I don't have an inch-pound torque wrench.

Guess I should pick one up.

By the way, nuts to paying $109 for an adapter., which I can't find on the ZZPerformance site anyway. After having this apart, I think I can make one out of 1/2" aluminum plate. and use the stock TB.

If I can't, I haven't been a car guy for 40+ years.

Any got a junk n/a throttle body they want to sell?

It is 89 inch lbs. I just did mine.

As for the coolant plug, zzperformance sells the exact plug to fit our coolant passages. If memory serves, it'* less than $20...

Default torque

My intake bolts were loose after just a month of driving. I beleive there is tech info that ups the torque from the original spec.
Your leak should be solved Vital. Let us know.
As for the Dexcool, GM had an issue with their original supplier and is in litigation
with them. They then switched to the Prestone proprietary formula sometime in 2001.
I have always used Prestone products and have the Dexcool in my 96 SE and as well
as my Supra with no issues whatsoever.

I also have kept the Dexcool in. No issues whatsoever in any of my cars that have had it (97 Cavy with 184K when I sold it, my C1500, the Bonnie, and the 'Hawk). As long as the fluid is topped off it'* fine.

It'* been 4 days/350 miles since I retorqued the upper and it'* holding up real well! I don't have that puddle anymore and the lower intake is drying up where the coolant was running down. The back side of the upper I think is leaking. There'* a light dirt/moisture mix in the coolant vanes of the lower intake. Nothing is puddling, but it'll only be a matter of time before it does. Hopefully it'll hold out until somebody makes an aluminum discovery!
