Hi all,

 

I'm hoping to start a thread to put everyone's mind at ease over the 1.0 EcoBoost engines.

 

I wanted to list the known problems and the along with that, list the preventative actions as well as remedial if problems exist.

 

So here goes:

 

Engine failure

Caused by-

Head cracking - caused by engine overheating.

Engine overheating - caused by loss of coolant

Loss of coolant - caused by:

--Degas hose split

--Coolant tank micro cracks

--Water pump seal leaking

So prevent the latter to stop failed engines?

Preventative action:

Replace degas hoses for mk3.5 spec?

Replace coolant tank when starting to discolour?

Replace coolant tank cap when tank changed?

 

What other know engine issues are there for these engines?

 

Thanks.

Been a few where the oil strainer blocks up causing low oil pressure putting oil light on . No definitive answer to cause but possible low quality cheap oil .

Fix of sorts is sump off and clean strainer.
