Detach the heater hoses, unbolt the heater matrix from the unit, and replace it with the new one. Reassemble the components in reverse order, ensuring all connections and seals are secure before refilling the coolant and reconnecting the battery.

To replace the dash lights on a 1988 Volvo 240 wagon, first, remove the dashboard cover by unscrewing any retaining screws and gently prying it off. Next, locate the bulb holders on the back of the instrument cluster, twist them counterclockwise to remove, and replace the burned-out bulbs with new ones. Finally, reassemble the dashboard by reversing the steps, ensuring all connections are secure before securing the cover back in place. Test the lights to ensure they are functioning properly.
