SOURCE: Replacing water pump in 98 Lex GS300

Removal of the crankshaft front pulley/damper can be removed without any damage being caused to the cam belt.
They are a good fit on the shaft, I personaly use a lead tup, weighs 2lbs and will not damage anything if used properly.
Tap equaly all the way round the pulley, that should be ok.

SOURCE: timing belt replacement 1997 lexus lx 450: when?

well don , if this is a 4wd , actually even if it wasn't i show it to have locking diff(s) , if you have 4wd i show you to have a switch and a light somewhere on dash display indicating if it is locked in or not . , if you look at the passenger side of the rear differential you might see some electronical gizmo attached to it . i recently worked on a lx470 , it was awesome , i cracked the woodgrain cover around the power window switch , ouch , it cost $500 just for that little piece of woodgrain , lexus is very proud of their parts , lol , enjoy that vehicle . i would sure appreciate a FIX YA vote . thank you .

SOURCE: 98 lexus gs300 codes p1120 p1121

I wanted to start a thread specifically about failures within the throttle body concerning the GS300 (1998 in my case)

My symptons were:
VSC, VSC OFF, and ENGINE Lights would come on, followed by my car going into Limp Mode, where only that last 25% (if that) of the throttle would respond (basically have to floor the pedal to even move at all).

During the mornings, or when the engine was COLD, the throttle operated normal...then once the car warmed up, usually at about 10 mins, the problem would start...it happened intermitantly at first...1 or 2 days over the course of a week, then it became more consitent, until last week it became a daily problem.

The first part I tried was the Throttle Position sensor, which is on the front side of the throttle body, and the easiest thing to replace...this didnt help at all. $300 part from Lexus, $80 part from RockAuto.com (exacly same part toyota OEM)

THE PART THAT FIXED THE PROBLEM:
===========================================
"Idle Valve Motor", which is the larger electrical object next to the TPS on my 98 GS300. Problem is solved.

The Codes I got were P1120 and P1121 - Accelerator Sensor problem. However it wasnt really the Accelerator Sensor, it was indeed to actual electrical Motor that controls the opening of the Butterfly valve inside the Throttle body.

I found the problem by good old trouble shooting, and using an ohm meter to see if the throttle electric motor was getting elev, I found that the elec motor just to the left of the TPS was basically freaking out and shutting down. The Accelerator Pedal Sensor is on the Back-side of the throttle body where the throttle cable connects to, and has a spring on it. It was fine.

GS300's are indeed "drive by wire" concerning the throttle...the cable triggers the Accel Pedal Sensor, which sends a signal to the ECU, the ECU then sends power to the Idel Valve Elec Motor (next to the TPS), which opens and closes the mechanical butterfly valve, then the TPS sensor detects how far the elec motor is actually opening the butterfly valve...its a closed-loop feed-back system, meaning any failure in any sensor will cause the entire systm to fail.

The throttle cable apparently is ONLY there to allow the fail-safe of having that last 10-25% throttle when the electronic system fails...there is a gearbox inside the throtle body which allows the tail end of the throttle to manually engage the butterfly valve...the rest of the time, the butterfly valve is 100% opened and closed via the idle control motor.

Timing belt should water pump be changed as well?


If it's a ES300 yes replace water pump, due to timing belt drives water pump, if it's a GS300 no need to replace water pump, not driven by timing belt.

I am changing the serpentine belt on my 1994 Lexus Gs300 and cannot find the tensioner bolt to apply tension to put the belt back on. Where is it located?


the tensioner is generally spring loaded. check that you have the belt correctly routed. then you may need to attach a socket/rachet to the center bolt of the tensioner to move it enough to slip the belt on. if it moves freely it likely needs to be replaced as well.

My 1994 Lexus GS300 (220,000 miles) Just stop, while driving.


It really sounds to me like you need a new alternator, but you should have the battery fully charged and checked as well. Before anyone puts an alternator in, make sure they check the belt condition and tension, this is often overlooked and may be the reason you're buying alternators all the time

Replacing water pump in 98 Lex GS300


Hi,

I bought this old car and the seller did not provide a manual book with it, I got the luggage compartment not working over a sudden after i bought the car, also the keys are not turning, so i can't open the luggage at all. I tried to look for the fuse box maybe i could find the fuse burnt but i can't find the wright location or the fuse.
I need a diagram for the fuse box if it's inside the car not at the back, and if it's on the back how can i open the lauggage then?
