2003 Ford Escort Heater Core Parts Questions & Experts Answers

• Q: How to service and repair the heater core on 2003 Ford Escort?

  A: Begin heater core service by performing a leak test when removal is necessary because you suspect a leak. The service and repair of the heater core should start with instrument panel removal and air cleaner outlet tube disconnection. The first step involves clamping then disconnecting each heater water hose from the heater core followed by removing the antenna lead from the housing and taking off the vacuum control motor vacuum connector. The vacuum lines must be pulled off the retainer of the A/C evaporator housing before you can disconnect the windshield defroster nozzle connectors by unscrewing their pin-type retainers. Start by rotating the A/C evaporator outlet duct clamp screw before removing both retaining nuts at the lower and upper heater core housing and finally extracting the heater core housing from its position. To proceed with the heater core extraction you must first remove the heater dash panel seal together with its screws along with the heater core cover. The installation process only requires reversing the steps of removal while applying coolant hose lubricant or plain water on coolant hoses to clean and lubricate them before filling the engine cooling system.
