If you need a heater core, the one you currently have would be leaking. If the car is over heating or not getting warm enough, think thermostat.

You have a1998 gmc jimmyandthere is no heat-the blower is fine-temperature reading ok-could this be a thermostat or is your heating core bad?
I would check the thermostat first but what it sounds like is that the coolant system is clogged up causing no coolant to pass through the heater core. If the coolant is very dirty then you will need to flush out the complete system and this will need to be done by removing the hoses to the heater core and the thermostat. Flush it out several times until you get clean water coming through........

What could be the problem in a 1989 Chevy S10 4.3 that has no heat?
Assuming the coolant level is full, it could be a stuck open thermostat or a plugged up heater core. With the vehicle warmed up, heater on and engine running, feel the heater hoses with your hands. If they are both luke warm you probably need to replace the thermostat. If one is hot and the other is luke warm you probably need to flush the heater core. If they are both hot you may have a problem with the temp blend door.
