Hello Everyone, I tried to search but couldn't find the answer, so I hope you can help. What is the Torx Socket Size for the 2 bolts holding the coil pack wire?

If it's the same size as the screw on my ES300 (which it should be), then it's an E6. But, wait for someone to confirm.

It's a E5 or E6. I remember I drove around trying to find one last summer and ended up just using a pair of vise grips to break the bolt loose.

Thanks guys. I will order a whole set, and will report back the exact size as soon as I got it.

It' E6 but prepare for the shear-off. TOYOTA use steel bolts on aluminum alloy(valve cover), the result:TROUBLE!!
I grind the head of bolt to square and use a adjustable wrench to get it off.(vise grip didn't have enough grip)
I put a 6mm bolt with 10mm head back,it's much easier for next time to remove it. I really don't understand why TOYOTA do that ?? Can anybody enlight me ?

Thank you guys. It's E6, but the bolt is very soft and it sheared off one head. Hopefully I will have more luck removing the two torx bolts on the water pump.

Please let me know your outcome. I'm going to change my water pump this spring, if the shear-off is so frequent, I'll jack up engine and use stud remover. Please info. me whenever you're done. Thanks.

I will report back when I have it done.

are these on the valve cover? should i get the E6 or just go at them with something else since they will shear regardless?

If memory serves me correctly, I believe they were the same bolts on both the valve cover and the coil pack.
