Did you torque the head bolts in the proper pattern? Sounds like your head gasket is leaking.

Sounds like you need to reset your alarm kill switch, which should be located near the driverside kick panels. GL.

First check your ground wire. Second check your main fuse. GL

The bolts are "Lefty Loosey"

It sounds like your previous thermostat was stuck partially open ( that's why the engine temp never reached mid point on your temp gauge) . Why you are smelling the rubber is another issue. I suspect some antifreeze from the thermostat change got onto your car's serpentine belt and is causing it to slip some...until it wears off or you clean it off the belt it will stink.

assuming you have the right rated fuse in their you might want to check for short-circuit after diffuse i.e. chafed wire

if the vehicle was not designed for hids its best to make a relay system off the original head light wiring, like you would do for fog/spotlights this would draw power direct from the battery and not the original wiring as the original wiring may not be able to take the drain from the startup of the hids. there are kits for vehicles so no wire cutting is involved, just plugs into the original wiring. same with led kits. https://www.hidextra.com/lexus-es300-hid-kits/

Sounds like a bad ground or bulb that's not put in right can be the front or rear bulb sockets or just a bad bulb.

In order to change the back light bulbs you must remove the cluster from the dash.

Your wheels each have rotor speed sensors... 2006 LEXUS GX470 4 7L V8 ABS Wheel Speed Sensor RockAuto These are easily bent or misaligned... and can be put into a position of INTERFERENCE with the (particularly ... in YOUR case "RIGHT FRONT") ROTOR... These parts ARE NOT CHEAP... and WILL ADVERSELY impact the operation of BOTH TRACTION CONTROL & ABS (anti-lock brakes)... It is a WORK ERROR... while your BRAKES were being "inspected" ... your rookie dealer "mechanic" most likely did something... ROAD-HAZARDS "can" break these parts... but reasoning with your fully functioning brain... (OCCAM'S Razor) Occam razor Wikipedia the free encyclopedia You should NEVER HAVE LEFT... without having a SERVICE PERSON making a note of your ABS & TRC lights... You do have rights... and government licensing boards... In the unlikely event your "dealer" FAILS to recognize their obvious WORK ERROR... OCCAMS razor: When you hear the thunder of hoof beats... Think HORSES... (not Zebras) https://en.wikipedia.org/wiki/Zebra_(medicine) I have had many BAD experiences with DEALERS... (& I trust my lying eyes)... I'm just saying (in my opinion)... Get back to that "DEALER"... pronto...!! Carnac the Magnificent

I had a 94 sunbird and when we stopped, it would start running a little rough and the speedometer on the dash would start raising up sometime to 20 mph, and the car was not moving. I finally took it to a shop and they said it was the voltage regulator which was built into the alternator. They changed the alternator and we never had the problem again. The speedometer on the car was controlled by and electric circuit not a cable. You should have the code checked it can help diagnose the problem. Most auto part places where I live will tell you the trouble code for free with their code reader.

The 2003 Lexus ES300 has the most common hook-end wiper arms. If you purchase the replacement blades first, there will be additional instructions/illustrations on the replacement packages. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.
