Spark Plugs

Post by Duncan22 » Thu Jun 14, 2018 6:06 pm

Like a number of people on this forum I tend to do my own servicing.
Looking at the workshop manual for the Juke 1.6 petrol tenka it appears changing the spark plugs is not as straight forward as on most cars due to the number of items to be removed and the cooling fluid to be drained.
Ok not a major task which I accept is something only needed doing every 2 or 3 years depending on mileage but still seems odd

Hi Mate, I have never known the cooling fluid to be drained when changing the spark plugs.
I have only removed the engine cover, then the individual coil from each plug and then unscrew the plug.
Then the reverse to install the new plug.
Its only a Juke if it's RED.

Thanks for your reply.
Looking at the Hayes workshop manual 1A.16 section 26 park plug renewal it says ' On 1.6 litre engines remove the inlet manifold as described in chapter 4A section 14.
That goes on to describe draining of the coolant etc.
Has the Hayes manual got it wrong ?
Clearly you have renewed the plugs without the need to do this, seems odd Hayes made such a mistake anyone else with a copy of the manual have comments on this ?

Looking at the engine on my 1.6 petrol Juke (2012) I can see no way the cowling can be removed without first disconnecting the various hoses.
Can someone with the same engine confirm it is possible to change the plugs without disconnecting these hoses.
Pity there is no youtube video that shows the proceedure

REMOVAL
1. Remove engine cover. Refer to EM-25, "Exploded View".
2. Remove air inlet tube assembly. Refer to EM-31, "Exploded View".
3. Remove ignition coil.
4, Remove spark plug .
Its only a Juke if it's RED.

Bernie,
Thanks but at the risk of sounding silly what are you referring to EM-25, " Exploded view" ?
I guess it's some sort of manual or link to something on this site.
Please advise.
Thank you for your help.

Hi I have only just noticed this subject. However the instructions are very different for the Turbo engine and natural asperated version.
The instruction from Bernie are correct for the Turbo engine.
For the normal engine the inlet manifold must be removed the Haynes manual is pretty good except you dont need to drain the cooling system just remove the cap from the rad to remove any pressure and have a bit of rag to mop up the small amount that will leak out when you unclip the hoses from the throttle housing.
You also dont need to remove the header tank just unclip it and move it to one side so there is enough clearence to remove the manifold.
I found I need a special spark plug spanner as it was smaller then anything I had.
I would also recomend a new manifold gasket.
Despite everything I found the job not as bad as expected when I did it a few weeks ago.

@vum,
Thanks for that, as you say the Haynes manual clearly states that the coolant needs draining but you have managed to do the job without the need to do that.
Seems there are a fair range of engines used in the Juke.
Will check out the size of spark plug spanner needed, I have a very old ford plug spanner that is small so might do the job.

That sounds like a really dumb design if you need to lose/drain coolant for the spark plug change
