First you need to find the spark plugs! No, really! I have tinkered with engines on several cars, but I cannot see the plugs or leads on my 406. I haven't looked too hard, just a cursory glance whilst checking the oil level, etc. Are they hidden under a cover somewhere? If anyone can shed some light, I would be obliged. Thanks. Answer; They are located within a single bar located beneath the rocker cover. 1) Remove the silver rocker cover, 8 turn screws 2) you will see the spark ber beneath held down by 3 x 5mm bolts 3) Undo the 3 bolts an lift the bar off, there will be 4 rubber cups that connect to the top of the sparkplugs, you will see the plugs located within tubes, so a long wrench is required. Its not as fiddly or difficult as it may sound, just done mine and with the right tools will take approx 15 or 20 minutes to do..
on the engine
Carburettors and spark plugs.
No, a diesel is a compression firing engine and a petrol is a spark firing engine. Diesel fuel will not burn in a petrol engine with spark plugs.
If it has a petrol engine then yes, it will have four spark plugs.
it would damage the spark plugs and smoke a lot, but the engine in general should be ok, would have to change spark plugs after running tank empty or if having trouble starting.
got fuel if so is the starter motor cranking the engine over if to that means battery ok so could be fuel injection pump or carb. spark plugs if petrol
Depending on model, this engine may not have glow plugs. In engines with glow plugs, they are located next to the injectors on the top of the engine, under the plastic cover.
it could be for the spark plug, petrol engines dont need glow plugs, diesel engines do
Change the Spark plugs, if not bin it
You need to be specific as to engine type (diesel or petrol, and then which size or type of diesel or petrol), and also quote year and/or Mk number. All have different sump plugs, oil filters and so on.
They are really hard to see but they are in a row underneath the big black box at the top of the engine. Cant seem to get in there though to change them...I am having problems!
