wierd sloshing/gurgle sounds from dashboard

It sounds like some form of fluid flowing through a pipe. As if the pipe is half full with fluid flowing through it. I just replaced the radiator so with it, the coolant as well. Is this sloshing sound in the dash normal? Engine temps are completely normal and doesnt seem to affect the cars performance. Thanx in advance for the heads up

Probably have a large air bubble in the system, just keep checking and adding fluid when the system is stone-cold, in the morning is a good time.. Eventually the system will be full... sometimes it's hard to get it full initially... 2.5 engines had an air-bleed on them to help with this issue..

If it's not your heater then check your cowl area. If the drainage tubes are plugged water will have no place to go.
