Always ran warm or hot.
Replaced water pump at 90,000 miles and again at 165,000 (may not have needed it though).
Due to what was poor performance I replaced a fuel injector - turned out it was the catalytic converter.
Front window power steering wires kept coming loose from repeated door shutting.
Replaced power brake booster and master cylinder at 170,000 miles.
Power steering high pressure hose leaked - never did fix it, though.
Rear door hydraulics went at about 170,000 - never replaced them, though.
Lights in the radio went out and never could see what station I had on.
Replaced starter at about 150,000 miles and alternator at about 180,000 miles.
Best vehicles I've ever owned. I put 115,000 miles on it and many were stop and go miles while I delivered pizzas for 2 years in snow country. Four wheel drive was a real blessing.
I took this vehicle to places I should probably never been by myself, but it was very, very reliable.
I liked it to the extent that I had to got another 1989 in better shape (but with 227,000 miles) and did some replacing of some items and have just donated the old one to a charity organization. LOVE MY JEEP!
