I own a 2002 Dodge Stratus R/T with the 2.7 w/135K on it. I have read your thread "Info for 2.7 owners". I have recently ran into the problem with it over heating and seeing the coolant boiling in the reservoir. Not knowing a whole lot about this engine I changed the thermostat thinking that would fix it but no it didn't. Now the questions I have would using Block Tester Combustion Leak Test still have a positive reaction if the water pump is bad? Also is the water pump replacement just as costly as replacing the head gaskets? Lastly, and I apologize for the questions, is it worth spending $1000 - $1500 on it if they need to be replaced?
