Well.. glow plugs are wired in series, not paralell like torch batteries,
which is why you still have 2 of them working while the other 2 are dead,
Of course if the plugs are easy to get at, then change all of em.. some
engines have one plug that's a pain to get at.. usually tucked behind the
injection pump mounting brackets (not landrover specific here) of course
that's the one that's likely to be gone
When you pull the old glow plugs, have a look at them as they come out of
their respective holes.. any that are eaten away, or have big lumpy deposits
on them indicate that cylinders injector isn't firing cleanly.
As for the differance in price.. it's the same with everything, the champion
ones your paying for the brand name most likely.. but some times cheapest
isnt always best.. Halfords own brand glow plugs have always been poor with
my vehicles, every single vehicle i'd fitted halfords brand glow plugs to
had at least one dead by the next winter...
ok they will change the dead ones for good uns when you take them back.. but
it only happens again later on,
If i'm buying the plugs for my own vehicles then i go for bosch ones, but
that'll be never for the next few years, as my current vehicle is direct
injection.. and has a thermostarter system.. at minus 2 degrees it uses a
single glow plug and injector combined to squirt hot diesel into the inlet
manifold as your cranking the engine, (kinda like squirting easy start down
the intake)
Never had this engine need more than 4 revolutions to fire up.. even in sub
zero temps, kinda makes me never want to go back to indirect injection
engines
