1989 Jeep Wrangler Window
There's something satisfying, if not comical about going through a vehicle and finding hidden treasures and (sometimes) scary modifications. In this case, the YJ had a newer Bestop Supertop with optional sliding glass uppers. Since it also came with the standard zip-up door uppers, I sold the sliding ones for $200 bringing the purchase price down to $300.

1989 Jeep Wrangler Cup Holders
This is easily the filthiest vehicle I've ever purchased. Old food, spilled Starbuck's foamy sugar coffees, melted and congealed makeup, dog and human hair; if it makes you say "yuck" it was in there. Day one would involve nothing more than cleaning sconge and killing vermin.

1989 Jeep Wrangler Speakers
In the back, a previous owner had added some decent 6x9 speaker pods to the rollbar as well as some 12 volt household lights affixed to a sweet piece of '70s wood paneling. A partially delaminated Firestone tire thrown in the back seat stymies the action in Disco Stu's electric get-down chamber.

1989 Jeep Wrangler Amp
It's only a Sanyo, but a free stereo amp is a free stereo amp. Too bad a thief had ripped the head unit forcefully from the dash. Still, the wiring is done and the amp is installed, so I'll keep it providing it works when I throw a marine head unit in. Note the dog hair-encrusted Berber carpet in the cargo area. I unceremoniously ripped it out and shot for the trash can.

1989 Jeep Wrangler Interior
Despite looking like it had never been wiped down, the interior was actually in fairly good shape. The original seats had been covered most of their life, so they were only dusty. The driver seat isn't even crushed or ripped. The carpet had seen better days.

1989 Jeep Wrangler Seat Cover
In an effort to avoid scabies or any other nasty contaminants I ripped off the seat covers, carpet, center console, and anything else that couldn't be scrubbed clean. Then I pulled the drain plugs from the floor and gave the factory vinyl seats, rollbar padding, and floor a thorough scouring with automotive-strength detergent and a garden hose.

1989 Jeep Wrangler Under Hood
I don't know where the chick had this thing parked, but the entire undercarriage and under hood was one mass of cobwebs. I liberally sprayed down everything under the sheetmetal with insecticide and then waited 24 hours before proceeding to make sure I wouldn't wind up in the ER for a Black Widow bite.

1989 Jeep Wrangler Dry
The next day I got around to making the Jeep run. I had a good idea why the clutch pedal went to the floor for the previous owner and sure enough, the clutch master cylinder was bone dry. I topped off the master and then gently pumped the pedal a couple times with the cover off until the bubbles stopped coming to the surface.

1989 Jeep Wrangler Bleeder Screw
The internal hydraulic throw out bearing bleeder screw is on the passenger-side of the tranny. I hooked up a homemade one-man bleeder made from a Coke bottle, some hose, and some brake fluid and then bled the rest of the air to get the clutch working perfectly. With no noticeable fluid dripping from the bellhousing area, chances are the bearing barely weeps. I'll check the fluid level at every other fuel fill up to monitor it.

1989 Jeep Wrangler Battery Plate
The battery that came with the Jeep was not only dead, it was totally corroded. It's an old trick, but submerging corroded battery terminals in a solution of baking soda and water is the best cleaning method. The base pH of the baking soda reacts with the acidic pH of the corrosion and neutralizes it, bubbling off all the nasties.

1989 Jeep Wrangler No Fluid
Popping off the radiator cap revealed no visible fluid. The radiator was nearly empty thanks to a split in what looked like the original upper radiator hose. I topped off the radiator and then yanked the cruddy, dead battery.

1989 Jeep Wrangler Injector
There's a screen around the body of the injector to keep chunks of debris out, which I cleaned with throttle body spray. What little fuel was inside the injector smelled like sweetened varnish, so the fuel in the tank was way skunked. I dumped 5 gallons of fresh fuel in the tank to help it out, used a dental pick to clear some varnished gunk from the injector nozzle, and put it all back together. It would now fire, but the engine ran rough and sputtered.

1989 Jeep Wrangler Cleaned
Finally, I popped off the cap and rotor. The rotor was corroded, so I hit it with Emory cloth to clean it up. The aluminum cap terminals were also corroded so I gave them a redneck polishing with a flathead screwdriver. The low-buck tune up did its job 'cause the engine now purrs like a kitten. At $0.98 a piece for plugs, $16.45 for the fuel, and minus $200 for the Bestop sliders I have a running YJ for $320.37. Next month I'll show you how get the sludge out of the oiling system as well as give the vehicle a proper going over to get it road worthy.

1989 Jeep Wrangler Pump
With the clutch, battery, and coolant squared away I couldn't get the Jeep to fire. Popping off the throttle body air intake cover revealed no fuel was coming out of the injector. I could hear the pump priming when the ignition was turned on, so I popped out the throttle body injector and sprayed cleaner into all the bores to dislodge any gummed up varnish. Priming the pump without the throttle body caused fuel to shoot out the bore, so I knew the pump was good.

1989 Jeep Wrangler Plugs
Moving to the ignition, the plug gaps were 0.060-inch rather than 0.035-inch and the electrodes were pretty carboned up. I had some Autolite plugs in the garage for a small-block Chevy which were close enough to work in the 2.5L.
