Okay here it goes, I just picked up a 98' Daytona last week and have already fallen in love with it but It had a couple problems.

1) It overheats, I just flushed and changed the fluids in the system, the old stuff was nasty. and it still overheats so this leads me to think its the thermostat (I could be wrong) seeing as its got the same habbits as my truck does.

2) The cooling fan doesn't work while the key is in the ON position, as soon as the key is OFF and the temp is high its immedately kick on. To me this seems wrong.

I've got plans to take it to the local dealer and have them give it a bit of a once over and to give me some pointers, but if you folks could help me out I'd greatly appriecate it.

I'll keep searching the forums along with whatever comes up here.



Thanks,
Eric

how high was your highest temp. I know mine will get up to about 223 f. Which is normal for these bikes. About the fan i know it will kik on sometimes after you shut the bike off. Its hard to here the fan when your going though.

I'm not sure just how hot it gets as it doesn't have a numbered gauge, I do know that when it gets hot it'll make its way to the read line.

The fan itself I'm positive doesn't work when the key is on because when I do shut the bike off and the fan kicks on I can immediately turn it back to the on position and before I can start it the fan kicks off, turn the key off and it'll turn on again.

My cooling fan on my bike turns on for a few seconds when I turn the key off too (on a hot day), so you shouldn't jump to the conclusion that that means that it's faulty.
I chalk it up to the fact that coolant stops circulating through the radiator when the engine stops, so the temperature of the coolant goes up a little because it's still being heated by the hot engine, but not cooled by the radiator. This kicks the fan on for a few seconds, which cools it a little, and it shuts off.
When you say that it's running hot, how do you know? Our older Daytonas don't have the fancy digital readout to tell us exactly, but the analog gauge is there. Mine reads about 2mm past the small line most of the time. Is the needle hitting or getting close to the red zone on the gauge?
I've read about air pockets forming in the coolant line causing overheating, but I remember thinking that somenting was wrong with my bike when I bought it, running too hot. Turns out that it just pumps out a lot of heat from the engine under normal conditions, and poor fairing design directs it at the rider.

Yes these triples run hot. I have a didgital so couldn't tell you where the needle would be for the analog.

Also I will speculate this, but when you start your bike and the fan turns off, it maybe engineered for that so you get all the power to the starter. If you notice when starting a car, that the radio, fans and other electrical shut off while starting then turn back on.

And when it comes on, the fluid is flowing again and has been a little cooled from the fan being on as well, so it is cooled enough for the fan not to turn on when it is started.

Running hot as in hitting the red on the gauge hot.

It'll read the same as yours does while crusing at highway speed (40+) but in town which is usually around 35 tops its tough to keep cool.


Yes a car does shut off all electrical while starting but not while sitting with the key on, so wouldn't this be the same way with the bike? I know it doesn't kick on while the engine is running because I've checked.

like I said as soon as the key is off the fan will start until the bike does get back to normal temps. and it seems that is should stay on while hot unless trying to start.... Am I making sence?

It kind of sounds like you are saying that cooling fan _never_ runs while the key is in the "on" position; am I correct?

My fan comes on when the needle gets within 3mm (office desk estimate) of the red line. With the key on.

The bottom edge of the tank (where your thighs and other, more important regions make contact) can get a little hot, even when running 60+ mph. That's one of this cheetah's spots.

Yes sir, you are correct.

My question for you is just how often does your bike get that hot?

HiDesert

I've never seen the temp needle get to the red line. Within a few mm is as close as it gets.

The fan is usually running when I pull up outside the apartment after a ride. So 15-20 minutes of stop and go on a warm/hot day is enough to get the fan running. In those conditions, the fan can usually keep it near the middle of the gauge.

If the weather cooperates I'll pay particular attention this weekend and report back.

Mine will get there within about 15 min worth of riding and its done it every time I've ridden.
