    Just about any sealer would do. It's low pressure and temp.

    Liquid teflon. It comes in a can with a brush.

    What else can be used if not teflon tape? Just curious...

    I replaced the fan switch on the R1 so that the fan came on at a lower temperature. I used one for an older Accord.

    The issue when replacing it is likely to be the connectors on the switch. Might be easiest to pull the old one out and take it to an auto parts shop to match it.

    How much coolant you lose depends on where the switch is. Leave the radiator cap on and it should drain slowly.

    Check around, as I'm sure there are plenty of different switches that would work. You might as well flush it out while you're in there. I've had temp probes that just poke through the rad fins. Cheap and painless.

    Radiator fan and temp gauge questions

    Got stuck in traffic today and the temperature needle got over the red section at the far RH of the gauge. Was almost over the "H". And the fan never came on...
    From memory, the fan is supposed to engage about at the ¾ of the needle's travel; Am I right to think so?

    Later today, I jumped both connectors on the thermostat and the fan came on instantly. From this I suspect the fan switch to be defective. Any thought or confirmation?

    Also, I think there are some automotive switches that bolt right on and that are quite less expensive than OEM Kawasaki ($75 !!). Anyone remember what automotive replacements are usable on the ZX-11?

    Finally, when replacing the switch, is there some coolant loss at the radiator or it is negligible?

    Thanks!
Working...
