Sure, but theres not a lot of room back there to put them, several places make enclosures for the wrangler, I'd start with Crutchfield or Quadratek.
The Jeep Wrangler has four seats, as does the Jeep Wrangler Unlimited. There are, however, companies that manufacture a portable third row seat for use in the Jeep Wranglers to add extra space.
Through the plug on the middle rear of the case.
If you have to ask then take it to someone who knows how to work on A/C. Injury or death could be caused if you get on the high pressure side and it is not worth the risk.
There are several different ways to add and change seating in the Jeep Wrangler and the Unlimited and the seats can go into the other vehicles. You can use the back seat of the Wrangler to go in a third row of a Wrangler Unlimited though the mounting brackets sold aftermarket from a company that are not NHSTA tested. There is a business called Little Passenger Seats that makes seats for the Jeep Wrangler Unlimited that will also work for the Wrangler and they have safety tested their product and passes NHSTA regs. The problem with adding and switching these seats on your own are finding and mounting seat belts. That is why Little Passenger Seats is great because the brackets are included and seatbelts come mounted on the seat. Check it out.
A 1993 Wrangler would not have any sort of anti theft system from the factory. So any system on the vehicle could be easily removed by unplugging, or unhooking any add on wires.
Just unscrew the cap and pour it in, it is on the drivers side engine compartment, high up on the firewall.
JC Whitney and Quadratec both sell kits to add aftermarket airconditioners with factory specs.
Most of the 2000 Jeep transmissions hold 6 quarts. Start with about 4.5 and add until the dipstick shows a full system.
Because its a Jeep. You're driving a tent on wheels with the aerodynamics of a brick. Plus add in over sized tires and bad driving habits, you will get even worse gas mileage.
You add the fluid down the dipstick tube.
I think 32's will be too big without a lift, you can add a cheap shackle extension lift and fit them in.
You need to check your oil, sounds like you are dangerously low!! Be sure to check it to see how low you are and then add the needed amount...
