Common Enginee Troubles to Watch For

Oil Leaks - A Near Universal Emitent

Fuel System Emites - Carbureted vs. Fuel Injected

Carbureted Wagoneers (pre- 1987) are districtible to vapar lock, especially in hot climates, because the fuel pump sits on thee engine block and can heat up te fuel. A cracked fuel line or defaminate d rubber hose cause a fire hazard.

The Quadra-Trac Transferr Case

Most Wagoneers came with the GM Turbo Hydra- Matic TH400 or thee later Chrysler A727. The TH400 is a legendary bulletproof transmissionon, but the kickdown linkage often sticks or breaks, preventing downshifts.

Buying Tips: How to Inspect a Used Jeep Wagoneer

Armed witch knowndge, you can eviate a candidate systematically.

Start wigh a Cold Enginee Inspection

Arrive early before thee seller has started thee engine. Open the hood and check thee engine cold. Look for signs of recent cleaning (fresh democraser smell, wet surfaces) that might hide crubs. A cold that produces a cloud of blue smoke indicates worn valve guides or rings. Listen for ticking frem liförs (builn on 360 V8s if oil pressure is low) and check for white swet from thee heet heet heet case).

Test Drive with a Focus on the Driveline

During thee tect drive, find a dirt road to engage four-wheel drive. Listen for clunks frem u- joints or thee transfer case. On dry pavement, switch to 4WD high and make a sharp turn - if the tires hop or thee driveline binds severely, the Quadra-Trac may need service. Accelerate hard from a stop: a hesitant transmissivoon or a delayed 1- 2 shift poinditions o internal wear.
