getting well pissed off with my car now

had a new ford rad fitted last week and within 1 day puddles of water were appearing on the floor, took it back to the garage and they pressure tested it but no leaks were found Drove the car down to the town today and when I got home I noticed there was water on the floor so I popped the bonnet and squezed the top rad hose (s2 erst) and a jet of water litteraly shot out of the side of the rad Has anyone else had a major failure on a rad like this, if so what do you think caused it ?

I was due to go for a set up on tuesday but thats gone out of the window, ford probably wont deliver the rad till then

anyone any ideas

 

My old cosworth blew the end tanks off rad because head gasket was leaking
