Heard a TON of great things about www.rockauto.com....and from a variety of other sites.

Even with more expensive int'l shipping to north of the 49th , it's still amazing the number of fellow Canadians I've heard from on other sites who regularly order from that site...so I can assume that even after duty and shipping it's still may be a great value proposition...even for us..

Often wondered if ordering things like brake pads / rotors ( of OEM quality or a bit better ) from Rockauto might make sense at all.

Great insights ..thanks !

I guess I can only hope that the guys on these UK sites have a good handle on what non-engine H/MK5 parts would bolt on to our engines and which don't......cause I'd have no clue.

Like Astra La Vista alluded to, unless you know exactly what part you're ordering, you might be at mercy of these UK sites...taking a chance they won't send the wrong part.

the OEM parts I wanted, and they had really good prices in comparison.
Did you find Quest Motor Group out in Braintree, Essex to be substantially cheaper than LMF ?

If you read the 1st post of this thread: part number is 10458316
I've also attached a link.

This is a good site. Just open a thread or PM me for part numbers - I have an Electronic Parts Catalog for Vauxhall/Opel vehicles. There is also Nalley Buick GMC that lists illustrations and part codes (and you can order direct from them). Some of the parts are not obvious and may take quite a bit of time to find if you don't know where to look for them. It is hit or miss if the dealer will give you the part numbers.

Their value was in the shipping. I don't know how, but they always had the best price quotes when it came to posting parts. I don't know if that has changed because it has been years since I've last organized a group buy for parts.

This site works: http://parts.nalleygmc.com/. There are others.

Then, simply cut & paste the part number(s) directly into the Google search engine. You might get the odd response, but if you happen to be looking for an OEM timing belt for our engines (as an example), plugging in "93180815" into Google gets you this (awww, look at the lonely little red trailer).

the cost to have the dealer replace the coilpack is $1051 (coilpack) + installation + taxes for a total of $1359 cdn. Ripoff! I said NO WAY! I told them that i would purchase aftermarket.
it is easy to remove & replace.
I ordered a new coilpack (standard motor products) from rockauto. cost is about $335 including shipping to detroit. it arrived in detroit this afrernoon. will pick up tomorrow.
LOL @ installation. They take off the plastic piece on the engine, loosen 2 screws, lift up the coil pack, replace it with the new one, tighten the 2 screws and put the plastic piece back on.

Uhhhh because some of us don't know crap about working on cars? Of COURSE it's cheaper to do it yourself, you save the labor and diagnostic costs. But that isn't always an option for everyone. Lack of knowledge, lack of time, lack of desire, having tons of money (in which case you're not driving an astra).

As for the issues described, I had all the same on mine at 78k. Needed a timing belt, ignition coil blew which blew all of the sparkplugs. Shop Quote $1500.

Now had I done it myself I'm sure it could have dropped to 5-600. But I rely on the expertise of others. And before anyone starts firing back on how I should suck it up and just learn how to do it myself, consider all the other stuff you rely on people to do: grow your food, blend the metals to build your car parts, pick up your kids from school when you can't, fix your roads, etc.

What happens to the coil pack that makes it go bad? I did my first spark plug change today (34xxx miles) and the coil pack looked good. Do the rubber boots crack or is there some electronics inside?

I am assuming you are trying to say that the interior of the coil packs do not "go bad", if I am misunderstanding you please correct me. However there are a variety of things that can go wrong on the interior of the coil pack including corrosion, erosion of the interior insulation (causing the reduction of internal resistance as you have stated), or other general internal failure.

Assumption incorrect. An ignition coil failure is almost always internal in nature -- short of an actual external housing crack or puncture. Today's coils are often buried deep inside the head where they receive very little cooling (unlike a traditional single external coil set-up that would be exposed to fresh air). Thankfully, modern coilpacks actually have to work less hard and build up less internal heat because the work of a single firing cycle is spread out over multiple coils. Still, it is almost always engine heat that eventually kills a modern coilpack. Water intrusion is rarely an issue because today's coilpacks are housed in plastic and filled with epoxy to make them literally waterproof. Contaminants building up on the outside of the coil is also pretty much a non-issue considering how buried these things are inside modern engine compartments.

Default Re: Bad coilpack, VERY expensive part

Hi Everyone, I have a 2009 Saturn astra XE and 3 months ago I had a cylinder misfire. after scanning the engine problem and reading this forum I went ahead and brought the car to a mechanic to who (as I was expecting) told me that I need a new coil pack and might as well a new set of spark plugs.

The coil here in Canada (from the dealership) is $1,100 and the cheapest I was able to find it was $800, so I decided to buy it from VauxhallWorldParts.com. These are the items I bought, coil pack #10458316 and spark plugs #0242229699. Once I got the parts I brought them to the mechanic and he installed them for $100

Two days ago, my car once again starts shaking and the engine light goes on, when I check the fault code it said cylinder 3 misfire, so I took the car again to the same mechanic and he told me that the coil failed and when he checked on the spark plug on cylinder 3 it was black.

What could have happened? did I not get the right parts? he is suggesting for me to buy again the coil pack online but to buy the spark plugs from GM ($18 each)

Help?

REWARD EXCELLENCE!

I'd contact VauxhallWorldParts.com store for refund or exchange.
maybe call them, when I had issue with my order I was able to speak with the customer support in just a few minutes.
My pack from that still works well after many miles and I got some iridium plugs from Amazon.
I'd get a cheap one for $70 from China and see how it goes. You can get 16 for the price of one from GM and I don't think it is 18 times worth

Great point, I just saw on their site that the parts have warranty but you have to send them in for them to forward them to the manufacturer and if they determine that the part is faulty then you get an "exchange" or "refund".

I'm still puzzled over what could have caused the spark plug to burn like that, could have the coil pack shorted? could it have been the spark plug that was faulty and damaged the coil pack?

The mechanic said that there are no wiring problems, but I just want to make sure that this won't happen again if I get a new set of coils and plugs.

No idea. After all, you are purchasing another GM part, could be just as defective as the one that broke

AIP Electronics has the 2008 COIL PACK for $89 US.
I had it expedited for a cost of $65 US and it came in 3 days (was supposed to be 2 days but with Customs, it was delayed).
I had to pay $12 duty on it upon arrival by UPS.
STILL saved me tons of money!!!
My grand total for this part with shipping was $190 Canadian versus the $1051 the dealership wanted. Used part $300 or an aftermarket part I was quoted $700.

SO...AIP electronics and the part is INSTALLED.

PS - YouTube has a DIY video and to replace this part took me about 10minutes because it was -10 outside and my hands were frozen.

Note to all who find this post:
Do it yourself and save the labour!!!

2008 Astra XE
Default Re: Bad coilpack, VERY expensive part

Hi All

I am a classic Cadillac guy but my daughter in law has a 2008 Saturn astra that just started misfiring. We changed the spark plugs which she informed me she has never done even though it had 175k miles.

I am new to this forum and thanks for the advice, I was hoping to get away with just changing the plugs. Needless to say they had seen their best days a long time ago.

Now I am looking at the coils. I see autozone has this at $449, Rockauto at 279 but these on Ebay are $89 with free shipping. What gives here?

I am currently in Arizona with basically no tools and I have already taken the coil off to change the plugs so I know its easy. We have an autozone a block away. They were very helpful.
