Wooofa, Are there any other symptoms that it's running hot other than water overflowing? ? If it runs Ok but water is pushed out it could be as has been suggested 1) possibly running within correct temp range but the expansion of the water is causing it to come out of theoverflow.? ( neverfill above the baffle of the rad when cold ) 2) over-turbulence of waterpump 3) small leak in the cylinder head gasket causing some pressure in the water system .. head needs retorquing several times after gasket replacement or head off. [I've experienced 1) and 3) with my years of A-ing but never 2) ]
