Spark Plug and Coil Pack Change

[merlinq21]

I am looking for some help and hopefully some advice.

I have new spark plugs and coil packs to install on B8- I was attempting this on the weekend and I started by trying to move the coolant overflow bottle. While it was easy to move the bottle from the two bolts; I noticed that when I tried to move the bottle, the coolant started to leak from a hose on the bottom of the bottle.

No matter what I did I was not able to stop the slow dripping leak; based on that I stopped the work as I was concerned that I had damaged the lower hose of damaged the clamp that secures the hose to the bottom of the bottle.

I did find some videos that show the step by step; however, none of them deal with the coolant leaking issues. I am wondering if the clamp is loose- I had have to have a new water pump and T stat installed about 5 weeks ago and I wondering if that hose clamp is either loose or defective

Anyone have any ideas or recommendations?

Thanks

i would look closely to see if you have a crack in the coolant tank around the nipple. I don't . you can always replace the clamp with any scew type but you are likely to lose some expensive coolant.

Thanks- funny thing is, no leak when back into place, it seems the hose or the clamp are not seated properly. Coolant level is bang on. Having said that; will check it out- thanks

Perhaps by putting the coolant reservoir back to it's original place, the ever so small crack by/near the hose nipple may have sealed back up to the point you don't readily see anything leaking. However, after the engine bay reaches operating temps and you put a few miles on it with the associated vibrations of that driving, you may notice a slight drop in coolant level.
Safe to say that the coolant reservoir sits too close to the engine in my opinion. This close proximity can easily lead to the reservoir's plastic body becoming brittle like any other plastic exposed to numerous cycles of hot and cold and thereby be fragile enough to crack when normal maintenance is performed and it has to be moved.
As a precautionary measure for my old A4 b5's 2.8L coolant reservoir, I replaced it with a newer one just on spec simply because of potential issues like this.


On another note, what coilpacks did you use as replacements? The R8 ones - 06E 905 115E ?

Thanks for the feed back - worth a look this weekend.

I bought the coil packs through amazon- not sure what the quality is like but will give them a try and see - I have the stock ones as a back up.

Coil packs see below- amazon.ca shipped from Vancouver seller - Tyeeimports
