    es300
  1. Hello. I also have a 98 ES300. There is an automatic transaxle differential that is to be filled separate from the automatic transaxle. The diagram I have shows the drain plug facing the ground (as it should). The bolt you have to unscrew (and use a syringe or gear oil pump to add ATF) is several inches up to the side facing the driver's side door. After draining, you add the ATF until it just starts to seep out of that fill hole- then tighten the plug. The recommendation is that this differential lubricant is changed every 15K, whereas the automatic transaxle lubricant (both ATF) is changed every 30K.
  2. Check your sway bar (stabilizer bar links). They are small connecting rod links on the front right and left sides. I had a rattle on my 1998 es300 on both sides and these links were both broken. Probably broken from hitting a pot hole or two while driving. Take off your wheel, look for this part on the right side. It's about a foot long with ball joint ends that bolt to your suspension. Grab it and see if either end is loose or appears broken (usually at the ball joint). It's about a $30 part- it may save you some money if this is it.
  3. Anyone know where the rear engine block coolant drain is? I am replacing a fuel injector and need to take off the upper intake plenum. I can't do it until I find this drain. I found the ones for the front block and the radiator- just cant seem to find this one. Thanks for any help you can give!!
  4. I didn't do enough homework on mine... I did buy a new coil after testing the one for cylinder 1 on cylinder 3. The code jumped- I purchased and replaced the coil and still getting a p0301 code -cylinder 1 misfire. After this, I checked for the clicking noise that is supposed to indicate a working fuel injector. All three of the fuel injectors in the front bank seem to be firing(clicking) faster than the one in cylinder 1 in the back. I couldn't get my screwdriver next to the other back two for comparison- but I wouldn't think they would run at a different rate than the front ones. Anyone had a similar problem or have any advice for me? Check the computer signal to the coil if not signal founded unto the plug verify the cable maybe one them loses the cable isolation and perform a false signal to the computer. Thanks for your reply greenv! By cable isolation, are you referring to the spark plug cables/wires? or the wires going to my fuel injectors? This is all quite new to me. . thanks for your help!
  5. Anyone out there ever replace a fuel injector on their 98 or similar es300? How difficult is it?
  6. Did you ever find out the problem with your misfire in cylinder six?

  8. Thank you!! I was reading your comments about your misfire and I have the same problem- I think. I switched coils from the 4/1 cylinders to the 6/3 cylinders and the code moved from cylinder 1 to cylinder 3. I think that is probably a good indication that it is the coil. Thanks for your help. Should I buy a part directly from the dealer for my 98 es300 or an auto parts store? I appreciate any feedback you can give.
