How can I flush the heater matrix (or evaporator core) in a 96 jaguar xjs? Would prefer that fix instead of replacing the core...

SOURCE: 1988 Jaguar Vanden replace headlight

What you need to do is remove the 2 screws on the top bezel from inside the engine bay, then underneath the outer corner of the plastic headlamp surround there is a philips screw, (put your head under neath car near from wheel) loosen the screw, do not remove it, now the headlamp plastic bezel/surround will come free enough so you can get a philips screwdriver in through the middle of the headlamp surround, there is a chrome retaining ring holding the headlamp in place, loosen the 3 philips screws (do not remove) The retaining ring will rotate and you can slide the ring out from the outer edge of the headlamp surround. The headlamp will then come out throught the middle of the surround, disconnect the 3 pin multiplug and reverse process for install.

you have air in the system!! you have to unbolt the filler tank and lift it 5 inch higer first. then loose the right hose on the heater core( this hose have and hole to bleed the system) and then put antifreeze until the antifreeze will go out of the hole then re install the hose to the heater core, then ajust the level correcty
have fun

It is your heater core, there is nothing else left.

The heater housing is usually under the dash, and it must be removed to gain access to the heater core.Procedures for removing a dash, and heater core vary. But for the core:
The heater housing must be removed, and then you
"remove the panels" or "split the case" (Usually screwed together.)
Remove the coolant hoses, the cable and vacuum control line.
Remove the heater core bracket and clamps.
To install the new heater core, reverse the removal steps.
Core leaks **** because of the core's location deep within the firewall/ dashboard of the car.
So remember to liquid test your new one before you put it back in, or you could be sorry.

SOURCE: Have no heat. Have replaced heater core,

I don't know your vehicle, but does it have a blower door tucked in where the heater core is? If it DOES and that's broken then it could be the whole problem. It would mean it isn't switching from the A/C side of things to the heat side of them. Hope this helps, good luck! Also, just looked up the proper name for what I'm talking about, it's called a "blend door" and I think your car has one. It's what I would check, again, good luck!

SOURCE: flushing the heater core

I removed the hoses and took a air nozzle at low pressure and blew in the return hose connection of the core. A big chunk of paste like substance shot out then pure liquid. I put the hoses back on and tested it. Now its blowing hot!!!!!!!
