Hello Folks,

I often do maintenance work on my car and every time I take a bolt or nut off I am looking everywhere for the torque specs, I have piled a compilation of the most used ones, It will be interested if you guys can contribute to my list so whenever I need a torque spec I can come here!

This is what I got so far:2007 Lexus GS 350 RWD:

Oil Filter: 25 Nm (255 kgf-cm, 18 ft-lbf)
Oil drain plug: 40 Nm (408 kgf-cm, 30 ft-lbf)
Rear Differential drain plug: 49 Nm (500 kgf-cm, 36 ft-lbf)
Rear Differential Breather plug: 21 Nm (210 kgf-cm, 15 ft-lbf)
PCV Valve: 27 Nm (275 kgf-cm, 20 ft-lbf)
Wheel Lug Nuts: 103 Nm (76 ft-lbf)
Spark Plugs: 21 ft-lb for 14mm plugs (NGK)
Front Axle Hub Nut: 294 Nm (2998 kgf-cm, 217 ft-lbf)
Rear Axle Shaft Nut: 290 Nm (2957 kgf-cm, 214 ft-lbf)
Stabilizer bar link: 27 N·m (275 kgf·cm, 20ft·lbf)

 

I'll put this in the DIY Section for other members.

I usually just torque it til i am comfortable, but this is a much better idea.

Do you have the torque spec for the Throttle body nut and bolts? I had to remove it to replace the spark plugs this weekend but couldn't find the specs.

 

for Throttle Body it's 15 ft·lbf for both bolts and nuts

 

What's the torque for the 4 nuts holding the engine to the subframe, anybody know?

 

I'll look when I get home tonight and post the values. I have an F Sport sway bar kit waiting to be installed and I know the instructions list those torque values because those 4 bolts must be loosened to facilitate the installation of the front bar.

 

You mean nuts? To change swaybar just gotta remove the oil filter housing if i recall correctly. But maybe engine needs raising too I forgot. Btw when you raise the engine it makes the big tube pop off from the air filter box..

 

Have you installed F Sport sway bars? I have the detailed Lexus instructions right in front of me. This may be specific to the AWD model which is what I have. There is no mention of removing the oil filter housing. There is no mention of raising the engine whatsoever. The subframe mounting nuts need to be loosened, allowing the subframe to drop down slightly at the front.

The torque specs are as follows:
Front subframe mounting nuts (1 per side) : 123 ft/lbs
Rear subframe mounting nuts (1 per side): 122 ft/lbs
Rear subframe mounting bracket nuts (2 per side): 37 ft/lbs

 

Anyone know the torque specs for the transmission drain plug, fill bolt and level bolt?

Thanks

 

Level bolt 15lb / 20nm
Fill bolt- 29lb/39nm
Drain bolt 15lb/20nm

 

Thank you Sir, I will use these next time I do the service. This time it was the old fashioned way, by feel. Lol.

 

Looking to change struts on my 06 GS430. Anyone have the torque specs for the relevant nuts? I'm totally new to car repair , this will be my first DIY
