Hi Do you mean heater coil, or heater CORE? Im am going to try one tomorrow or the next day. By the manual it does not seem too bad, but you may need a special tool to disconnect the heater hose from the core.

It is called a Heater Core not Cord. It is located inside the vehicle mounted on the firewall on the passenger side. It is buried behind the dash components. If you raise the hood and look on the firewall, passenger side, you will see the inlet and outlet coolant hoses connected to the Heater Core.

Doesn't matter which way the water flows. The heater core is just a tube with fins and water can flow either direction.

remove panel cover in middle of car under dash where the heater core hoses are at that go through the firewall under the hood, this is where the heater core will be located at inside the car start removing screws, until covers come off remove the hoses first though i have to replace the heater core in a 93 Bonneville tomorrow good luck

You have to remove the upper headers and it should be there toward the radiator and the fuel rail

Check your thermostat first, if that's OK then your heater core is likely bad

From where I can get the block heater cord for 94 Acclaim?
