If your Lexus RX 300 cigarette lighter will not remain in place when pushed inward, there are a few steps you can take to repair the problem. You can fix a cigarette lighter for a Lexus RX 300 as a do-it-yourself project, but if your efforts do not solve the problem, you should take it to your local Lexus dealership for repair service.

Instructions

1

Retrieve your manual. Then, check the fuse box. The fuse box of a 2001 Lexus RX300 is located behind the coin holder drawer, to the left of the steering column. Check your manual to see which fuses operate the cigarette lighter socket. If the fuse is blown, you will see a small, broken wire in the interior of the plastic shell of the fuse. Replace a blown fuse with a fuse rated for the same amperage.

2

Pull out the ash tray to gain access to the lighters wiring connector. The 12 volt and ground wires are connected to the socket. Also, identify an L-shaped wire that has a rubber coating. This is a fuse. Find the two small terminals at the bottom of the L-shaped, rubber-coated fuse. Remove the fuse, then bend a paper clip in an L-shape and place it where the L-shaped, rubber coated fuse was positioned. You should position the L-shaped paper clip at the end of the socket.

3

Remove the ash tray from its panel. Remove any small Phillips screws. Then, remove each spring found on the side of the ash tray.

4

Disassemble the lighter assembly or lighter housing, by loosening a hex nut at the bottom of the lighter assembly. To accomplish this task, the panel must be off. Then, reassemble the lighter assembly. Check to see if your lighter will stay in position when pushed inward.

5

Replace the lighter with a standard size cigarette lighter from your local auto parts store. If a fuse is not burned out, and if disassembling and reassembling the lighter socket still does not help the lighter stay in, take your RX 300 to a Lexus dealership.

6

Explain the problem with the RX300 cigarette lighter fixture, and ask a Lexus service professional to inspect your cigarette lighter socket. The dealership should inspect your RX300 to check for any possible wiring or electrical problems.

The Nissan 300ZX is a sports car manufactured by Nissan from 1984 to 1996 in the United States. The 1984 Nissan 300ZX has a 6-cylinder 3.0-liter engine, and some models have turbocharged engines. All versions of this vehicle use fuel injection, which requires a highly-pressurized fuel system. The fuel pump in the 1984 Nissan 300ZX is within the fuel tank, so you must remove it to install the fuel pump.

Instructions

1

Start the engine and disconnect the fuel pump relay in the fuse box. Wait for the engine to stall, and attempt to start the engine three more times to ensure you have completely relieved the pressure in the fuel system. Turn the ignition switch off.

2

Disconnect the electrical connectors for the fuel gauge and fuel pump in the trunk. Place a hose into the fuel tanks filler tube, and siphon as much fuel as possible into a gasoline container.

3

Detach the ring for the fuel filler neck on the fuel tank with a socket wrench, and remove the right rear wheel. Disconnect the protectors for the fuel filler tube protectors and the fuel lines to the fuel tank.

4

Support the fuel tank with jack stands, and loosen the bolts for the retaining straps on the fuel tank. Disconnect the fuel tank and remove it from the vehicle.

5

Turn the retaining ring for the fuel pump counterclockwise with a hammer and brass drift. Remove the retaining ring, and lift the fuel pump out of the fuel tank.

6

Install the new fuel pump by performing steps two through five in reverse order. Replace the relay connector in the fuse box, and fill the fuel tank. Start the engine, and check for fuel leaks.

The 1968 Ford 300 was a six-cylinder engine equipped with a single-barrel carburetor. The engine was first produced in 1965 and was largely based on the slightly smaller 240 engine. The engine is considered by some to be one of Fords most reliable six-cylinders of the era and was known more for its torque than its horsepower. Due to the engines simple design, rebuilding the 300 is fairly straightforward, provided that the engines specifications are followed closely.

General Specifications

The 300 featured a stroke of 3.98 inches and a bore of 4 inches. The compression ratio was 9:2. The 300 produced 170 horsepower at 3,800 revolutions per minute and 283 ft.-lbs. of torque at 1,600 RPM. Normal oil pressure is between 35 and 60 pounds, depending on the speed of the engine.

Tune-up Specifications

The 300 was equipped with Autolite brand BF-32 spark plugs. Spark plug gap is .034 inches. The distributor point gap is .027 inches. The distributors dwell angle is between 35 to 40 degrees. Ignition timing is 6 degrees before top-dead-center. Hot idle speed is 600 revolutions per minute with the headlights and the air conditioning turned on if the engine is mounted to a manual transmission. Hot idle speed is 500 RPM with the headlights turned on and the air conditioning turned off if the engine is mounted to an automatic transmission. Cylinder compression must be between 155 and 195 pounds. Fuel pump pressure is between 4 and 6 pounds.

Valve Specifications

Valve spring pressure for the 300 is 80 pounds at 1.66 inches. Stem clearance for both the intake and exhaust valves is between .001 and .0027 inches. Stem diameter for both the intake and exhaust valves is between .3416 and .3423 inches. The valve seat angle is 45 degrees, and the valve face angle is 44 degrees. Valve spring installed height is 1-1/16 inches.

Pistons, Pins, Rings, Crankshaft and Bearings

The 300s piston clearance is between .0014 and .0022 inches. Compression ring end gap is .010 inches. Oil ring end gap is .015 inches. Wrist pin diameter is .9121 inches. The rod bearing shaft diameter is between 2.1228 and 2.1236 inches. Rod bearing clearance is between .0008 and .0015 inches. Main bearing shaft diameter is between 2.3982 and 2.3990 inches. Main bearing clearance is between .005 and .0015 inches. Crankshaft endplay is between .004 and .008 inches.

Cooling System Specifications

If the 300 was equipped without a heater, the engine holds 12 quarts of antifreeze. If the engine was equipped with a heater, the engine stores 13 quarts. If the engine is equipped with or without air conditioning, the radiator cap relief pressure is between 12 and 15 pounds. The thermostat opens at a temperature of 195 degrees.
