Just purchased a 2007 Navigator with 60k miles from AZ and drove back to her new home in IL. I am wondering what types of things I should look to "tune up" on her. I have done some reading and am hearing suggestions like...

Transmission flush and filter replacement (hearing some say do it and others say dont need to)
Fuel injector service
Fuel filter replacement
Coolant flush
Check and replace belts as needed
Check battery and replace if needed
Spark plug replacement

Hoping to get some guidance and suggestions on what to look into. Would look to do as many on my own as possible, knowing a few that I wont.

Thanks.

 

A quick Google search will turn up the Maintenance Schedule.

Coolant flush and plugs can wait until 90-100K but since you don't know how it was driven I would do them-money permitting. You got about all of them except air filter.

 

The maintanance for 60k is very uneventful. Oil and filters. That's it.

 

I'd hit the spark plugs sooner rather than later only because of the issues with them. I just did mine at 78k and only 2 of 8 came out. Thankfully I had the Lisle tool to get the other 6. $60 for the tool was money WELL spent. I wouldn't even think of doing a 5.4 without having it ready to go after doing it once. I went with Motorcraft SP515 plugs and it runs like new.
I'll wait until 100k for the coolant and tranny flush.

 

Did the new plugs make the truck idle smoother?

 

To be fair, it ran pretty smooth before. It wasn't bad. I had a hesitation getting up on the highway once in a while though. I haven't had it happen since. Now, the engine feels like it's a balanced race engine lol.. When you're parked it's hard to tell its running it's so smooth.

 

My plugs were changed less than a month ago when the truck rolled over 100,000 miles. Impossible to tell by driving. Ran well before. Runs well now. They kept the truck overnight and I believe they let the plugs soak overnight before pulling them in the morning. Truck was ready by 0800.
