My GT just ticked over 91K and I've got to keep it for the foreseeable future. (I get a wilting side-eye from SWMBO when I mention getting a new one.) As it approaches 100K what areas should I look at or "no kidding-you've got to swap that out." Just had an oil change/tire rotation last week and brake pad life/rotor condition are not an issue. I'm pretty easy on my machinery.

 

Fluids. Brakes. trans, rear end and coolant. I'm in the same boat you are. My'12 has 95k and still runs strong.

 

Check/replace serpentine belts. Coolant hoses may be due. Manual calls for spark plug replacement at 100,000 miles so it can't hurt to get that out of the way. Spark plugs are really easy on 197 series cars with the 5.0 Coyote engine if you want to DIY. Just make sure to protect the positive battery cable/terminal from an accidental contact when doing # 4. Check ball joints and tie rod ends for wear. Have the shocks and struts ever been replaced? If not they are probably due. Most modern cars seem capable of at least 200,000 miles before major repairs are needed. Based on my experience with SN95 and SN197 series Mustangs these are really pretty tough and reliable cars. Obviously the more options any car has the more things there are that can and probably will fail at some point.

 

Thank you, all. Every point makes perfect sense. It still runs like a champ.

 

All he said makes sense and would agree. However, I'm at 142k and 8 years old on mine and the belt and hoses are all still original and in great shape. I've asked the dealer about replacing them multiple times and they always tell me not to worry about them.

 

Thanks, Kyle. Maybe I'll take it by my neighborhood mechanic and see what he says. I prefer to get on top of it before something fails comprehensively.

 

Just a quick update: I had the local fix-it shop look it over and past experience has showed me that I can trust their pricing and their work. At 105K miles I had them replace both front hubs (pulsating sound developed in the front end especially in turns-bearings about to fail), went through and did an entire cooling system service (water pump, thermostat, hoses and belts), transmission and differential service, shocks and struts replaced all around, rear wheel seals, all spark plugs replaced, drain-flush-replace brake fluid, front brakes done. (The last was the biggest issue-part supplier sent 4 brakes rotors-3 were one size and 1 of another-all of them the wrong size. Stretched the process out another day that we weren't expecting.) Luckily in California auto repair is considered essential activity otherwise I was fearing it would have been left in partly assembled condition for weeks. The entire thing wasn't cheap but now its good for at least another 100k. Cheaper than a replacement. I just haven't been able to let it stretch its legs.....

 

Aren't the cam chain guides a wear item that should be replaced? Not sure . . . I guess in some cases they last a long time, but if they go they can cause a lot of damage.

 

First I heard of it. A little late now but I keep up on maintenance so I can only hope for the best. Finally took it out for a freeway drive and it was noticeably smoother. Gee, thanks. Now I'll have another "mind worm" burrowing in the back of my mind.

 

sorry about that, LOL . . . I think they might not be due until 150K and even then not sure, so don't let that worm bother you too much just yet
