hi everyone
I need help my radiator is leeking water out of the filler cap but this only happens when engine is at temperture (fire blade engine) its like the pressure is building up and releasing out of the filler cap or somthing, i'm not sure wether i,m getting a air lock or maybe the radiator fan needs to be on all the time, please help

Sorry - couldn't resist.... I'll get my coat...

Chris

PS - wonder if the cap needs a new seal...

if its a pressure cap it sounds like is just doing its job

Note -- you should only have one pressure cap on the cooling system if you have two ie one on the rad and one on an expansion bottle it can cause air locks.
