1989 Jeep Grand Wagoneer 5.9 from North America


With a little money and time, the most versatile vehicle on the road


Despite rebuilding the motor and transmission twice, once for the drag strip and now for cruising, I love this thing to death. It was mine and my dad's last project together. He and I were huge into drag racing and wanting to build something unique. I had already had one of these; it was an 88 and I loved it. So we bought this one and built it to run. We got the last two years of my high school running the crap out of it at the drag strip before we lobbed the cam in it and decided to put it back factory. I still have it to this day and drive it on road trips constantly.

My only problems are the gas gauge of course, and the starter sticks from time to time, and I'm having an issue with the coil getting too hot and losing fire. I'm in the middle of fixing that problem.

This thing has only let me down twice in the span of ownership. That is going to school in it and I burned up the transmission racing someone, and the most recent was in a Mexican restaurant parking lot due to it losing fire because the coil got too hot.

General Comments:

I will always own one. If not this one, then another one. It has been the best at the drag strip as well as normal cruising and off-road when I go surfing, fishing or hunting.

Would you buy another car from this manufacturer? Yes

1989 Jeep Grand Wagoneer 4x4 5.9L from North America


Something I just can't rid myself of


New starter, alternator, fuel pump, battery, brakes, disc (indicator tab fell off).

Driver's seat came split in the leather when purchased ($600).

Dripping ATF, about a pint every 4-6 months, until a cleaning with a degreaser, and now a pint every 7-10 days. Possibly the gasket or the linkage inlet above the pan (driver's side).

Rear tire blowout.

Rear window failed; re-wired myself with a relay, but it doesn't have up/down limit switch/control.

No power door locks, driver's side, and tailgate locks failed.

"Vapor lock" when really hot; possibly was the plugged EGR (which was very recently noted); waiting for hot weather to again arrive here in Phoenix.

Downstream check valve plugged, as well as a broken air line at the frame bracket en route to the cat.

Collision caused my removal of the hood lock mechanism (now being locked with a chain), and pulling of the right front corner with a tow strap attached to a parking structure beam (reverse, then into neutral about 12 times, before the "guitar string" sang aloud!)

No A/C, heater switch or cruise control.

Bad MPG (but runs great), one filler tube rusted at spout.

General Comments:

It is like the Rhino, sitting above everyone, seeing everything, and knowing there isn't a passenger vehicle out there that could kill me if I was hit really hard.

It needs lots of work to make it a true spectacle, but remains very reliable and gets lots of attention. I even had a 16 year old show me appreciation for my Lady T-Rex.

Would you buy another car from this manufacturer? Don't Know

I don't think you are dealing with vapor lock. I have an 89 Jeep Grand Wagoneer that would die in the heat. I changed the ECM module (the silver box mounted to the driver's fender well) on the advice of a Jeep mechanic, and the problem was solved.

I also have a 1989 Jeep Grand Wagoneer and am looking for parts to complete restoration. Most are electrical; I need driver's side door lock/unlock switch, left rear door lock motor, left rear, right rear and right front, regulator/motor. Do you have an outlet that might have these. Also need a rear windshield motor. Thanks for any help that you might give me.
