gurgle noise 300td
 

300td 79' sounds like a egr valve, but don't have one,get louder as you go faster,does not make the sound while setting still, just put in new tranny fluid it is full, made the sounds before i put it in,exhaust has no leaks,

Check your cooling system. If it is not completely full it will make the noise your described flowing into the heater core.

The coolant reserviour bottle should be full as per the book. Secondly replace the coolant reseviour bottle cap. I am sure it is taking air and thus this gurggling sound is there. I had the same problem in my Cheverlet Blazer. That weant away as and when i changed the cap as mentioned above.
Try it and best of luck...........
