  1. Hi Randall: I replaced the top pulley for the serpentine belt not for the timing belt. Nothing else was done. I replaced the timing belt, water pump, etc. summer of 2013. It doesn't make sense to me either. There was no previous squelching of the serpentine belt other than the morning that it broke. The bearings in the pulley had melted. All I can say is the hesitation is gone. There is way more power and mpg is up. The only think I can think of is the serpentine belt pulley started to fail a while back and some how affected the performance of the engine. The improvement in the performance of the engine was immediate and very obvious. Best it has ever run. So may the lexus gurus can figure out why.
  2. I have a 95 ls400 with serious miles on it. i keep it well maintained but in the last several months i was getting a chronic hesitation from the engine which seems to be a problem with many sc and ls owners. performance has been quite lousy for the last several years. the cause wasn't the fuel system, electrical, etc. but was caused by the top idler pulley. the bearings in the pulley literally melted this week and caused the belt to break so i replaced the pulley. i think the pulley started to fail many years ago which caused my fuel mileage to become horrible and engine performance to suffer including the hesitation and reduced hp getting to the rear wheels. i was shocked at the results. the performance on the ls400 is unbelievable now. there is an incredible increase in hp, fuel economy and the hesitation has disappeared. the engine increases from 2000 rpm to 5000 rpm in a fraction of a second now. the ls400 is now powerful and very fast. it is the best the engine has run since i bought the car 15 years ago. so if you can't figure out why your ls400 or sc400 sucks and hesitates look at the tension and idler pulleys because the answer may be that simple. if they are old and worn you are putting a big drag on that engine.
  3. it is all fixed. fuse blew...due to cigaretter lighter receptacle shorting out the panel due to nut at back of lighter receptacle coming loose and wiring then getting shorted. thanks everybody for your comments
  4. i have a 95 ls 400 and i lost the clock, outside temp and hvac display. i havent checked the fuses but i dont think that is the problem as there is no fuse for these systems only. Do you guys have any recommendations. Thanks, Mike
  5. will wheels 18 x 8 from a 04 sc430 fit a 95 ls400. thanks
  6. will wheels 18 x 8 from a 04 sc430 fit a 95 ls400. thanks
  7. i have rebuilt my 95 ls400 over the last few months and the suspension is pretty tight now. i want to add a strut tower bar and need to confirm that a strut tower bar for a 93 to 98n twin turbo toyota supra will fit. please confirm this. thanks, mike
  8. it feels good to do one of these repairs. my tb repair is great also. i still have a small oil leak which is coming from the back of the engine. i havent checked to see where. i hope it is not one of the seals where you have to drop the tranny to fix. if i have to drop the tranny how much time should that take by an experienced shop?
  9. I like my ls 400 but i am getting extremely bored with the way it handles/rolls so my summer project will be to install the addco rear sway barand the megan coil overs street lp. has anybody experienced these mods? thanks, Mike
  10. thanks control.. is the addco part # 2027? and does it come fully supplied? ez street or street lp megan coil overs? any thoughts on the stock front sway bar or is changing the bushings sufficient? thanks, mike
  11. car is all fixed...tb is replaced and crank shaft seal is replaced. getting the seal out took a long time and it was difficult tapping the new one in. i tapped on the old seal against the new one. there was no issue with the cam shaft snapping over...according to my mechanic (who torqued the crank bolt to 181) it happens all the time and he has never had smashed valves, etc.. i want to think everybody for their help,,,,in particular landar and billy....thanks
  12. i was aware of the 50 degrees move but the general concensus in this forum was that it did not have to be done for pre-98 engines.
  13. Should i expect any issues due to the left cam shaft (drivers side) flopping over and maybe touching the pistons??? This was caused by the cam springs after i took the belt off.
