Good video! Been a few years since I did mine and wanted to make sure I didn't forget anything. More WJ 4.7 videos would be awesome!

What happened to protect tetanus? What about the do your own regear series? I don't remember ever seeing those get posted.

I just so happen to own a WJ and I know lot's of info about them! I need to do a SYE for the rear and then adjust the control arms accordingly. Would love to join the BleepinJeep team

Nice vid, I was wondering where you have been.

Freakin' Jeep & Toys Garage says:

You Bleepin Jeep Guys do a great job with your Jeep stuff and some universal topics. Keep up the good work!! For a little FYI,  WJ is 1999 – 2004. ZJ is 1993 – 1998. WK is 2005 – 2010. WK2 is 2011 to present 🙂  Grand Cherokees are my forte.

Kevin Knabe says:

I hope it didnt overheat. That's death for a 4.7.

Doug Yankunas says:

Anyone have a link to a Jeep WJ with a LS swap ? I have a mint 2003 WJ , 4in lift, 32's. The engine is toast and I'd like to swap it out for a LS. I live down the street from a junkyard , so plenty of parts there for the build including motors for cheap. Links or ideas ? Thanks

does it matter were the check ball is? i just installed mine.

dwillis says:

Finally a WJ! Too bad it's just maintenance and not a build video.

Daryl Kornbau says:

have a 94 zj 4.0, just replaced a thermostat last week. not too difficult but loosening the eight or nine bolts that you need to loosen to get slack on the serpentine belt was a pain. a couple of those bolts are somewhat hidden.

OblioAndArrow says:

What isn't awkward on a 4.7? Haha
Especially the WK…

KJM Garage says:

Man I have the 4.0 WJ and had to change the thermostat and I thought it take a hour a most and some how it turned into a 3 day repair.

SateenDuraLuxe says:

YAY! Finally some WJ content.

George R says:

Who is this guy? Oh never mind it’s been awhile. Good video Tyler

Dan Hambrick says:

Should of used Zerex G5 coolant.That is what factory calls for…

Sean K says:

Added green coolant but overflow was orange coolant?

Dennis Straight says:

99-2004 98 is still zj☺

Rabble Peasant says:

Did you just mix traditional anti-freeze and the new orange stuff?

1 MAN ARMY Guzman says:

More repairs on the wj 4.7! Good video… radiator and radiator fan? AC compressor? Tie rods?

Tyler Ward says:

Please do more videos on the WJ. Especially with the 4.0

bgtx says:

Should do a video on how to replace the transmission in the WK2.

P Ferris says:

It's odd to me that the thermostat is on the bottom hose outlet, mind you, I'm used to older gm engines and the good old 4.0. I'm interested in seeing more on the 4.7, and on the WJ. ☺

Or if your VIC (vehicle information center) dies and doesn't work.
