On a 2000 camry xle v6. Someone told me there is cable that is connected to the thermstat chasis as a ground. Is this correct?

There are two grounds in that area one going to a bracket bolted to the valve cover and one going to the transmission. This is on the ES/Avalon 1MZ which for some reason I end up working on not the Camry 1MZ so maybe the non-VVTi engine is a bit different. If anyone will know it's insightbrewery. The 'stat is a bit hard to get to compared to most Toyota's I work on.

I don’t remember a ground on mine either. I did my 2000 1mz-fe but that was a year ago.

You're all correct, I just double-checked both my '99 Camry V6 (non-VVT) and my '01 ES300 (VVT): there is a bracket that bolts to the LH head that the small ground attaches to, and the larger ground goes to one of the starter bolts.

'01 ES300:




...and '99 Camry (note the ring terminal-shaped witness mark on the bracket where the ground attached before):

Thanks for the pic. Its not on the housing but on the bracket.

Look how this guy explained it to me. Not clear at all
.
The ground wire I am referring to (on a V6) runs from the thermostat housing,

The ground wire I am referring to (on a V6) runs from the thermostat housing, where it bolts on. Follow it from there in the direction of the strut tower. (It pretty much follows the path of the engine torque strut mount) My wire has a quick disconnect just about in the center of its approximate 12 inch length. (I assume it's factory) The "corrosion bubble" I found is hidden from view as it formed under the wires black insulation covering. It formed in the section closest to the thermostat housing.
Are you talking about the passenger side water neck, where the "radiator" cap is? I took a look at the service manual for ground points it's surprisingly poor a few grounds I know the car has are not shown.

Same, I got two diagrams, one for engine room and the other for body; have triangles pointing out where grounds are and they miss the straps.

My instinct with a part number to work with is to dig up the parts diagram www.japan-parts.eu

This is what the guy wrote to me. I did not write it. He told me this will solve my lights flickering. I was just asking here if anyone has seen this ground wire he is talking about.

Here is what he wrote. "The ground wire I am referring to (on a V6) runs from the thermostat housing, where it bolts on. Follow it from there in the direction of the strut tower. (It pretty much follows the path of the engine torque strut mount) My wire has a quick disconnect just about in the center of its approximate 12 inch length. (I assume it's factory) The "corrosion bubble" I found is hidden from view as it formed under the wires black insulation covering. It formed in the section closest to the thermostat housing. "

He gave me a part number too. "The part number of the ground wire is 9008498006."

I'm guessing your friend is confusing the water neck with a thermostat housing it does sorta look like one. 90084-98006 is less than $10 at a Toyota dealer not even worth trying to restore the original.
