Jaguar XE (1st generation): Heater Core Replacement

The heater core is located inside the HVAC housing behind the dashboard. To reach it, you must remove the dashboard and the heater housing. The exact step-by-step procedure for this model and engine is not documented in publicly available service materials, so what follows is the general procedure for vehicles with this layout. Check torque specifications and connector order against the manufacturer's service information.

Difficulty: Hard Time: 8-12 hours (requires removing the dashboard and the HVAC housing) Steps: 15 Tools: Socket and ratchet set, Torx bit set, screwdrivers, plastic trim clip removal tools, plastic pry tools, coolant drain pan, hose and funnel for refilling, multimeter, marker and bags for fasteners

Part

  • 🔩 Heater core for Jaguar XE X760, complete with seals. You will also need new coolant of the same type as is currently in the system, and new O-rings or hose clamps if the originals are single-use

Step by step

15 steps
  1. Make sure the heater core is actually the problem. Symptoms: fogged windows with a coolant smell, a wet passenger-side floor mat, a falling coolant level with no visible leaks in the engine bay, and weak heat. To test it, disconnect the two heater hoses at the firewall, apply compressed air pressure to one of them, and put the other in a container of water.
  2. Let the engine cool completely. Disconnect the negative battery terminal and wait at least 10 minutes for the safety system capacitors to discharge. This is mandatory, because you will be working near the airbags.
  3. Drain some of the coolant through the lower radiator hose or the drain plug so that the level drops below the heater hoses. If you can't drain it, clamp the hoses shut before disconnecting them.
  4. If the service information requires removing the HVAC housing together with the A/C evaporator, take the car to a shop with a refrigerant recovery machine. Do not release refrigerant into the atmosphere. After reassembly, the system needs to be vacuumed and recharged.
  5. Inside the cabin, remove the trim pieces that get in the way of removing the dashboard: the dashboard side trim panels, pillar trim, lower dashboard panels, glove box, center console, and gear selector surround. They are usually held by clips and hidden screws.
  6. Remove the steering wheel with the airbag module and the steering column switch modules, then the instrument cluster and the infotainment unit. Disconnect the airbag connectors only with the battery disconnected. Place airbags with the trim side facing up.
  7. Disconnect the dashboard wiring harnesses and connectors. Photograph every connector and label them, because there are many.
  8. Remove the bolts securing the dashboard cross beam to the body and lift out the entire dashboard, with a helper supporting it. Do not pull on the wiring harnesses or scratch the plastic.
  9. Disconnect the heater hoses at the firewall. The remaining coolant will run out, so lay down rags. Note which hose is the supply and which is the return.
  10. Remove the HVAC housing. To do this, disconnect the air ducts, the blend door actuators, the sensors and the drain tube, then remove the housing fasteners.
  11. Separate the housing by releasing the clips and removing the screws, then take out the heater core together with its seals. Note the position of the gaskets, because they can cause noise or air leaks if misplaced.
  12. Install the new heater core with the same seals, close the housing, and make sure the blend doors move freely without sticking. Replace any gaskets and seals that are worn or damaged.
  13. Reassemble everything in reverse order. Use the manufacturer's torque specifications for the housing fasteners, hoses, cross beam and steering wheel. If exact figures are not available, tighten moderately and avoid overtightening the plastic mounting points.
  14. Reconnect the battery and fill the cooling system to the correct level. Start the engine with the heater set to maximum, wait for the thermostat to open, and top off the coolant. Bleed the air from the system until the heater blows steady warm air. Check the hoses for leaks.
  15. Test all climate modes, vents and airbags (the SRS warning light should go out). If fault codes appear after reassembly, the car needs to be diagnosed with a scan tool.

Common mistakes and warnings

  • This job involves the airbags, the steering wheel and wiring harnesses, and possibly the refrigerant circuit. If you have no experience removing a dashboard and no A/C equipment, it is better to leave it to a specialist shop. After reassembly, be sure to check the SRS light and the steering. Coolant is toxic: keep it off your skin and out of drains, and collect it in a container and dispose of it properly.
