my bike is overheating, i noticed it had no coolant in the radiator so i started to add some and noticed it leaking. I found where it is coming from but the hole looks to perfect to be caused by rocks or something else. Is this supposed to be there and the leaking is coming from something inside? or is the hole just coincidentally that perfect?   |

Is that a weep hole? if it is what would cause the coolant to leak as i poured it in the radiator? Not even while the engine was running

why not just check all hose clamps first and look at all the hoses

crawford I saw it pouring out of there right after i filled the radiator with coolant. I have no doubts that's where it is coming from.

I purchased both the impeller and the rebuild kit. Superjew78 Take a look at this site, it will show you how to take apart that water pump and replace the mechanical seal. That's the part that is leaking in you picture. The instructions are for a Honda Reflex but the parts you show are exactly the same so your bike may be pretty close. Be careful removing the impeller. Do it like the instructions say and remove it after pulling the pump out. I have read several stories on the internet where people followed the service manual and tried to remove the impeller while the pump was in the bike. They broke the tab off the oil pump that drives the water pump shaft. When that happens, it is split the case time. You have to replace the oil pump. Here is the link: Reflex Water pump service I did this in an afternoon on my Reflex. The write-up is very clear and I bought all the parts to make the tool at the home improvement store for less than $10. Once you are done, make sure the anti-freeze you use to refill the bike has no silicates. Silicates will eat that mechanical seal in a few thousand miles. That may be what happened to your bike. |

I used Peak premixed 50/50. It said "Phosphate and Silicate free" on the website. You could also splurge and buy Honda Antifreeze but it is expensive. |

I agree so then stick with the Peak 50/50. I bought a gallon for $15 with a $5 rebate. 2 months later I got a $5 check in the mail and I had no idea why they sent it to me  |

It was very easy to make and it worked perfectly. The mechanical seal is actually glued in with some sealant so unless you use this or the special Honda tool, it would be very difficult to remove it from the aluminum housing. In fact without these instructions, most people actually do not bother with this repair, they pay the $150 and replace the whole water pump assembly.
