spark plugs on 2.5 160 V6

kmtranter · 14th June 2012, 15:20

I have a misfire on my ZT-T and want to change the spark plugs, had a quick look at front three. Removed cover to gain access and on the plugs there is a bar covering all three (sorry don't know proper name for it) i'm assuming this has to be removed so i can remove the coil packs. My problem is how do you remove it ?

How old is your ZT, are the front coils the pencil type or bolted to the inlet manifold ?

sorry its a 2002 model
I saw on another thread a picture of the bit in question with the yellow tag if that helps
on another issue when i took the cover of for the front plugs there was a pipe going across the engine block into a T connector with two pipes going of one to the front and one to the back the pipes keep coming of this connector so it will need replacing any idea what it might be called

not sure about the bar going across the plugs? are the spark plugs caps bolted into place? the T piece can be changed with another one, you can buy one from hallfords or most other motor factors, just make sure you take the broken bits out then push fit another T piece in place

Remove the rear centre bulkhead panel 2x8mm bolts for access.
The rear coil packs are secured by 2x8mm bolts.
Be careful of an 8mm bolt for an earth strap doesnt get removed and forgotten to refit.

Front bank - straight forward enough to remove the leads and get in there.
