Overflow tank bubbling - ZR-1 Net Registry Forums

G'day there,

I have had this exact same problem a few weeks back when I took the Z for a drive. It was a very hot day here in aus (about 95F).

Car was running very hot, and once turned off the coolant in the reservoir was bubbling and then heard bubbling in the high fill engine reservoir.

According to Marc, he suggested to check the radiator for debris and also check for a worn out thermostat.

Could also possibly the radiator cap not holding pressure.

Hope this helps, have not had a chance to address mine but will keep an eye on this
