I've got a 2007 Jeep Compass with a 2.4 Liter I4 with a manual 5 speed transmission and been well maintained for the last 115,000+ miles. I've learned a lot on it, and it's actually a very simple vehicle to maintain. All the work has been done by me, except for the alignment throughout the years.
What I've done/keep doing:
Changing the oil every 3,000 miles or roughly 200 hours.
Change the air filter every 20,000 miles.
Replace the front and rear and every 30,000 miles suspension components -- every single part, including getting an alignment. This has been twice already and will be doing it again this summer.
Replace the pads and rotors every 30,000 miles.
Rebuilt all four calipers at 90,000 miles, including flushing of brake lines.
Replaced both oxygen sensors at 90,000 miles.
Change the spark plugs with Mopar brand every 20,000 miles.
Change PCV valve every 20,000 miles.
Flushed and filled coolant with Mopar brand coolant at 100,000 miles.
Installed new Mopar brand accessory belt at 100,000 miles.
Drain and fill the manual transmission case with Mopar brand fluid every 30,000 miles.
Drain and fill the Power Steering pump with Mopar brand fluid every 50,000 miles.
As I get closer to the 150,000 mile mark, should I be looking at replacing the following:
Coil on Plugs
Clutch and Flywheel
A little background on this particular vehicle...
It gets used around 6-7 days a week. It can sometimes average 150 miles a week, all the way up to 600+ miles a week, and a ton of idling in between. Times where it has idled for hours on end.
Is there anything else I should be doing to properly maintain this engine/vehicle so I can expect maximum service life from the engine? The chassis itself appears like it is holding up.
I'm up to around the ~7,500 hour mark on the engine, according to my scanner. What is the useful life before rebuild of this particular engine?
