Hi Guys,
I would like to seek help to locate the bleed valves on my Lexus RX300 year 2002 1MZ-FE engine. After my recent visit to the workshop to have my coolant changed, there is noise in the coolant system. I have tried to park my car at an angle, putting a fully filled funnel on the radiator opening, left the engine running for 3 thermostat opening cycles, keep filling water, switch off the engine let it cold completely, and cap it back. The air bubble did come up but still could not completely eliminate those noises.
One last thing I could try is opening up bleeder valves to let air escape as I couldn't find those screws. I have checked the repair manual but I could not find the top bleed valves. I have seen many using these bleeder valves to release air from the coolant system. Is there one on 1MZ-FE? Would someone, please enlighten me?

Thank you in advance.
I don't think it has a bleeder. Did you have the temperature selector for your heating/cooling all the way on hot?
Hi olandy, Thank you so much! I have switched to "MAX HOT" which still doesn't help much to bleed the air. probably I will get to change the thermostat. The video is very useful!
