cadillac overheating
i own a 97 sts with northstar. approx 1 year ago the radiator was replaced. approx 1 month ago the heater core burst and i bypassed it with a galvinized pipe in a u shape in the engine compartment. ever since then the car would overheat when driven approx 15 miles.
I finally replaced the heater core today, and poured 2 gallons of antifreeze into the system as it had all came out with the recent overheating events. the car today actually got hotter than it ever has been after the installation of the heater core. i dont know what is going on.
i dont know how to check the thermostat without taking it out, or to check the water pump. is there anyway to check these two things?
or is it possibly some thing else i havent thought of.
I NEED HELP BADLY. I am mechanically inclined and have no problems getting greasy i just need some direction.
thanks for reading my sob story.

to check the stat, take it out, place it in a pot of water and a thermometer. heat the water watching to see when it opens.
Whether it tests good or bad, replace it with a new one.
you can see if the stat works by watching the coolant temp in the radiator, or by disconnecting the upper hrad hose .. but .. you gotta know what you are doing to not get mislead or worse, burned.
the test is only to tell you IF that was the problem or you got other issues. I expect the stat to test OK. will see.
report back ?
we will need more details to guide you then. read the help thread in the general tech section.
