thanks for all your help full answers
Andy i had checked the head gasket with pressure gauge and it gained no pressure whilst running.
i have no wish as an electrician to do the head gasket as have no access to the special tools required.
though i might send it your way it looks like such a nice job (laugh out loud)
Tony it does have the right signs for both the water pump or the cooler will investigate further
if this job fails i could always go the police for a job in CID as that's lots of investigation work :-)
