Granatelli Coil Connector Install *DUW*

[MM2004]

OK, I had to try this myself and share with the group as it is honestly quite a simple install/upgrade.

Make sure and remove the coil cover in such a fashion that will not damage the gasket on the cover, or displace it.

http://www.mercurymarauder.net/showcase/files/2/9/8/9/Coil_CoverGasket.jpg

Carefully lift one of the coil/boot assemblies from the spark plug cavity paying attention not to pull anymore than necessary on the wiring harness. (I used my other hand to bend the rubber boot when removing from the spark plug cavity, making it a little easier).

Seperate the wiring harness by pressing on the top tab while pulling the two halves away from one another.

http://www.mercurymarauder.net/showcase/files/2/9/8/9/Coil_Wire.jpg

Remove the rubber boot from the coil pack by rolling the rubber down and away from the coil pack. This was the hardest part and took the longest. While the rubber was rolled away from the coil pack, use a twisting motion back and forth while pulling, and it should finally break free, exposing the OEM spring.

Carefully twist and pull the spring closest to the coil pack until it comes free. (The spring will more than likely bend upon removal as they are very weak). You will then be able to see the 'tab' that holds the connector in place.

Place the Granatelli connector over the 'tab' and press on. (This is a tight fit. Make sure it is on all the way seated).

Slide the boot over the connector ensuring the coil pack and the boot mate together as shown:

http://www.mercurymarauder.net/showcase/files/2/9/8/9/Coil_Boot.jpg

Replace the wiring harness back onto the coil pack making sure it is fully seated. (You should hear a 'click' when seated correctly).

http://www.mercurymarauder.net/showcase/files/2/9/8/9/Coil_Harness.jpg

Carefull locate the boot end into the spark plug cavity until you feel it touch the end of the spark plug. Now, I had to press using quite a bit of pressure until I heard the connector 'snap' onto the spark plug. (I made sure my thumb was centered on the coil pack and placed my other thumb over top using both hands to press).

It appears the Granatelli connectors are shorter than the OEM. Once installed, the coil packs do not seem to stick up as far as with the OEM connectors.

http://www.mercurymarauder.net/showcase/files/2/9/8/9/Coil_Seated.jpg

Inspect the coil cover gasket ensuring it is fully in place on the coil cover before replacing onto the cam covers.

It may be a good idea to ensure the bolt holes of the coil covers line up with the cam cover bolt holes before resting in place. (Worked for me).

Tighten coil covers appropriately.

I truly hope this helps everyone that has either purchased these connectors, or are thinking about purchasing them. Previous installs may have received some negative feedback. But I can assure you, this is quite simple for anyone to do themselves.

Best,

Mike.

Great post! I hope to get my Granatelli Coil Connectors on this weekend. Thanks for the install tips and pics:beer:

[MM03MOK]

Great pics, nice and simple instructions! Thanks, Mike! Another great addition to the Reviews section too!

[MM2004]

Thanks Mary and Mike!

I have to thank Mac for making himself available while doing this. I did have a couple of questions, and his experience helped me along.

Mike.

[Tallboy]

All my questions about this mod are now clearly answered. Great Job, Mike!!! :beer:

[SergntMac]

Nice job, Mike! Great pics too.

[jimlam56]

Mike, your pictures pointed out how much more substantial the replacements are over oem.
I feel better just knowing the "ball point pen springs" are no longer a vital link to my spark plugs!
Did mine during the last group buy, about 5k miles ago, and highly recommend this mod.
It truly is a no-brainer!

[KillJoy]

Nice write up Mike! Glad to see it isn't that difficult. Perhaps this weekend ???

Wow Mike!
You've been Published!:D

[O's Fan Rich]

Cool! I got mine yesterday. They went into the pile o' stuff waiting to get put in when #132 arrives. This is a great help!!!

[Rider90]

Seeing as so many of you are doing this, that leaves 8 OEM coil springs for each person. How about mailing them to me? It could help in my troubleshooting. Please, only non-damaged ones...PM for address... thanks to those that are helping me out. I need to drive my Marauder, I'm going through withdrawl...

[MM2004]

A few more details:

I did not use the dielectric grease. I was pleased to not see any evidence of moisture and simply did not see the need.

The rubber ring on the Granatelli connector was left near the center prior to installing the boot.

Removing the OEM connector from the spark plug has little to no resistance due to loose fit. You WILL know when the Granatelli connectors are seated onto the plugs. Major difference over the OEM as the pics show.

