New/Strange sounds.

2001 C4 yesterday evening after I shut the engine down I hear a "gurgling" sound coming from the very front of the car, coolant reservoir is full.

Don't remember ever hearing that sound before.

Anyone know the probable source..??

wwest,

Sounds like there may be some air-bubbles in the radiators in the front of your car?? Have you recently changed your coolant?? You might want to run for a day with the coolant bleeder valve open to help "burp" any air pockets in the cooling lines/radiators. Do a search in this forum for lots of info relative to purging air from cooling circuit.

Good Luck!! demosan :cheers:

Coolant bleeder valve...?

And no, coolant hasn't been touched since the factory.

Is it possible to have the coolant left in the engine boil shorty after shutdown..??

I had parked the C4 outside and went back later, 10-15 minutes, to move it into the garage. The gurgling noise happened as I shut the car down after moving into the garage. I could repeat at the time but now doesn't seem to happen.

Air bubbles in the coolant temporarily due to boiling.....?
