No cabin heat

No cabin heat
I purchased a 2000 XK8 in Naples Florida last November and just brought it to Canada. I have no cabin heat.
I have removed the electric pump, diverter valve and both are fine on tghe bench, heater core was plugged but that is now clear. The control panel has no codes and all electric power goes to valve and pump as it should.
The hose from the back of the engine on the passenger side has almost no water coming out, if I rev the ngine I get a little dribble. This hose goes to the diverter valve, then the pump. No water getting to the pump.
Has anyone got any ideas?
I have bled the system and removed the cap on top of the thermostat and topped up there as well. I am stumped.

There are 2 mechanical one-way valves in the system. They both are inline with hoses connected to the diverter valve. Make sure that the arrows embossed on both these valves point TOWARDS the diverter valve.
If that is OK, remove those inline valves and check that they are not clogged with debris from flushing the heater core.

Not necessarily...the computer controlled temp. gauge lies until the temperature reaches about 235-240 degrees. See https://www.jaguarforums.com/forum/x...e-gauge-62813/
Try monitoring the temperature with an OBDII reader to see what it really is.

Remove electric pump
I removed the header tank and the divert valve, leaving the valve bracket, to do this, undo the isolation mount nuts, tip the bracket forward to access the divert valve mount bolts. I used a tool to unclamp the hoses and a nose picker to pry off the hoses. Then I went under the car to remove the one lower nut on the lower isolation bracket, then removed the pump with the bracket. The pump had a stuck brush, so I cleaned the armature and brushes, flushed the core and put it back reversing above process. I had to replace four of the isolation bushings, they twisted apart, found some at a local hardware supplie (spaeneur) for $ 10.oo each.
I bet it took me four hours but if I had to do it again it would be half that, now that I know how to do it.
