100K Maintenance

[Bullitt_Will]

Hi all! Just wanted to get an idea of what parts I need to be conscious of looking to replace soon.

I own a 2019 Bullitt NA. Currently has 81K miles on it. Just recently had the struts and shocks replaced at 75K miles. It’s on its second set of tires. Most likely will get new ones soon. I love this car, and I want to get ahead of anything that can fall apart soon, cooling, radiator, spark plugs, timing chain, pumps etc.

Any advice would be appreciated. Thanks.

I don’t think there’s any real issue with timing components at that mileage. I’ve replaced a timing chain set and cam phasers on a 2005 4.6 when it had 150k on it and that made a huge difference. The coyote might be different longevity wise.

The two easy ones I’d swap out are brake fluid and coolant. They’re easy and you’ll help prevent corrosion. Brake fluid should really be done every few years as it’s hygroscopic and pulls water into the system over time. Hot brakes and water in the fluid is no bueno. I use a pressure bleeder like the motive one and 2 bottles of fluid. First change is $75, every one after that is an easy $20 worth of fluid and an hour of your time.

The coolant just plain wears out with heat cycling. I’ve got an airlift system but you can dump most of it and add in new 50/50. It’ll take a while to burp the system though.

Inspect car. Replace things as needed.

Check all the suspension, subframe, and diff bushings, I had a number that were torn or cracked at that mileage.

Fluids.

Check the coolant reservoir, mine was crumbling.

Check the coolant hoses, belts.

Basically anything rubber and any critical plastic parts exposed to heat.

I've recently done my 60,000 mile maintenance even though I'm right at 56,000 miles. There are several things that I did just to be sure I'm good. What triggered some of it was my water pump was beginning to leak so I started with that.

Since I had to take off the belt to get to it I knew that I'd just replace it with another belt and while I was at it, I replaced my belt tensioner pulley and inspected all of the other pulleys.

My full list of everything that I did is the following:
Water pump
Serpentine belt
Tensioner pulley
Oil with full synthetic and filter change
Spark plugs
Cleaned the Mass Airflow Sensor with MAF cleaner
Cleaned the throttle body with throttle body cleaner
Cleaned my engine air filter
Replaced my cabin air filter
Fully flushed my engine coolant until it was clear distilled water coming out and converted from orange to yellow coolant
Bled brake lines with new Dot 4 brake fluid
Changed my MT-82 transmission fluid
Changed my rear differential fluid
Inspected my hoses
Fuel system cleaner
Changed front and rear brakes (Rotors and Pads)

I did all of this over a weekend doing mainly the top of my engine one day and everything on the bottom of the car the next day.

I took it to a shop for a suspension inspection and to have them change out my Struts and Springs. I went with the Ford Performance Struts and Springs.

I also got brands new tires since I was approaching the wear bars. I went with the Continental Extreme Contacts for this round of tires.
