Coilpack connector. Subaru Forester

[joefraser]

The car died at a set of lights last night, turns out to be the 4 pin connector on the coilpack had a little corrosion in it on the lead side which the road side assistance tech cleaned on got me on my way again.

Finding a replacement plug is proving to be a pain, I've found something on amazon which looks the part but I'm not confident it's correct.

Any help or suggestions to source one?

Which year/engine?

[joefraser]

It's a 2004 2.5 litre non turbo. It's an Australian car which I imported.

I can't see the plug I need on there but I'll give them a call.

Cheers MDMA.

what about keeping with original plug and giving it a good clean or is it really toasted , it sounds like it is still working

[joefraser]

The roadside mechanic cleaned all the copper contacts and gave the inside a clean out which is what got me on the way home again. My concern is with how damp it is up north it isn't going to be long before it happens again on a plug which is letting water in.

Replacing the plug is a longer term solution I hope.

option 2 is a suitable grease , if the rubber sealing part of it is gone then i understand if not i would clean grease put back but with out a photo i don't know more

Joe, go buy some di-electric grease to cover both internal and external parts of the connector - any good motor factors/RS Components can supply. The grease will act as both superb insulator and weather protector for the connectors. You could also use Vaseline/petroleum jelly...but some forms of rubber don't like Vaseline and it causes the rubber to perish. And whilst doing one coilpack, why not clean and re-grease the others and any other electrical connectors that look like they need a spruce up...just remember to disconnect the battery -Ve before starting the work.

I'll grab a photo of the offending plug this afternoon .

Thanks for the assistance so far

That be the plug

based on it being that plug all day long for me would be clean grease and put back on , a long time ago marigold gloves were cut down to fit a distributor you could try some thing like wise if you are that worried , the chance of you improving a plug that looks structurally sound by changing it is not good so work with what you have

[joefraser]

Heading out to halfords now to get some of the recommended grease, will fit the new leads when I get home to I think.

After another bout of particularly wet and windy weather the issue has hit the surface again and the car is cutting out a lot, left me stranded last night on a dual carriageway.

Trying to source that plug/harness is proving to be impossible, shipping one from Australia is an option but it's super expensive and slow!

Does anyone know if this is a part shared with other models? Subaru are notorious for having bits from all kinds of models all over the range so hopefully someone knows of a solution.

It will probably be shared with another model somewhere, have you tried Www.opposedforces.com to see if you can locate the part number & cross reference it ?

May be worth giving www.importcarparts.co.uk a shout, if they don't have it or can't get it they are usually pretty good at pointing you in the right direction to get one from

any chance of a photo to see what you are trying to do plug wise

sorry i can't seem to open that can you try again

[vxr2010]

sorry ignore my last got it now , are you just looking for that plug , and that plug has poor connections in it or is it the coil plug that is the issue , when ever some thing is repaired plug wise there is always a risk of corrosion etc , options are take plug to pieces and give it a real good clean plus clean coil pack connections , if you can't take it to bits do the best you can as is , then put some conductive grease in it , that is what i would do then cover it with something waterproof like a cut down marigold glove , option 2 is solder connecting wires straight to the coil and do away with the plug , i would only do that option if 1 does not work , as in the long run a clean dry greased original plug is best option against crap weather

Tried importcarparts, no replacement plugs available- full loom only... £800

Don't want to take it to that degree really but will if I have to, for the sake of a perished plug it is an absolute killer.

Watched a video on youtube on how to replace the plug, common fault relating to age and going through numerous heat cycles etc. The plugs are available as a kit from the states, that might be the next option.

Sat at an auto electricians now trying to make best with what I have, it's a nightmare as I absolutely need the car for work!!!
