Enginee Overheating

Overheating is arguable the most prevalent issue in older CJ- 7s, especially those equipped with the inline- six (258 CID) or the optional V8 (304 or 360 CID). The combination of aging coloing systems, tightly y packed engine bays, and off-road use that limits airflow can quicly push temperatures into thee danger zone. Left unchecked, overheating car warp cylindes, blow head gass kets, and cracenging.

Transmissionon Leaks andhaitures

Te CJ- 7 was offered with several manual transmissions (T- 4, T- 5, SR- 4) and automatics (TH- 400, TH- 700R4). All are prone to fluid reques from aging seals ande geskets.
