How to Fix the Heater Core on a Lancia Delta Integrale

About the Problem

A less common problem often encountered with the Lancia Delta Integrale can be the malfunctioning of the heater core.

It can be a quite challenging problem to tackle, but with the right set of tools and a little bit of patience, one can surely fix it.

Tools Required

Detailed Repair Steps

Step 1: Drain the Coolant

First, it is necessary to drain the coolant from the radiator. Position a container underneath the radiator drain plug and open it to let the coolant drain out.

Step 2: Remove the Heater Hoses

Once the radiator is empty, you can disconnect the heater hoses from the firewall. Using pliers, squeeze the clamp and slide it off the end of the fitting, then pull the heater hose off the heater core tubes.

Step 3: Remove the Dashboard

The dashboard of the Lancia Delta Integrale needs to be removed in order to access the heater core. This requires unscrewing many individual screws. Make sure to keep track of all screws and their corresponding locations to make reassembly easier.

Step 4: Remove the Old Heater Core

Once the dashboard is removed, the heater core should be visible. Remove the securing screws from the heater core case, disconnect the control cable, and then carefully slide out the old heater core.

Step 5: Install the New Heater Core

Slide the new heater core into the case, reconnect the control cable, and reattach the securing screws.

Step 6: Reinstall the Dashboard and Heater Hoses

Reinstall the dashboard using the screws that were set aside earlier. Connect the heater hoses to the new heater core and reinstall the clamps.

Step 7: Refill the Coolant

Refill the radiator with a 50/50 mixture of antifreeze and distilled water. Start the car and let it warm up, checking for any leaks.

Conclusion

Replacing the heater core is a lengthy but necessary process if you want to restore the heating functionality in your Lancia Delta Integrale. If done properly, this fix should keep your vehicle warm through the coldest seasons.
