Heater Core

I have a 92 Century that is putting out little to no heat with the heater on. I assume the heater core is bad? Were is this located and how bad of a deal is it to replace one?

how's you coolant level?

Coolant level is full along with the reservoir. Originally though it might be the thermostat, but the car is not running hot at all.

Hi everybody. I'm from the Netherlands and I drive a 91-er Century custom whith the 3,3 v6 engine.It has 187000 miles on the counter and still runs strong!! ( a littlebit rusty though :icon16: ) I also have the same problem about how to replace the heater-core. How to handle? I bypassed the system at the moment because I got al the coolant inside the interior of my car. I think it's broken so replacing is nessecary. Thanks for any reply!!!

greetings from the Netherlands :smokin: :grinyes:
