Hello, there I have a 1992 Es300 had the same exact problem replaced the most suspicious culprits that would be behind overheating (water pump, power steering hose, radiator, thermostat, even ran the little blue gels through the radiator system to find a leak nothing still over heating and coolant over boliing). One simple thing you oughta check is the controll fan unit located behind the glove compartment. This little gadget could be the root problem of your woes. The CFU has little diodes ( small battery looking thingy's) if you look carefully at the top of one of those diodes and it has a bulge it is blown. So you will have to replace the whole unit. It doesn't cost that much the only issue is the labor involved in getting to the control unit it is a pain. The CFU controls the Fan's speed mainly telling the fan when to kick in on high gear to cool the engine and prevent over heating. I worked long and hard on this believe me one simple thing. Later on when taking a trip I blew a head gasket and instead of doing the heads I replaced the whole block with a used one that was checked for compression and all and was guranteed on the mileage. Replacing the block was much cheaper than getting the heads done since the engine was already knocking. I hope this helps.

Hello all, Has anyone experienced this problem. When I rev the engine at a standstill I can hear water gurgling in the engine comaprtmenet or whenever I take off I can hear water sort of shift like its has settled somewhere in the engine. Does anyone know what could be causing this ? an answer would be much appreciated.

I have a 92' lexus Es300 and had the same problem. At first we found out the hose leading from the power steering to the fan was leaking so we replaced that to keep the prerssure as its suppossed to be. I drove for a day the overheating and coolant boiling flared back up. Long story short we found out why... It was something as simple as a the cooling Fan ECU. One of those battery looking electrodes had blown making the fan not kick in to cool the car when its suppossed to. Chk on that it may save some dough. The only thing is that its embedded deep in to the dash by glove compartment you and that may be the bulk of your labor.

Hi all, Happy Newyear to all!. Can someone tell me how to change the license plate lights in a 92Es300?.

Hi Martin, I had the same problem about a month ago. I was driving down to TX and the car just lost power, stalled and died. turns out I blew a Head gasket. I had it towed back to Ks to my mechanic and he explained it was useless to just repair the Head gasket since the engine was already knocking. So He suggested getting a rebuilt or reused engine which I agreed to and got it swapped with an engine with lesser "guaranteed miles". The whole job cost me $2000 since I also got a new radiator installed too and other peripherals. Men you can't believe like you said what this shops especially in TX are asking for in term of price. But luckly I had a good mechanic back home it runs like a top.

Hi all I have a 92' lexus Es300 with 180,000 miles. About 3 weeks ago while taking a trip to Dallas it died in the middle of the highway. Long story short I blew a head gasket which in turn ripped the radiator hose to pieces. My local mechanic says it usesless to fix the head gaskets as the engine knocks. So he suggests getting a newer motor with lesser miles on it either from salvage yard with guaranteed miles. Has anyone experienced this kind of problem if so what did you do?. I love this car I'd rather repair it than byuy a newer model.

hi all I have a question on a power window regulator on a 92 lexus es300. my power window regulator won't bring the passenger window up but will bring will roll it down. As a result the passenger window is all the way down and I can't get it to come up. my question is could the power window regulator/motor gone out even though it rolled the window down . If so how do I manually bring the window up temporarily.

hi 91lexus I would venture to say on the metallic barb when accelarating and letting go of the gas pedal at slow speeds it is probably your mounts. I say this after having the same problem atleast on the metallic barbing part. check your front mounts, then your rear usually the rear is the culprit, then then dogbone strut. I am not disagreeing with sk's answer but after replacing the mounts on my 92'es 300 it run like new. For a car as old as yours and mine motor mounts do tend to wear out at that age.

I was wondering if anyone has this problem. when ever I step on the brakes on somedays a whining noise can be heard coming from the instrument cluster panel direction. Does anyone have a clue what this might be?. Also when the car is in motion and later giving or stepping on the gas pedal and/when releasing the engine rocks to and fro. I replaced the dogbone mount strut and the front motor mount just recently . Could it be the rear motor mount? its really dicerning because there is always a backlash feel when giving gas and then letting go. I always thought it should be a smooth transition with no feel if any when giving and releasing the gas pedal.

hi interested in a rear motor mount and the cigarette lighter console.

Hi guys my cruise control actuator assembly nut broke off while I was trying to tighten it. I was wondering if I could replace just the nut or would I have to buy a whole new cruise control actuator device?. Also while it broke of I realized the car was stuttering when I drove it. The idle is very rough to a point where its vibrating some engine parts. It runs and sounds as if its on one spark plug and but I know thats not the cause. Any suggestions as to what the stuttering and rough idle could be?. I was trying to adjust the throttle cable and so I assumed that was the place to start since the car has a back lash when I step on the gas and when I release the gas pedal any suggestions on that engine jerk problem?. I replaced the front and dogbone engine mounts could it be the rear motor mount causing the engine to jerk back and forth when pressing on the gas pedal and on letting go ?. it should be a smooth transition when giving gas and on easing of the oedal too Please help thanks. Also I thought the stuttering and rough idle could have been a result of too much fuel in the system since I was occassionaly tugging on the throttle cable could this be it?. I appreciate your feedback guys.

Thanks all for your input. Where are the EGR valve, throttle return springs located in a 92' es300?. I would prefer to work on it myself rather than have some one do it thats if it's not too involving. Also I tried to clean my air intake sensor but all I found when I took apart was a chamber that you could clean with a swifer duster. where is the air sensor located and how do I get to it to clean it?. In regards to the Engine jerking Toysrme suggested a worn out dogbone mount I already replaced it with a new one. I would like to know more about adjusting the throttle cable and return springs thanks all.

Hi all I have had my 1992 ES300 in good mechanical and suprisingly body condition I have had it for about a year and a half now with little or no problems . This car has 167000 miles on it I have traveled the country with it to miami, dallas, kc you name it .I have one problem though every time or most of the time when stepping on the gas pedal and letting go . The engine kinda jerks like something is loose or something it should be a smooth transition when giving the pedal some gas and then letting go there is always a gunk noise or feel . I just recently changed the front motor , and torque strut mounts but it still does it. Also when cruising at a speed of 40mph with the foot on the pedal the car starts to jerk in small heaves. Its not a major deal but I sure would love to have it running almost like new. please help thanks!!.
