Thread: Td5 Glow Plugs

remove the wire with 45 degree long nose short tip pliers remove the glow plug with a swivel drive and suitable socket. some brands will need it to be a deep reach.

i usually get to them by removing the intake manifold. lets face it thats going to want cleaning out too.

You can test them in situ by measuring resistance across it's terminal and head...a good one has very close to 0.9 Ohm

Re removing glow plugs, I don't know if they snap off at the base on the D2s , but on Disco3 and RRS 2.7s and RR L322s appear to do this.
I just watched a vid on the broken removal process on a L322 3.0 litre .
Makes me think twice in attempting to remove them.

When they were changed on my D2 the cylinder head had to be removed cos the heating element of one was bulged, it snapped inside and was so stuck that there was no other way just to be tapped out with a taper pin from outside

Question, are glow plugs really necessary in most of the Australian environment? It's not like in countries that have harsh winter conditions. May be some one living in Thredbo over winter then yes, but for the average driver?
I had a few people mention that they aren't really needed for most.

IMO they are needed anyway as long as it's not certain that the coolant tenmp will always stay above +20*C cos they are not there only for starting, the "post heat" operation is important to prolonge the engine's life and protect it from excessive deposits, for this mode the plugs are kept under feed after the engine was started untill the coolant temp reaches 20*C

they are needed on everything after the TD5 as the glow plugs help stabalise the cold (or cool running) light of pattern as well as providing the heat to start off the process of getting the fire down to the DPF to regen it.

I have never had my Glow Plug light illuminate in 3.5 years , even with temperatures below 20C Eg say 15 or maybe less on my dry sensor Gauge which is pretty close to my ECU sensor reading.

This includes a trip to Swampy Plains where it gets cold at night.

Is this covered by a fault if one fails?
