1998 Chevy Blazer S10 with 4.3L V-6, 2-wheel drive, 4-door

Specifically, I need the torque specs:

1. Thermostat Housing
2. CAT front flange
3. CAT back flange

If you have a complete list of all torque specs feel free to post them here as it will help out others. I tried using the online Chilton's Manual from my local library but I'm unimpressed with the online edition of the manual as it's difficult to find specifics.

For the 4.3L the thermostat housing torque spec is 21 Ft-Lbs.

Now...does anyone know the Cat flange bolt torque specs?

How big were those bolts on the thermostat housing? Was there a gasket there?


This would probably have it, might try ebay first for a used copy:
