Report "I have a chrysler voyager 3.3 v6 reg 2000, there was immense water pressure then my heater started blowing cold, stopped the car and had it towed home, it sat outside for 3 months and has now been picked up by the garage, when moved found 2 core plugs, the garage has also phoned to say they need to put a new water pump on to pressure test as the old one has seized, could this be the original problem or am i looking at spending a lot of money? thanks"