I will give a comparison on driving/SOP when the weather is good and I can wash the MM. I will not drive her in the rain nor when dirty. :o

The engine bay could use a good wash too.

I got mines today.. OBTW- that piece that your describing is a ferite choke.

[fastblackmerc]

Just an FYI. You might want to add a little silicone sealer to the the coil cover where the wiring harness exits (right side of coil cover in first picture). I agree this is a "no brainer" mod.

[MM2004]

Forgot to post driving experience after the install.

I cannot feel a performance gain during medium and WOT.

However, the idle feels smoother and a little more responsive when tapping the throttle.

Knowing all of the spark is making it to the plugs, is enough for me.

Thanks,

Mike.

[RF Overlord]

Mike, my experience was similar to yours...I can't say for sure the motor runs any differently, but I like the "peace of mind"...

[fastblackmerc]

Same here...

[metroplex]

The coil covers are a neat idea, too bad Ford didn't do something similar for the 2V engines. It looks like it'll block out dust, water, and other gunk that can short out the coils.

[Ricka11]

I did not want to mess with installing so I had a Ford Dealership install them for me in Northern VA. I had a slight hesitation going from 25 / 30 mph range before trans would shift which has gone away since the install. Very happy! The tech was able to save 3 of the stock coils so if anybody wants them, I will be happy to mail out to you. First come, first served.

I did not use the dielectric grease. I was pleased to not see any evidence of moisture and simply did not see the need.Mike, I missed this the first time around...the dielectric grease is not really there to protect against moisture intrusion, it's more to prevent the boot from sticking to the plug. Unless you plan on leaving the plugs in for a very long time it may not be an issue, but if you do pull them anytime in future, you may want to put a little dab in there...

RF,

Are you sure the grease is for that purpose?

My impression was it being used where the connector snapped onto the coil terminal and spark plug tip. :confused:

This would act as a barrier for corrosion, etc.

Mike.

[SergntMac]

My impression was that dielectric grease really isn't necessary at all on a Marauder/Cobra/Aviator, because (supposingly) we have water tight coil covers on our unique engines. I got it, but didn't use it, because I thought that it had been added to our kits because these kits fit other applications without coil covers. Use it, don't use it, whatever floats your boat.

Ummm...Wondering how that "miss/stumble" thingy "after the install" problem worked out. Anyone know the resolution?

Hmmmmm... Now that you mention Stumble , after install my engine stumbles between 1500 and 2000 rpm then clears up as the rpm climbs. anyone else started to have this problem or has this problem ???:confused:

[RF Overlord]

Mike, although the grease certainly will help protect against corrosion due to moisture, that's not it's primary use. I've been putting a small film of grease on the spark plug end of every wire set I've ever installed for the last 30 years. It makes removal MUCH easier, especially where the plug boot is hard to get at. The grease helps ensure the boot doesn't "weld" itself to the ceramic insulator of the plug, so there's less chance of ruining the wire trying to remove it. In the case of a motor with COP (like ours), it's probably less of an issue, but I'm an old dog...

[CRUZTAKER]

Great post! I hope to get my Granatelli Coil Connectors on this weekend. Thanks for the install tips and pics:beer:

I concur!

Quite nice Mike.

I should need to install mine as well at this point.;)

[MENINBLK]

I installed my wires about 2 weeks ago.
I was surprised to see that most of the OEM wires were OVERHEATED
in the upper half of the coils closer to the ignition coils.
I installed the wires and boots using the dielectric grease on BOTH ends.

I am very happy to have the same experience as everyone else.
My idle is much smoother and so is revving the engine.

I can now accelerate quicker using just a gradual push on the accelerator
without having to kick it down a gear.

It was a big improvement for me.

I was also pleasantly surprised to find all 8 spark plug wells dry as a bone.

[SlkMerc]

Thanks for the advice, I inspected the boot and there didnt seem to be any apparent abnormality, no arcing etc. I swapped the #8 with the nearest one and started the car, no check engine light on at this time. I will keep an eye on it

No. Only fits dohc engines.

[glassman99]

Sorry boys, the connectors do about EXACTLY jack. You might "feel" good but reality is "prove it". There is nothing wrong with the factory cops, connectors or other. Been there done that. Back to FACTORY and making 674 RWHP. Period.

[Quickvic30]

I installed some of solid connectors and noticed smoother running engine and a little better throttle response :)

Yes, I have them on my 01 vic.

heres a link, they come with cool blue boots too :)

Note, if you can not figure out how to install these you should not be modifying the car in the first place. :D
