gurgle
 

hi guys i have just bought my first rx7 and am very happy with it but when i turn it off after a bit of a run i am getting a gurgleing sound. is this normal or am i about to dig deep and shell out some coin.

like, gurgling coolant in the overflow tank? mine does this too. most will tell you it's a sign of a bad coolant seal. and I know my engines about to go.

when third gen engines are shut down, it is common for them to gurgle.

It's probably nothing more then your coolant boiling because these cars run so damn hot...summer time my coolant boils but winter time I get no boiling/gurgling sound.

Most of the gurgling is the water boiling off in the turbos!
Run a 16psi radiators caps.

Try replacing both caps first... fixed mine.

The noise your hearing could be the AST doing its job!

Mine was the filler cap.
