1992 Lexus Ls 400 - Page 6 - Answered Questions & Fixed issues

their a broken cabe from the batteyr terminal

castrol 10w 40w just like all toyota made cars

Issue in your cullum Stearing Ignition Swich or Short in your Alternator Regulator ....unplug your alternator and try if your fuse blow again ....

The electrical ignition switch has probably shorted out. It will be mounted on the trans next to the shidt cable

You have a light bulb out. Have someone assist you in checking the lights as you turn them on. Parking, running, tail, head, reverse, and brake lights all need to be checked.

The switch is fine if the third brake light is functioning. Even though the tail lights work, the filament for the brake light can be burned out. Sometimes they look intact but are still burned out. Replece the bulbs.

How to set the timing on a Lexus LS400 when changing the timing belt

hi, this must be a dead short. if you connect a lamp and lamp holder with the battery and the other side of the fuse if the lamp is lit the short is still present.

Some things to look for if your car is overheating: THermostat stuck in the closed position, cracked head, blown head gasket, leak in radiator, punctured hose, low coolant, cracked block.

Examine the cooling system for obvious leaks in any hoses or parts of the radiator. Let the car run until hot and check the upper and lower hoses. They should both be hot and firm to the touch when the thermostat opens. If the top one is hot and the bottom one is cool and flexible then coolant isn't flowing through the system which most likely is a stuck thermostat. If the coolant level is low you have a leak spomewhere in the system. Have someone pressure test the system if you can't do it yourself. Good luck!

If the radiator fans are not running and the circuit breakers are ok, then this can affect the efficiency of the a/c system greatly.

The ambient air flow that is created when the car is moving shows that the a/c system is working except for the fan.

Check that any fuses and 'fusible links' are not broken or tripped. 'fusible links' can often be the cause of a fan not working in a car. They are multicolored and have a barrel of foam around them to identify them coming off of the starter, in some cars.

If you have trouble tracing the power in the circuit, it may be necessary to take the vehicle into a repair shop that deals with electrical anomalies such as these.

An electrical shop for automobiles, or an a/c shop or the dealer can often find the root of the problem rather quickly, using a test light, and some knowledge of the Lexus schematic.

Check for rust and check the pressure in the engine - if when you remove the oil fill cap the gases are bursting out then the engine is worn out. Check the transmission's oil  and ask him if the filter has been changed - without that the life of the gearbox has been reduced.

by removeing battery cable ck ths spark if it sparks sucnificly ck for shorts in electical system a little spark is ok could be radio and clock

REMOVE THE REAR SEAT ,THERE IS A OPENING IN THE BODY TO REMOVE FUEL PUMP WITHOUT DROPPING THE FUEL TANK..

VERY EASY REPAIR

thats kinda difficult to guess due to the engine safety secury cuts it and the relay also will cut it, if you have no security light on at all then i will start by checking the relay located in the fuse block, swap it with some other one to test it.

This job requires special tools and special training. If you lack either, you risk SERIOUS personal injury. Injury comes VERY EASILY!

You need to address oil levels, proper and legal refrigerant recovery, system evacuation, and recharge.

You were planning to also replace the receiver/dryer, correct? It also needs the oil in it measured and incorporated into the amount of oil (in %) that would need to be added. FAILURE to address these and other issues will guarantee premature system failure and likely compressor damage.

Take this job to a qualified shop.

Sorry

Man! Lexus is ****! I have the same problem.
