Where does my anitfreeze go By speedracer (Read 700 times)

The $64,000 question. Every two weeks I pull the cover off the overflow tank only to notice that it is empty. I add only about 2 oz of antifreeze and can see a small amount under the cap.

I have placed cardboard under the scooter and there are no leaks. The drain plug is dry as well. Is this normal?

When riding there is no way of checking for leaks and if I stop after a long ride I look underneath the scooter, but nothing there to show any kind of a leak. It doesn't run hot at all. In these temps now it barely reaches the half way point on the dash.

I have run it in the garage so that it does get hot and the fan kicks right in just past the half way mark. No leaking then as well.

Have you checked all the connections and the radiator. It has to be leaking out from someplace and probably only when it builds up enough pressure and it does this only when your riding it. They do have Dyes to find such leaks maybe putting in a Dye then you may be able to find the leak.

Alleyoop has some good advice. The only other way to have a leak would be the head gasket. This would allow antifreeze to get into the combustion chamber which might be burned off if the leak is small enough. You might also want to check your oil level to make sure the leak is not getting into the crankcase. Head gasket leaks generally show up as hard starting or even hydro lock due to water collecting in the combustion chamber when the engine is shut down.

Thanks Alley and Cruiser for needed advice and tips.

First I'm going to check the hoses for any kind of a leak. It would have to be very small.

Cruiser, The scooter starts right up even after sitting a few days as it did during that really cold weather we had. I don't have any loss of power, which I would assume with a head gasket leak.

I hope this is a simple fix.
