1988 Jeep Cherokee Additional Info:

We have for sale an 88 Cherokee pioneer. This Jeep has had a ton of new parts replaced in the last three years. Most all steering/power steering components are new, front axle components replaced, u joints, all engine accessories replaced, clutch and throw out bearing master cylinder replaced, rear freeze plug replaced, pretty much all coolant system was done minus the Overflow reservoir, new Upgraded for port Injectors, holds oil well burns oil a bit which was typical of these motors. New windshield, radio, and spare tire, tires are okay not dry. So what is wrong with? The motor has piston slap when it was over hauled before we owned it piston six rocks bit it doesn’t hurt the motor it’s been running over 120k like this. The oil, coolant, and head are good. Last parked 1-2 years ago when she overheated, we been starting it and it overheats quick we believe the coolant system has a clog, we bought newer cars since and have no use for this one haven’t bothered looking into it since it was parked. Lastly all the important gages work however some of misc. ones do not.
