2007 Ford Focus 1 6 Core Plug Replacements

[@manjindervirdee1092]

Just changed the core plugs on my sons car this morning. Used a little bit of Dirko HT sealant, hopefully will do the trick. Core plugs were leaking just a tiny bit. As the engine heats up, the coolant evaporates, and because that area is pretty much sealed, the steam interfers with the HT leads/spark plugs, causing a misfire.

Good.job mate., it was an easier job than I antict

[@GregoryMcFalcon]

Does it cause an engine management light to come up? My focus has an intermittent misfire under load but no warning lights at all

[@cgi2751]

Did you have to drain out any coolant before you started.

[@HenrysGarage]

No, but I needed to clear the fluid that was sitting above the plugs with a syringe and sponge the paper to dry it

I'm assuming this ultimately solved the problem with water in that area?

[@HenrysGarage]

We've no longer got water collecting there so I think it is sorted

[@ChrisFEJackson]

Just goes to show how cars should be used frequently. I am quite surprised how much water got into that location! for a modern car.

[@HenrysGarage]

Heck, when I saw it I thought it was something far more serious. It took a little research to discover the cause

First of all, thank you so much for taking the time to make this video! Lifesaver! Do you know the size/model of core plug? I am having some trouble finding the correct dimensions for this engine. Thanks!

[@HenrysGarage]

Hi, I couldn’t work out what size to buy because there seem to be many different specs so I went and ordered from a ford garage who based it on the license plate

[@mazzus1]

@@HenrysGarage Ok, I will give that a try as well :) Thanks!

You should have thoroughly cleaned around the apertures and used some sealant in there for longevity.

[@HenrysGarage]

Good thought. Fortunately it is cheap and easy so if I see the issue persist I'll do that.
