2000 Toyota Tundra

Reader Question: Sir,

I have a 2000 Toyota Tundra V6. It makes a grinding sound when idling. When you rev the engine up it quits the noise.

I have replaced the timing belt and water pump. Almost sounds like its coming from the transmission but drives and shifts fine and keeps good oil pressure!

Any ideas before I spend more money on something I do not need.

Thanks.

Gary

Hey Gary,

I would remove the fan belts then start the engine and let it idle to see if the noise goes away. If it does, it is most likely an accessory like the AC compressor, which is causing the noise.

If the noise is still present with the belts removed, it could be an internal engine, valve train noise or something with the transmission or torque converter.

Blessings,
Austin Davis
