag the rear brake and slip the clutch, while going very slowly toward my turn to go through the intersection. On hot days the fan will come on after about 2 minutes of that. It is very quiet.

Al Bates Posted September 26, 2007 Share #15 Posted September 26, 2007 I have a 02 and the cooling fan would come on in hot weather in traffic, some times on the free-way with high RPM or in the garage on a hot day syncing carbs . Then one summer on a hot day when I decided to sync the carbs I new it was hot and the fan should have kick on, but it never did. So I did some testing and found that the temperature switch in radiator (there is two of them) was faulty. I replace it and the fan started working again.

The exact same thing happened to me this summer after riding up the steepest hill I ever rode up in Deadwood. It was about 105 Degrees, Got to the top and Chaos' fan was on and and mine was not. I too was curious, and was planning on checking when I got home. Actually was a bit concerned. Anyway a day later we stopped at a light and my fan clicked on. This was the first time I ever heard it.

I was riding there a few weeks back and noticed a 07 Black/blue in a Garage (in the new subdivision), as I drove by. One or two houses from 24. Could that be you ? Anyway you have a lot of members close by, maybe we will see you sometime. Brad Link to comment Share on other sites More sharing options...

Does this mean that on top of everything else that we have a “COOL” bike! That's the way to heat up the coolant in a car, as the fan runs all the time. Not so on the bike. It only comes on a a certain tempture. Sitting still on the bike would have the same effect on a car with the card board in front of the radiator.

Monsta Posted June 15, 2009 Share #21 Posted June 15, 2009 FWIW, most cars in the road today have electric cooling fans as well. Link to comment Share on other sites More sharing options...
KiteSquid Posted June 15, 2009 Share #22 Posted June 15, 2009 electric cooling fans on cars gain about 0.125 MPG, but cost more to build into a car. Like Monsta said, they are on most four wheeled vehicles built today. Link to comment Share on other sites More sharing options...
fardnarger Posted June 15, 2009 Share #23 Posted June 15, 2009 Friday in the hill country of Kerrville Tx it was 99.9 degrees and a heat index of 110, my fan came on one time, when we stop to let 37 deer cross the road, other that it didn't come on the 4 days that we were their. Why didn't someone tell me before that Texas has big hills (LOL), great riding around the Kerrville area, hwy 39,187, the three sisters etc, great rides, however I lost count on how many times we cross the Guadelaupe River.

rbjohnsn Posted June 15, 2009 Share #24 Posted June 15, 2009 FWIW, most cars in the road today have electric cooling fans as well. Thats true. It saves fuel. A fan draws ~15hp. In the new vehicles putting card board over the radiator to make the engine get hot, wouldn't apply, as with cars that had the old conventional fans which ran all the time. You could disconnect the fan to get the same effect. Link to comment Share on other sites More sharing options...
Monsta Posted June 15, 2009 Share #25 Posted June 15, 2009 electric cooling fans on cars gain about 0.125 MPG, but cost more to build into a car. Oi...off topic. Electric fans came about for MPG improvement but also due to the use of transverse mounted engines, which in turn came about due to the popularity of front wheel drive. A transverse mounted engine cannot run a fan off the front of it. Due to the widespread use, what was an added cost to use electric fans is now no longer an added cost. Sorry for the off topic reply.
