Liquids are incompressible , so whilst they transfer pressure ( Hydraulic brakes) you can't pressurise them . The pressure is in the ( compressible) air space at the top of the chamber. If the space is too small - maybe it's been over filled a little - or if the cap isn't sealing, or holding pressure, it will vent a small volume of coolant until the pressure drops a little. Cooling systems are normally quite reliable, unless you have head gasket problems , pretty unlikely in this day and age.
So it's probably nothing to worry about. ____________________ All the above is my personal opinion, you can see my lips move, but I'm talking out of my arse.
I've been riding, and fixing , bikes for 50 years, in that time the more I learn, the less I am absolutely sure of..... |

Worth feeling the coolant hose while reving the engine, if it goes hard as revs increase, that might indicate a blowing head gasket pressurising the water jacket. Symptoms don't exactly match this but its a free and easy test. ____________________ “Rule one: Always stick around for one more drink. That's when things happen.

Make sure the radiator is clean. Flies and tar and shite can plug the core. That restricts air flow through the rad and allows over heating.
And. Water pump not circulating water around the engine will allow overheating.

A rad cap that is only working one way will allow coolant to be 'pumped' out of the system. But you will notice that the expansion tank is overfilled if that is the case. ____________________ Disclaimer: The comments above may be predicted text and not necessarily the opinion of MCN. |
