Jeep

most common problem: your alternator died at some point and your jeep was running off the battery until the battery died.

test the battery. if it is less than 6 volts i recommend replacing it. most 12 volt batteries cannot drop below a certain voltage without suffering permanent damage.

test the alternator. you can either remove it and check it at an auto parts store or you can start the car (provided you already got a new battery) and use a multimeter to test the battery leads. if it tests over 13 volts while running then the alternator is still good (it should be more like 14+volts) and you need to look for loose or disconnected cables from the battery to the alternator.

No.

The only way to do that and have the sensor function properly is to get the correct sensor.

They are located on the exhaust pipe in front and in back of the catalytic converter. There are 2 in all.

For both your heater and air conditioning not to work means you either broke a belt or the belt is loose. Overheating would also be caused by this, because your water pump is driven by the same belt. Do not drive it until you get it fixed, you'll kill that engine by overheating it.

Yes.

Direct fit, no. Is it done regularly, yes.

Has work been done recently? If so check for pinched wires or wires melted to exhaust If not: Check fuses Your car has an ASD relay, that could be a mess, locate the relay and note if it is preventing the car from operation normal (could be a complicated electrical problem if this is the case) this relay may blow a fuse when you try starting car Is there spark? <-- important info that should be included in your refined question

Depends on what kind of Jeeps they are. There are multiple models of Jeeps.

Five quarts.

The engine is built to require it. The inner specifications are of a tolerance to need that viscosity.

The 4.7L is a V8 engine.

It flows in the bottom hose of the radiator and out the top hose.

Overheating can be caused by anything that decreases the cooling system's ability to absorb, transport, and dissipate heat, such as a low coolant level, loss of coolant (through internal or external leaks), poor heat conductivity inside the engine because of accumulated mineral deposits in the water jackets or radiator, a defective thermostat that doesn't open, poor airflow through the radiator, a slipping fan clutch, an inoperative electric cooling fan, a collapsed lower radiator hose, an eroded or loose water pump impeller or even a defective radiator cap.

The cooling system is a group of related parts that depend on proper function from each of its component parts to keep the engine cool. Service the cooling system and replace any under-performing or suspected weak parts. Any component part of the cooling system that is not fully doing its job will stress the others and your cooling system will overheat. The most important maintenance item is to flush and refill the coolant periodically. Coolant should be replaced every 36,000 miles or every three years. Anti-freeze has a number of additives that are designed to prevent corrosion in the cooling system, but they have a limited life span. The corrosion causes scale that eventually builds up and begins to clog the thin flat tubes in the radiator and heater core, causing the engine to eventually overheat.

Check to see if the catalytic converter heat shield is in place or the converter has been hit and sitting too close to the floor pan.

The power distribution center on an 1989 Jeep Cherokee is on the passenger fender well under the hood just rear of the battery and starter relay. It consists of for identical relays in line, the look like four little one inch square blocks.

Jeep does not use inertia/reset switches.

You must remove the oil pan to access the oil pump. It is simple to replace once you get to it.

mechanism is broken or if it is an electric window try holding switch down in down motion for 30 seconds then tap window up on switch until it gets to the top then hold switch in upwards motion for 30 seconds if this does not work then disconnect the motor then reconnect

if not break window then get glass company to repair it then blame them 4 it

Yes, but only on cranks and conrod 'bigends'. It's still the best answer for relatively low temp/pressure bearings.

it all depends on what year the jeep is.
