If I take the exhaust manifold off will I have enough room to drill out what is left of the existing threads? Also what is better hand tapping or with a drill? I have the Heli-coils, when I went to Toyota to pick up my new OEM thermostat, I enquired about the Heli-coils and they had some extra and just gave them to me. Napa sells a kit for $40, but I think I can get away with doing it for less. I just need to get the right tap, 10Mx1.25. All help is appreciated, thank you.

I would say try to back it out 1st....
my neighbor did this for me when i snapped on on the thermostat housing but eneded up drilling it out...but i would say soak it with pb blaster 1st and try a tap, then drill.
i'd wait to see what others say too....

They did have the 2-valve t-stat, part # 90916-03070. That was like $35-$37. Interesting how it has two valves. Has anyone used that one before and how is it going for you.

T-stat is in and works, now I just am looking to borrow a right angled cordless drill to do the heli-coil. The truck sounds great besides the exhaust leak.

Well this should have been checked before assembling the motor. But now that the motor is assembled, I have to become creative and tap out the head. I will be doing this on friday, thinking of rotating the engine to get a better look at it.

The 2 valved thermo thing....
Isn't it just an extra hole drilled to allow some movement and lesson pressure "just in case" ?
I thought there was a write up on these little holes somewhere on here?
Same thing or am I mixing lemon aid and milk again....
