Modern Vespa

was teaching the wife how to ride the scooter... i know.. big mistake. She took a very minor spill - tipped over actually on a curb on the scooter's right side. Now I have a super high pressure stream of coolant coming out of a gasket. You can actually see the rub where the curb made contact (in the picture). I can't figure out how to try to adjust the clamp securing the gasket. I'm assuming it was knocked loose or out of place. There's no screwdriver adjustment screw like on a car clamp. Anyone have any suggestions before I take it to the dealer?

I assume you are talking about the hose. Those crimp clamps are one time use and are either replaced with a like kind or a different type like those you mention that use a screw. You could buy and install new clamp.

If there is a rub hole in the hose, then the hose will obviously need to be replaced as well.

yes i meant the hose. when the scooter cools down i'm going to inspect the area for a pierce in the hose. thanks for the guidance.

Sorry for your wifes tumble I hope it doesn't put her off long term. Looking at your photo there is a faint line about a quarter of an inch from the hose on the pump casing. That might have been the hose's original position and its been moved on the fall.

When cool, as others say remove the old " single use" clamp and see if the hose can be seated closer to the impeller before fitting and tightening up a new screw down hose clamp.

Lastly don't forget to top up the coolant reservoir when finished ✅

To remove that clamp.....insert screwdriver into the crimped part and twist to open the crimp.
Replace with normal clamp after repositioning the hose.
O.S.
