Replace ignition coils (they still work)?
Hi, I've got about 90k on my Escape.
I was talking to a mechanic, and he's recommending I replace my ignition coils (I think that's what he called them) before they go bad. He's says they'll probably fail around 100k. I have a V6, and he says at least the three in the back get exposed to a lot of heat and tend to fail.
What do you guys think? Would you replace them if they're still ok?

I think he's trying to sell you something you don't need. Ford ignition coils aren't know for premature failure (unlike Audi/VW coils that used to be terrible) and you don't read about many failures on this forum. I have 195,000 on one V6 Tribute and 100,000 miles on another V6 Escape. All have the original coils. When one goes bad you will know it and can replace it then.

Thanks guys! It's good to hear about the 195k and 200k cars. He was telling me that they could basically fail any day now, and I might get stuck in the middle of no where. Sounds like he wasn't necessarily correct. I think I'll wait for now.

Oh, please do a search on 05 or 06 v6 coil or pcm issues. Mine had 86,000 mile and had a misfire on front coil year ago(replaced), then over summer other 2 coils in front went(replaced). Then this fall the rear all had went. After doing search there is a TSB on these years where ford put in wrong spark plugs from engine plant and they feed back through coils in return kills the PCM. Well guess what happened to mine. Yes, I had to replace all plugs coils and a $800.00 PCM. Ask me if I was not pissed off.

Ignition coils
One more opinion on preventative maintenance of ignition coils ...
I had the coil fail at 100K on a 2003 Mazda MPV (uses same 3.0 V6 as Escape). Of course, it was number one cylinder (driver's side firewall) which is difficult to reach (procedure is to remove intake, just like on Escape). I replaced cylinders 2 and 3 at the same time as preventative maintenance. I also have a 2001 Escape with 3.0 with 120,000 miles that is running all original coils. At next spark plug change (likely 140-150 range), I'll replace the rear bank coils as PM. Given my history and the difficulty of getting to those back three plugs and coils and the opportunity to buy the parts in advance at a discount, this just seems like the smart move.

Interesting idea. I have just short of 200,000 miles on my 02 Tribute and am thinking that it is time for another spark plug change. Probably would be smart to change the coils at the same time. I think I will take a compression check on the cylinders at the same time.
