Jeep Cherokee Forum
After the very last flush, I replaced the thermostat and thermostat housing just because. Out of the box, the thermostat housing had what looked to be like a polishing stone lodged in the threads. I was able to get it out without damaging the threads, but how odd... Use a 190 thermostat because thats what the 4.0 was designed to use.

New fuel filter installed. Before you start up your jeep again, you need to re-pressurize the fuel line and to do this, just turn your key to the on position a few times repeatedly. You'll hear the fuel pump whir up which it pressurizing the line.

Before you disconnect the fuel lines, you'll want to release and pressure in the system so that you don't get sprayed with gasoline. There's a little pressure release here above the fuel injectors.

It works like releasing air from your tire.

Old spark plug (Left). New spark plug (right). The height difference was concerning to me so I ended up changing them a few days later.

The tune up kit came with a little pack of dielectric grease to squeeze inside the boot of the ignition wires.

So these are the new spark plugs that I decided to go with instead of the ones that came with the kit. Bought them from O'Reilly.
