I wondered if someone might help me with a odd Q ? Got my versys for over just over a year ( and 32 000km) now and for the first time this morning I took my helmet off before switching off the motor after my commute of 80km to work in heavy traffic.
Just after I switched the motor off I heard a noise coming from the overflow tank which sounded like the water boiling. It only last for a second or two then stops.
Is this normal ? My fan does work as I checked when going home. I can't make out for sure if the water is boiling or is it just water being pushed due to the pressure into the tank.
My water temp light doesn't light up either but I assume it's like the low oil indicators found on cars and when that comes on it's already to late So I don't want to take any changes.
When you kill the engine, water no longer circulates, causing the water around the cylinders/head to get hotter for a short period (until the heat dissipates). Might cause a bit of water to be pushed into the overflow, also. Don't think I would worry??
i hear this boiling noise from time to time when i switch off the engine.
its for sure the noise from hot water pushed violently to the relief tank.
i mixed different grade of coolants some time ago and now this happens,i will go for a total coolant change and inform you whether this noise persist or not
Yup, mine does it as well. Try and keep the level in the overflow up to spec. If the overflow tank is low it will be empty when you shut the engine off and coolant hitting the bottom of an empty tank will make more noise than a full one.
Falling down is your bodies way of saying you just screwed up.
