Hi, My 2wd sapphire makes a strange "flowing water" sound through the firewall and into the heater box,basically all the time but worst under acceleration. I have checked the plumbing and its correct. My previous sapphire had no such trouble. Has anybody struck this before? Thanks.

 

Could be an air lock in the cooling system, mine done this when the head gasket went

Bri.

 

Thanks, that was the only thing i could think of, the head gasket is weeping down the exhaust side of the block so perhaps thats causing it? Based on that I guess theres no way of bleeding the system until its water/air tight, ie: replace the head gasket. Cheers.

 

if you have an alloy header tank the water running into it you can hear it if is low (turbo return )

 

Standard cooling system fitted, definately coming into the cabin, sounds like a garden hose leaking through the firewall. Thanks for the info though.
