Just had a rather disturbing conversation with one of the shops we supply over in the UK. Turns out that there have been issues with the oil coolers getting cooked due to its proximity to the passenger side catalytic converter. When the RHD Mustang was designed, some bright spark at Ford relocated the oil cooler moved it from the front of the engine, where it usually sits on the US Spec s550, where your steering box now sits, and mounted it to the passenger side of the engine very close to the cat. Because of this there have been reports of the coolers cracking and leaking oil, all the way up to completely failing and draining the engines dry!!! Ford UK have now reportedly replaced four 5.0 engines, and 1 poor soul was reportedly filmed going down the road with the front half of his car in flames!!

If you have an s550 GT please be aware of this!! It's not a scare tactic or a sales pitch, just want to make sure you are all safe!! There is a shop in the UK working on a relocation kit for this problem as we speak. When I have more info on it I will pass it along!!

I would assume then there will be a recall and fix

You're probably right. But if it's anything like the intercooler "fix" they did on the 11-12 EcoBoost F150's...I would still be a bit worried.

Hi Guy's, my first post here and I was just reading about a S550 owner on the S550 Australia Facebook page who had his Oil and water mix a couple of weeks ago. Turns out it was the cooler mentioned in this topic but a different issue. An internal failure meant the oil and water mixed. He has just received the car back and this post was mentioned.

It seems odd that the aftermarket are working on a fix and Ford seem to be silent on it here. I've had mine for almost 4 weeks so it is something I will definately be looking at as apparently the loss of oil is not picked up by any sensors until the engine is dry.

Just a guess, but aftermarket have a sales or profit motivation. For Ford it is a cost control issue*.


And a ginormous one, if Ford issue a recall they and retrofit all non-US 5.0's, that's probably of millions in costs, at the very least.

Late response to this article but I was justcsearching mustang oil cooler issues and this chat came up.

We have had this exact issue.  Oil cooler failed on Tuggeranong Parkway in Canberra,  I became aware of the issue as the car was trailing smoke - oil was leaking  (rapidly) out and hitting the exhaust, hence the smoke (got some nice  video of this leak from under the car if anyone wants to see it).  Ford in Canberra also found that the oil cooler had mixed water and oil including into the engine.  This Required a new engine.

We have had a total of 4 breakdowns in 12 months.  Main power cable shorted on exhaust,  top radiator hose has blown off twice and dropped all the water,   The last failure was on a 5km drive.

This is the most unreliable car i have ever known and its got 10,000 km on it.

Another Canberra mustang had the same issue.

Check Canberra Mustang Facebook page for discussions onbthis issue.

There seems to have been a similar problem in the US. I have found that on 26/10/16 Ford USA recalled 6582 S550 Mustangs about the oil cooler. Apparently, a hose may separate from the cooler causing an oil leak and having the sort of effect that happened to you in Canberra.

They recalled 2015-2017 Mustangs manufactured 24/2/15 to 30/8/16. They say in the recall that as a consequence of the hose separation "a sudden loss of engine oil may cause engine failure, increasing the risk of a crash. Additionally, an oil leak, in the presence of an ignition source, increases the risk of fire". This seems to be what happened to the guy in the UK.

Therefore, in view of the US recall, a few experiences here and in the UK - has anybody actually raised the issue with Ford Australia and if so, what has been their response?

Just for posterity.... adding my comments here.

Mine is  January 2017 build (delivered May 2017) - and the oil cooler failed last week of Feb 2018, with less than 9,000kms on the clock.

External and internal failure, with oil and coolant mixing and spewing out from beneath the car. Currently getting a brand new engine fitted.

Clearly the Ford technical service bulletin issued NOV 16 indicating the problem is only with vehicles built to the end of JULY 2016 needs an update in respect of affected vehicles.

https://ford.oemdtc.com/2604/oil-leak-from-engine-oil-cooler-right-hand-drive-2016-2017-ford-mustang

" Some 2016-2017 Mustang GT right hand drive vehicles equipped with a 5.0L twin independent variable cam timing (Ti-VCT) engine and built on or before 26-Jul-2016 may exhibit an internally and/or externally leaking engine oil cooler that may result in an overheating engine, engine noise, base engine damage along with an external oil leak."

See two data sources below, one from Australian media (Jan 23rd 2018), the other from CJ Pony in the USA -

Motoring confirmed after speaking with Ford AU - "NO RECALL"
