heater noises
i noticed last yr that my heater makes a creeking noise, kinda like a stomach growling, it does it but still blows heat, just the noise of it sounding like its hungry or fixing to explode. weird noise.... i have no ideas, like normal, i know nothing, thank you guys on here..

this makes sense, since i have had the truck there has been a vacum sound then after it warms up , no more sound.. i had to burp the system twice before replacing the water pump, but after running the heater i remembered the creeking sound. and something clicks on and off while idling about every ten seconds, no idea what that is,,, summer or winter it does that.. thanks so much for your time and input

Coolant flows through the heater core all the time, regardless of whether you have heat 'on' or not... the blend door position dictates heat 'on' or 'off'.
So the gurgle of an air bubble passing through the heater core can happen at any time.
You may also hear the A/C cutting in and out... the A/C will cycle even with heat 'on', as it is taking humidity out of the warm air.
If your low on A/C charge, that will account for a more rapid cycling 'on'/'off' of the A/C, and also a hissing sound just after it cycles 'off'.

ac charged ? lol,, it does make a hissing sound sometimes when the ac is on in summer time and you shut truck off.. the sound is not a water swashing sound, it is more a knocking sound, like a stomach growling, hard to explain, all these suggestions are right on,, if i knew anything it would help.. thanks everyone..
