Having got my engine cover off Ive fallen at the first hurdle :( Is there a knack to getting the leads off the glow plugs? The gap between the engine and inlet manifold is small i can just about get a couple of fingers down but having trouble getting the leads off and i dont want to damage them any thoughts ?
 
U have to struggle with them like this m8 if u dont wanna do a bigger job and loosen the inlet manifold just to make more room.
 
Yeah they are a bit fiddly farty. The leads do just pull off though and are not prone to being damaged during removal so stick with it.

Yep - changed mine a few weeks ago - long nosed pliers. Then when you come to take out the plugs you will need a socket set with an `articulated joint', a bit like a cv joint as its difficult to get a straight drive on the socket.
Hope this helps.

Why are you changing them - unless its minus 20 it should start fine without them.

:confused::confused:. so why are they fitted then? mine was taking longer to start in a morning and i replaced them, now it starts instantly. So.... i guess they do need them. People think td5's are superior diesel engines that should start in minus 5 weather with no heater plugs hahaha no chance. There same as any other diesel engine also they stay "glowing" even when engine is running when its cold until the ecu thinks the engine is warm enough

Engine is now harder to start in the morning when its cold (not majorly cold just below 7 degrees C), it feels like its only firing on 3 or 4 of the 5 cylinders for about the first 30 seconds, I was told this might be down to faulty glow plugs
 
Think I'd be looking at getting the fuel pressure checked.A Td5 should fire straight up at 7c without waiting at all for the glow light to go out.Yes,the glow plugs will help for sure if its really cold,but in most climates they do more to help emissions post starting than they do to help actual starting.With all the TD5 disco's and defenders I get in at my workshop to service or repair,I NEVER bother waiting for the glowlamp to go out.
If you are worried about the glow plugs not working for emissions reasons it would be sensible to have them tested by using an inductive current clamp to see what they are drawing - before struggling to change them.
 
Every time I start my TD5 it runs lumpy for the first couple of seconds, I thought this was down to the 5th cylinder needing just that little extra time to warm due to not having a glow plug at all?
 
Mine does the same thing, Fires up but like you say runs really lumpy for anywhere between a couple of seconds to 10 seconds or so...any ideas?? :confused:
 
I had the injector harness gasket replaced and the ECU etc all cleaned out about a year ago now so any residual oil that was in the loom etc shouldnt be affecting it still.
 
I have a 2003 Def 90 Td5. My daughter has a 1998 Def 90 Td5. My glow plug light gies out in seconds. My daughter's takes much longer up to 20 or thirty seconds. Her 90 starts only after glow light extinguishes and not too well in cold weather. Interesting comments on starting without waiting for glow light to extinguish.....6yr old battery suspected so will replace. I swapped batteries and hers now starts better, her battery in mine turns over slower. New batts. all round methinks, but still not 100% on whether a glow plug issue as well......?
