How do you change the ignition coils in your 1999 Discovery II?
there are no ignition coils per say, there is an injector loom
under the tappet cover that has connectors going to the injectors.
to change that remove the plastic engine cover (3 bolts, 2 on left
side 1 on the right). remove the hose from the top of the tappet
cover it has a spring clamp. remove 8mm bolts on tappet cover,
remove tappet cover and the injector loom is the long plastic
harness on the right side. you will have to replace the gasket and
seal the half moon at the rear with high temp silicone. sorry i was
thinking TD5 engine. there are 4 bolts 8mm bolts attaching the coil
to the rear of the engine, they are difficult to access. remove the
leads from coil pack, you will have to remove the plenum chamber as
well to manouver the coil out.
