Gs430Ger

Thats whats also confusing me. All of the noises doesnt really Sound like a Wheel bearing. Maybe the brake caliper is to tight, as the disc isnt touching the heat shield as thought at first.

Hi everyone, im facing a strange problem with my 01 GS430. First i noticed a strange squeaking noise from the front left Wheel when driving slow (approx. Until 10mph after that its gone) had that noise a few weeks after i bought the car. Already did the front brakes completly + ball joints (previous owner didnt replaced them). After i replaced the brakes, a crunching noise additional occured but only if i drive the car for a few km‘s. The brake disc isnt touching anything (what i first thought), thats the point that is driving me nuts as i now its coming from the left wheel bit not the disc as i thought. I dont now if its the wheel bearing maybe? hope you guys can help me, i have attached two videos where you can hear both noises. IMG_5757.mov IMG_5757.mov IMG_5781.mov

Yeah is still think there is a big chunk of air in the system, because when im pressing rubbertube from the engine to the radiator (when cold), the level itself is expand (goes from below a few cm’s below empty to in between empty/full). But the test is a dead giveaway for me that the gasket will fail at some time. Forgot, that i made a video of the car running to temp. before i did the test. From my perspective that does not even look like alot of steam/smoke (was even less when it got a bit of engine temp). Got a clk320 that is steaming more and doesnt even burn one drop of coolant.

My Co tester came in today and i dont really, what i do with the result. I have put the plug on the reservoir tank (didnt fit that well). Let the car warm up for approx. 12 minutes with a few very tiny revs and at like minute 16 (with around 4minutes of constant reving right around 2k rpm) it turned greenish (Posted a video of the last few seconds of my recording, had to zoom in really far, hence the bad quality). I am not sure how to proceed now. I will try it tomorrow on another car i have, just to be sure, as i still not have any exhaust gas smell in the reservior tank nor at the exhaust pipe. No signs at the oil cap or dip stick too. Just that damn pressure in the reservior. Ordered a Thermostat today and will try to change it + burping the coolant System as a last try. The temperature stayed complety steady the whole time, but i dont think it could start to overheat in this short time? IMG_4691.MOV

I will order a thermostat and some coolant in the next few days, as i also not getting any heat, when the car warms up to operating temp at stand still, only if im starting to drive it. Still have the hope, that its a broken thermostat + air in the cooling system. But my CO2 test should arrive tomorrow and i will check. Had the car on a lift yesterday, found no coolant marks on the block itself, only some oil from the valve cover gasket.

I also thought about the head gasket. Ordered a CO test, that should arrive on Friday. Will keep you updated ps: The car is also not geting warm inside it at idle, even if im putting it on the highest temp.

Hey guys, just bought a 2000 Gs430 and noticed a coolant leak coming from the overflow tube (and also a bit from the reservior cap itself). Topped ist off a bit today (around 200-300ml) and as i put the cap back on, i noticed coolant pushing out of the reservior tube (right below the reservior cap) Added a picture of my engine bay, as i noticed, that there are different versions of the radiator and reservior on the 3uz-fe. As i dont have the radiator cap, as most US spec 3uzs, could the problem occur due to much pressure in the cooling system? The timing belt and waterpump was replaced 20k kilometers ago, the radiator is approx. 15k Km old (OEM Toyota/Lexus one).
