Hey folks hoping you guys could help me pin point some noises I've been hearing from my bronco. It's an 89 with a 5.0L edie bower 4x4.

I've been hearing a gurgle/growl coming from the center of my dash or maybe around the Trans hump or in between the two. It will normally do it in second gear under slow acceleration and then again once it's into over drive until I hit about 55 and then it stops. It doesn't do it every time I drive it but it had been doing ever since it's been in the family that I can remember. My grandfather used it as a beach truck to go surf fishing for probably 5 or 6 years then recently decided to get rid of so I saved it from being hit with hammers and bats at a church fund raiser. So it's a pretty ruff truck but strong as all hell. The second noise is a new one it's only been doing it for a few weeks. It's a mix between a growl and a rattle only hear it at low speeds and at stops but if you power brake it slightly it will go away. It also doesn't make this noise all the time either I checked the exhaust and there's no heat shields rattling now broken hangers. So I'm at a loss.

Thanks for any info!

 

There's probably some air in the heater core and until the pressure builds up it gurgles.
