Just bought a car a week ago and now it has coolant intrusion… what do I do

It drove perfectly when I got it and up until now. I really liked it but now I’m stuck with this issue.

This should be pinned in this forum as a reminder to avoid buying Fords with ecoboost engines that are prone to coolant intrusion.

That would help but there’s no clear info on which engines are affected or the build dates.

@Briar
That’s the problem, they all seem to have this issue and there’s no real fix. It’s a design flaw. Ford keeps issuing TSBs but the problem isn’t resolved. The engine is no longer made in the US, which says a lot. If it was reliable, they’d still be producing it like the Coyote or Cyclone engines. These engines just aren’t built for high mileage. If the coolant intrusion doesn’t kill it, the oil pump belt or fuel pump might. This forum will likely see more posts about failed engines and people stuck with huge repair bills.

@Kamila
I’m glad I have a diesel Fusion with the unaffected DCT Powershift. The engine is solid, though there are other issues like the water pump or EGR.

Education is easy, but learning is hard for some people.

@Briar
I think there are TSBs for some of these engines.

The problem is it’s only for some, not all.

I contacted Ford directly through their website. They said they have no plans for a recall even though it’s their design flaw. The rep was quick to end the chat. If you sell it to Carvana, I’d delete these posts to avoid any issues. The only fix is a long block replacement.

Short block*

Is there a long block upgrade?

No, there’s a redesigned short block. I’m a Ford tech and work on these engines a lot.

Was this a private sale?

It was from a small dealer. I signed an ‘as is’ agreement, but it was in great condition with no issues or warning lights.

Even if it’s sold as is, check your paperwork. There might be a clause allowing you to return it within a certain time. It sounds like the dealer knew about the issue and didn’t disclose it.

@Melanie
I don’t think they knew. The previous owner might have, and it just sat on their lot until I bought it. It was fine until the sealant they used started to fail.

Lemon laws might still apply even if it’s sold as is.

@River
That’s not how lemon laws work.

I stumbled on this post and didn’t realize coolant intrusion was common in Fusions. When it happened to me, I argued with Ford and got them to cover parts, but labor was still $3-4k. The dealership was short on techs, so I was without a car for 6 months.

@Sawyer
How long ago was that? Did you buy it from a Ford dealer?
