Gurgling from coolant overflow tank?

[O5berylgrnrenegade]

Since i purchased my 05 renegade i get gurgling from the coolant overflow tank and a kind of rushing of water sound now and then i dont see any loss of coolant except maybe an 1/8" in 3 months i do know the thermostat was changed as well as the upper rad hose before i bought it. There is no exhaust smoke or power issues and the sounds are not consistent is this air in the system? Or is there an underlying issue?

Probably a bit of air in there from the Tstat rad hose change. It'll probably work its way out with time. Just keep an eye on the level.

Thanks i have been checking on it often just never owned a vehicle were it was mounted on the firewall and could hear it so clearly

Shouldn't really hear anything unless its over heating in most cases

Probably got a bit of air in the heater core. Mine did this for a bit after one of my radiator changes. Eventually worked its way out.

Shortly after the last time I changed my radiator coolant started boiling in the overflow tank I tried bleeding any air out but it did not help, turned out to be the seal of the tank lid was bad. pressure seems to be a big factor in the boiling point of the coolant.

Could try opening the bleed screw on the upper coolant hose when the Jeep is running. Keep it open until the air bubbles are gone. I think its an 8mm Allen wrench.

This is on a WJ but same thing. https://www.youtube.com/watch?v=bKRC5Svju8s

Mine was doing the same thing. A new coolant tank cap fixed it.
