Changing Spark Plugs With UIM In Place
Background
I've noticed this keeps coming up in the V6 section so i've decided to write a Howto on it pictures to follow. If you use the right tools is a simple task which should take 15 mins max
Parts
- Decent spark plug socket
- 3/8 wobble extention bar (about 3" or 4" should do it)
- 8mm spark plug socket
- Feeler gauge
- Rachet
Short piece of garden hose (slides over porcelain top), to start new plugs in place, stops cross-threading them.
Procedure
- Set your spark plugs up to 1.3mm with the feeler gauge
- Start with the rear ones. First pull the HT leads off one at a time so you know which one goes where. It's cramped back there, so if you can't reach gently pull the lead with a pair of pliers - but don't grip it too hard because it's likly to damage the lead... For the one closest the coil pack unplugging it from the coil pack first may also help.
- Put your socket on your extension but leave the ratchet off
- Lower the socket and ext down the hole to the spark plug and make sure the socket meets the plug straight then connect your ratchet to the ext.
- Gently unscrew the plug making sure the you keep it in alignment (other wise you stand a risk of breaking the porcelain top of the plug and you'll end up fishing )
- Refit the new plug giving it a few turn anti-clockwise to make sure its not cross-threaded, then tightening it up to tight and quarter of a turn or 25 NM
- Continuing in the same manner for the rear ones replace the HT Leads and Remove the 8mm bolts on black cover on the front bank.
- Replace front plugs - easy enough since you've got no access problems. You might have to remove the 4 8mm bolts securing the IMRC
- Reconnect HT leads and double check everything's back in place and secure
- Start her up and make sure there are no misfires or sluggishness
