97 Deville HeaterCore (Need Instal/removal procedure)


Recommended Posts

Despite I do not have 97 Deville, I believe it is under the glove box. You will need to remove the glove box, the passanger side sound insulator, disconnect the heater hoses on the firewall, probably remove the computers to get access to the heater core. Not a difficult task, I had difficulty to put it back, so pay attention to removal and remember the steps. I am sure someone with your model will chime in with directions.

The heater core on my car (1997 Eldorado) is up against the firewall high on the passenger side behind the glove compartment. You can spot the location exactly from under the hood by peering behind the engine and seeing where the heater hoses go through the firewall. Getting at it is a big job.
