We previously covered the removal of the EGR valve for the Land Rover 300tdi engine. This time we cover the same process for the TD5.
If you missed the original article covering the 300tdi engine you can read it HERE. It explains what the EGR valve is, why they're fitted and, more importantly, why we remove them. No sense going over the background again so lets get down to business:
Tools required -
WD40 for loosening bolts/nuts the night before.
Screwdriver for jubilee clip
Small socket set
Allen key
Parts required
EGR blanking plate
Replacement tube (mine came from Devon 4x4)
Small plug/bung to blank vacuum pipe
Remove engine cowl and radiator cowl to give access to Inlet and exhaust manifolds and the EGR pipe and connectors.
EGR Valve left, EGR pipe centre.
Undo two Allen bolts on
flange connecting EGR pipe to exhaust manifold. I soaked these in WD40
the night before but both came out easy enough. The bottom bolt is
difficult to access whilst the EGR pipe is still connected.
Undo the bolt holding the
EGR pipe clip to the engine block, (centre right arrow), undo the
jubilee clip holding the air inlet pipe to the EGR valve (centre
arrow), undo the four bolts holding the EGR valve to the inlet manifold
(left arrow). Disconnect the vacuum pipe, below the left arrow.
It should now be possible
to lift the complete EGR valve and pipe free from the engine and
remove. There was a considerable amount of sludge in the inlet pipe
which I have cleaned out as best as possible, to think that was going
in with the clean air.

Removed EGR Valve and pipe.
Replacement pipe and blanking plate. Note the small rubber bung currently through the left hole in the blanking plate. This is to cap the vacuum pipe with.
Blanking plate fitted.
Replacement pipe section fitted. This just leaves the vacuum pipe to remove and deal with (arrows).
Track it back and it goes
to the EGR valve modulator just below and behind the radiator expansion
tank. On mine the pipe was colour coded and was blue. It goes to the
second outlet from the top on the valve.
Remove the connector from
the valve and cap this off with the bung in the kit. Then carefully
withdraw the pipe through the loom to completely remove the vacuum
pipe.
