Water fall noise?

[87M-GTE]

My temp gauge(BHG gauge) went up higher than normal... and it made a water fall sound. I know its not a BHG, but what would cause that kind of sound and a random rise in temp?

air in the system...

Get the coolant system pressure tested...check your cap and thermostat for proper operation.

Yeah you probably have air in your cooling system, listen to jdub.

+1 for listening to jdub...

Out of curiousity, how do you know it's not a BHG? I hate to panic you or jump to conclusions, but if you want to FOR SURE whether or not it's a BHG, get the "block test" where the color temp of the test fluid changes from blue to yellow in the presence of combustion gasses...

Just trying to help...
