Ok.
My tired old MJ was bought with an MIL
I Found a used cannister with plug in sensor for £8.. and an internet trawl found the £70 to £80 filters could be bought for @£10.. so I am all set.
Current MIL : FUEL TEMP. and CONDENSATE
2 x faults.. a forum search said they were all in the 1 x sensor.. bottom of fuel filter.
The only forum info is for a panda mj.. the filter is different.. talk of a special ring tool is SCARY..
This job requires:
1 x filter
1 x 10mm socket.. (or spanner)
@10 minutes.. using finger and thumb.
A catch tray is useful. @0.5 litres of 'waste diesel' is emitted.
METHOD.
I had left the car stand for 2 hours.
No heat..no pressure.
Leaning over RH Wing.. with bonnet up.
Unclip the sensor plug(clip on rear edge..prise tab and wriggle downward)
Slacken the M6 bolt on filter clamp brace.
Then squeeze together the COLOURED SQUARE TABS .. on the diesel pipes on top of filter..
SQUEEZE both sides of the COLOURED SQUARE.. to release the grip.. then wriggle upwards.
DO THIS FOR ALL 3 PIPES.
no need to touch the HEX. Nipple.
The pipes are semi.rigid
So will keep their relative position..
(And are are different diameters and heights.)
Now unclip the filter brace.. lowering the filter.
Pass filter out from car
Invert filter over a container.. diesel will flow slowly from the 3 x nozzles.
Unscrew the sensor ..RH THREAD..
This will vent the filter.. faster flow
On my cheap replacement filter..
The taller extension was not supplied..
so 30 seconds had the spring clip removed
Extension wriggled free. Wiped clean
And inserted into new filter.. then re.clipped.
Reassembly into car;
There was a small bracket on my '07 mj75
That supported the HEX.NIPPLE.
This helps with orientation of the filter
Swing the clamp brace back around filter.. insert the M6 bolt
Gently re.attatch the 3 x hose fittings Squeezing the coloured tabs as they slide over the tubes.
Listen for a 'CLICK'
Then release tabs.. and gently check the hose fitting cannot slide back off.
Once all 3 x hoses are back on the filter
Tighten the M6 bolt..
Plug in the sensor wiring.
BLEEDING:
this bit I was dreading.. RELAX...!!
OK. The system has a small pump and filter in the fuel tank.(aka lift pump)
Fuel flows to the underbonnet filter
(Shiny and new )
And on to the HIGH PRESSURE PUMP.
The other line is a RETURN to the fuel tank. (Hence no stored pressure after 2 hours )
Sit back and relax..
Turn ignition to MAR (test lights.. glow plugs. Etc)
Listen to lift pump.. under rear seat..
GURGLE GURGLE.. then a few seconds of whirring.
Turn ign off and back on to MAR.
Once gurgling stops and pump runs to positive stop (system pressure achieved).
Turn ign off.
Then step out.. check around diesel filter for leaks.
Should be bone dry.. any damp needs investigating...!!
Then ign back to MAR. Let pump run for @10 seconds to positive stop.
Start engine.
Should run perfectly.. mine actually felt better
Results:
A nice experience.
No leaks.. little mess or pain.
The MIL was on.. but disappeared on the 3rd day (resets after 3rd 'clean start')
I hope to add pics into a proper GUIDE but was sitting around ..
so have done 'the basics' here.
