hi, just made it on my sc400 not myself but at the dealer. anyway i don´t know exact procedure but i suggest you to change waterpump as well it cost me 66$ only and old one was totally off with 104k miles. I hope someone tells you about this procedure it´s not hard but has to be done properly, last owner of my car screwed one of the pully bolt so tightly that mehanic couldnt get it out without damaging the screwhole. It was unpleasent surprise...hope you will do it ok. tom sc400

I had a similar problem and my car engine also stopped twice, dealer told that sensor THROTTLE POSITION (FOR E.F.I) is bad -200$ I have to replaci it i guess.. tom sc400

how about slippery in rainy days? Is there any drastic difference between stock and wider tire? tom sc400

just noticed that I have kind of warning signs below my data? I can´t see anyone else have it? Does anyone know what it means and why I have it? thanks tom sc400 Club Member Group: Members Posts: 25 Member No.: 1914 Joined: 26-June 03 Warn: (0%)

well i was told that iridium plugs are very fuel sensitive (bad quality of fuel will destroy em).? I dont know maybe it depends on car and other staff also but people I talked told that they change those plugs every year... tom sc400

don´t know about sc430 but sc400 can handle with snow no problem as said good tires and slow accelerating comes with it! In my area is snow on the road at the moment and somtimes it´seven fun! Ofcourse there is lot´s of cars which can do it better in the snow but I personally can´t resist the sc400. just my thought´s... good luck tom

how much for this "first upgrade" ? have you ever calculated the cost for this staff? let me know tom

I got good lesson which i´d like to share with you. After I filled up my fuel tank i parked my sc 400 inclined to the fuel lid and it was very big mistake... Today morning I opened the door and it was nightmare... there was such of gasoline smell I couldn´t survive. As you know gasoline steam is highly explosive, some bad coincients (bad connections etc) and you don´t have the car any more. I think I know the cause of this leaking, fuel tank is behind the back seat and apparently fuel leaked out down to the back seat because tank was fulfill. I hope that smell is gone afrer while and of course I never will do it again. tom

did I say spirit levels? quess i did... but you understood me perfectly well so I got my answer thank you! tom

just wondering how they use those spirit levels top of the head lights? i quess for the timing but how? never seen it in any other car... tom 95sc400

hi, exactly my point...any help would be appriciated! tom

No I´ll not buy it from the factory, is there any reasons why should I do that? tom sc400

sorry it didn´t work out with master key.. core is damaged i quess. I´ll let it check someone who knows smth about locks - some thief will open it:) tom sc400

for 400$ i´ll get brand new changer and probably it is the best way. tom sc400

Thank you guys! I´ll try with master key I have the one. I´ll let you know. tom sc400

actually i dont know because i couldnt open trunk inside since i bought the car...as I understand you guys dont have this lock between fuel lid opener and trunk relase button? mhh?

thank you! but still how I know that belt needs replacing? what happens if timing belt cracks? tom

depends which way you like to ship it? by air? by sea? by air i´ll give you just a clue aroud 4-6$ per/kg now if you count engine weight around 200++up kg depends which components you have on it.. you do the math. btw how much for the engine in japan? new one? rebuilt? used? tom

How can I understand that belt needs to be replaced? Is there some more belts which I have to replace from time to time? what happens if some of them blows up? Accurate inf. is appriciated. tom 95sc400

:))) jeah you dont understand my problem. I´ll try once again to spell it. inside the car, left side below the dash I have fuel lid opener and trunk relase button but between of these two I have lock which is for locking trunk relase button for security I quess... I explane how it should work: if I push this lock down I cant open trunk inside of the car. Now if i´d like to open trunk from inside of the car I have to turn ignition key in this lock and it relocks the trunk opener.. damn it is hard to explane i´ll try to get photo for you tom sc400

I can´t agree with you as mush I experienced and read about lexus it is one of the best cars out there...but it is still made from same steel etc. I quess that previous owners of your lex were bad host... I suggest you to replace it with another one which is well maintained. your fueling problem can be fixed if you clean up sifter inside the fuel hose..I just can´t imagine how to do it... maybe someone knows. good luck! tom sc400

