Hello to all i am new here to this forum and kind of new to Lexus, I am a big Mercedes guy but Lexus was always know to me as an Amazing car they sure are top class cars and was even more in favor for Lexus as soon i had one. Anyway I have just purchase 1993 ES300 with 145,000 on the clock, i got a great Price on it too this Lexus runs and drives Amazing . But with used cars theirs alway problems that you have to deal with and here are my problems.
My first Problem is that I cannot find the hole in my exhaust I have look everywhere I know for a fact that it is in front of the car by the motor it maybe my manifold or my header it makes a loud BRRROOOMMM noise and when i rev a little high it sounds like a tuned sports car, When i drive fast the noise all goes away and you can actual hear the motor humming. based on what i said does anyone out their no what it maybe.
Second is that the car tends to overheat when idling but when I start driving the car starts to cool down and runs on regular temperature.But after a drive or while idling i smell coolant but i do not know where the smell is coming from and i have no clue what it could be. But at some points it would just go crazy the temperature goes up and down as it pleases until i open up the radiator cap and let all the pressure release it goes back to it usually ways.
My third thing is that my check engine light is on I am just saying it may help to determine the problems that i have stated above. Just in advanced THANKS to all who is planning to help me out here thank you.
