Ok, so I’m coming up on 90k Miles on my Mustang GT (currently sitting at 86.5k).

So my question.....what maintenance should of been performed by now? Like I’ve always change my oil and such regularly and had the inspection by either Goodyear or Firestone. So far the only thing to come up is I am about to need a new battery.

My question is...should I have done other preventative maintenance by now? Also the brakes have never been changed but I’ve had them inspected on the last oil change and I’ve still got 7mm left on my brakes.

Should I check all my fluids soon? Like do a full flush and do a fresh fill on everything? Also how about suspension and other components?

My father is a stickler and I don’t have all the tools required to do the work myself nor the talent unless it’s the Gran Torino, because simplicity of the design.

Anyway what should I do maintenance wise?

Check the car’s service schedule.

I’d probably do rear axle fluid, coolant, and plugs.

Manual or auto? If auto, has the fluid ever been changed? If not, what does it look and smell like?

Owner’s manual. Regardless, I like to do things early so I would probably do spark plugs, coolant, diff fluid, and trans fluid/filter.

At that mileage, all fluids should have been changed at least once. Engine oil is the most important, but I’d also change the diff oil, transmission fluid/gear oil (depending on whether it’s AT or MT), coolant, power steering fluid, and brake fluid.

Brakes don’t need to be replaced until they’re actually worn, so if they’re still good, don’t worry.

Suspension bushings, balljoints, tie rod ends, sway bar links, and shocks/struts are probably kind of worn by now, but it doesn’t really require replacement until something is broken.

You have almost 90k miles and have never needed new brake pads? Holy crap. The longest I’ve ever been able to go was 70k, and that was in a car that barely had enough power to get up to cruising speed so it wasn’t like I had to use the brakes a lot.

What’s your opinion of doing an auto trans pan drop and filter vs. a flush at this mileage?

And if you don’t have the maintenance schedule, you can find them on the Ford Owner’s site.

I don’t know if yours is a 2010

or a 2011

I’m actually getting a filter/flush right now as a precaution (suspected to be done 10k miles ago but tranny was empty and had to top her up a couple weeks ago) haha. I’m sitting here watching it be done haha.

99% of the time I just do pan drop and filter. The caveat being you just don’t get all of the fluid that way. I don’t have a problem with flushes, as long as they’re done correctly and regularly, but the filter should always be replaced at the same time. That being said, a flush is more likely to knock free a bunch of gunk and get it stuck elsewhere and/or remove all of the friction material floating around in the fluid that is keeping everything going.

If done correctly and regularly neither a flush nor a fluid/filter service will cause issues. But a flush is more likely to reveal issues that were being hidden with old fluid.

80k miles isn’t that high and unless there are symptoms indicating potential issues I wouldn’t worry too much about it.

Thanks!

remove all of the friction material floating around in the fluid that is keeping everything going.

This was my understanding as well; in a high mileage car or truck that could make a functional trans start to slip.

Auto, and I have never check the smell. I’ve only sniffed the Gran Torino’s fluids

The car was in my dad’s possession for the first year we have owned it and it does mostly highway miles. Granted some reach VERY high speeds but I don’t stomp them to slow down I bleed off speed by letting it wind itself down with light brake application.

I have the auto, I’ve also only ever have changed the engine oil and nothing else. Suspension doesn’t creak or anything yet but you think I should still check it?

Yeah but there’s no way of knowing if that trans was going to start slipping even without a service. I suspect it would, even if not quite as quickly as after a service.

It’s worth the few minutes it takes just to take a look, but if it’s driving normally and not making any noise/clunks/vibrations/pulling to one side, then I personally wouldn’t consider it a high priority unless I was going to be working on something in the area anyway.

Hey I know you deal with AMGs but how much longer do you think I should push my cars stuff?

As far as maintenance goes? Check the recommended maintenance schedule and try to be a little early on whatever it says. Or just go ahead and do whatever hasn’t been done yet at your earliest convenience. You shouldn’t feel the need to rush to get anything done. Just do one thing here and there if that’s what you need to do. I would probably start with the trans service, then brake fluid, just from a reliability and safety perspective.

Well...it’s had nothing done sense we have bought it a few years ago. It’s gone 66k miles under my familys ownership, keeping track with a second trip odometer, so I think it may need some looking over.

I agree with owners manual checking for starters. then go from there. don’t go overkill like the Motorhead song. :P

It does need a good refresh I know for sure it’s had 0 scheduled maintenance done for it’s millage.

spark plugs.

air filter

fuel filter (possibly - if not part of pump assy)

cabin filter - if fitted

drive belt- check for cracks.

coolant

brake fluid - every 2 years regardless of miles.
