Any high milage 3.7L mustangs out there. Just wondering how long the timing chain lasts, clutch (easily driven daily driver), universals?
What to expect to start failing. I just had a rear caliper replaced as it was leaking.
I replaced rotors and pads @ 80,000.
I have 108,000 miles on my 2012.

Thanks Hershey

 

Luckily, we have one of the most reliable engines that was produced for a Mustang. You can very easily make it 200K miles with good maintenance. The one weak spot that gets a lot of confusion is over the water pump and chain. If you have a Transverse mounted 3.7 with the pump in the engine you have to be really careful, because your car can go kaput in an instant without you realizing it. Most of us have the pump outside, in the front of the engine. A lot of them do go bad at low miles because of a design flaw of not having a check valve in a return hose that doesn't allows air to get into the system. It would be a good idea to check the hose, and maybe even replace it, it only takes 15 minutes to do and is a cheap part.

My '12 V6 has 71K on it, and a friend of mine just hit 150K on his with no serious issues.

 

I'll take a look at my 3.7L. Right now I have 111,XYZ miles on mine, and running fine. .Little confused about your description of the water pump variations. Traverse mounted in a Mustang?

Yeah, there is an entire thread about it here:

Maybe a Heads Up - The Mustang Source - Ford Mustang Forums

 

Transverse mount is only in the SUV with the Duratech 35, they were trying to discredit the 3.7 on a truck site I am on by telling them it had the internal water pump that the transverse mounted motors did while the 3.5/3.7 in the rear wheel drive platform had the external water pump.

 

My brother-in-law has a 2012 3.7L Mustang with over 300,000 miles on it and no major issues. He religiously changed ALL fluids and performed the required maint. at the required intervals. His miles are mostly highway miles and it's garage kept.

 

That is good news -- in a way. At that rate my Mustang will outlast this 75 year old.

I Can Relate! My 07 Gt-500 Has 34K On Her! It Should Outlive this 60 Year Old With Health Issues!

Enjoy That Car!

I have a 2014 V6 Premium and the only major issue I’ve had was replacing my power steering rack because I’m a ******* and tried to look cool but I’m not gonna get into that lol

other than that only maintenance
engines solid as a mf

 

They used the same engine in the delivery/work vans. My father has a Transit 250 (3/4 ton work van format) that he uses to make a living. It's got the 3.7L. It hauls a couple of tons of tools 24/7/365 and he puts over 200 miles per day on it many days. I can't remember his current odo reading...over 150,000 I think and he beats on it daily. He's so busy that his oil change intervals are stretched out pretty far. To date zero issues with the engine.

 

Why Ford discontinued the 3.7 V6 still doesn't make any sense... It's not like it was an old architecture, as it was still relatively a new engine which was both reliable and efficient IMHO.

 

I guess they all can't be the 300 straight six, Ford had it from 1965 to 1996. My Aunt still has some of those around in the wind machines in the Orange groves.

 

Ken, I'm not quite sure if I misinterpreted your definition or not, but neither Ford's previous 4.0 V6 and 3.7 V6 engines had nothing in common with Ford's 300 straight inline 6 engine... They're built on completely different architectures...

 

It was just the fact that the 300 Six was built for so long, was reliable and was just a darn good engine for so many years. The 3.7 is a good motor with both good power and pretty good fuel economy and was pretty dependable, kind of like the 300 but the way the EPA is now it was not good enough for the long haul like the 300 was.
Comparison made on dependability and the fact they did not give it the time to live like the 300.
Although the Cologne V6 was around in some sort from 1962 until 2011 in one way of another also but I believe it was 1990 when the overhead valve 160HP 4.0 came out

 

Thanks for clarifying, Ken... I obviously misinterpreted, just as I thought...So you're absolutely right about the cologne V6 which eventually was upgraded to the overhead valve 160HP 4.0 and then in 2013 with the 305HP 3.7 V6... I definitely agree they're both very reliable and provide very good fuel economy and really good power, just as the 300HP inline 6 had before them.. Therefore, they most definitely share the same reliability, fuel economy and good power in common by comparison...
