How to are in the S-10 forum.

10 USA bucks can go a long way on a good stat.
Gates has a extra good no fail stat that sticks open if it goes bad and does not burn up engine.

Newer stats have a rubber sealing ring instead of a flat gasket.
Install stat like the old one came out.
Thermo bulb towards engine.
Also sometime you need to bleed air at a hose on upper intake area intake or heater hose.
Good Luck