I think the best way is drill the small hole back side of the headlamp as AWJ suggested if i´am correct. tom sc400

I allways use best oil for my sc and suggest you to do the same! tom sc400 What is synthetic oil? All motor oils are made up of base oils and additives. In general, fully synthetic motor oils contain non-conventional, high-performance fluids and a system of additives to help prevent wear, keep an engine clean, flow easily, maintain viscosity, prevent rust and reduce friction. The result is a lubricant that remains liquid and slippery under the widest possible range of temperatures and engine conditions. back to top What makes synthetic oil superior to conventional oil? Historically, conventional oils lack the performance of synthetic oils in the areas of low-temperature performance and high-temperature oxidation stability. Conventional motor oil is made up of an inconsistent mixture of long and short chains of carbon and hydrogen atoms. In the extreme heat of an engine, short-chain molecules can evaporate, and unstable molecules can oxidize and break down. Conventional oils also contain much greater amounts of impurities, such as sulfur, reactive and unstable hydrocarbons, and other undesirable contaminants that cannot be completely removed by conventional refining of crude oil. Mobil 1® with SuperSyn™ uses high-performance fluids, including polyalphaolefins (PAOs), along with a proprietary system of additives. Each Mobil 1 with SuperSyn™ viscosity grade uses a unique combination of synthetic fluids and selected additives in order to tailor the viscosity grade to its specific application. back to top What is the difference between a fully synthetic motor oil and a synthetic blend? All motor oils are made up of base oils and additives. In general, fully synthetic motor oils use non-conventional, high-performance fluids. Semi-synthetic oils (also called "blends") usually use only a small percentage of non-conventional, high-performance fluids in combination with conventional oil. back to top Are there advantages to using synthetic oil in a motorcycle? ExxonMobil® offers three Mobil 1 fully synthetic motor oils for motorcycles. Although Mobil 1 15W-50 has been used in 4-cycle motorcycle engines, ExxonMobil engineers recommend using Mobil 1 Motorcycle Oils, since they have been specifically optimized for motorcycle applications. Be sure to follow your owner's manual for recommended oil and filter change frequencies. back to top How should I dispose of used synthetic motor oil? You should follow the same environmentally sound procedures that you do with conventional motor oil. Here are the U.S. Environmental Protection Agency's (EPA) guidelines for disposal: Do not dump used motor oil in the trash. Do not pour it on the ground or down the sewer or storm drain. Place the used oil in a closed container.Take it to a service station or a collection location that recycles used motor oil. Do not burn used motor oil in a space heater.To make it easier to recycle, do not mix motor oil with other substances such as gasoline or antifreeze. Most Exxon and Mobil service stations will take used motor oil from do-it-yourselfers and will follow EPA-approved recycling. Please note that it is acceptable to mix used Mobil 1 with used conventional motor oil. In short, Mobil 1 with SuperSyn™ should be disposed of in the same manner as used conventional motor oil. back to top Can different synthetic motor oils be mixed together? Mobil 1 with SuperSyn™ is fully compatible with conventional motor oils, semi-synthetic motor oils and other synthetic motor oils, should it be necessary to mix them. But the superior performance of Mobil 1 with SuperSyn™ will be reduced by diluting it. back to top Can I go longer without changing my oil if I use a synthetic? While Mobil 1 has given excellent results in extended oil drain tests, the safest and recommended practice is to follow your owner's manual. You can go all the way to the maximum mileage or time frame shown in your owner's manual for oil changes when using Mobil 1 with SuperSyn™. This allows the reserve protection capabilities of Mobil 1 with SuperSyn™ to cover the unusual or unexpected driving conditions that we all experience from time to time. Oil change intervals can be as short as 3,000 miles or as long as 15,000 miles on some new cars. Mobil 1 with SuperSyn™'s high-performance reserves give you the confidence to go the full mileage or time frame recommended by the vehicle manufacturer. Mobil 1 with SuperSyn™ is especially suitable for the latest vehicles with extended drain intervals or vehicles with oil monitoring systems that vary oil drain intervals.

It is metal one and really tiny:) tom

AWJ is this antenna you are talkig about in the back side of the roof - this small one 5cm high? I allways wondered what for is it... tom sc400
