Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
3. Install the thermostat housing bolts and tighten them to 18 ft. Lbs. (25 Nm).
4. Install the radiator hose to the thermostat housing.

Before trying to replace thermostat, really hard to and about $500.00 labor to get done, try this unplug both electric cooling fans, start engine and let idle a few minutes, heater might work I think it might be a signal problem from coolant temp sensor, hook fans up, don t leave unplugged or engine will over heat

The directions were correct! I did mine recently without removing the crossover pipe.I needed a stubby ratcheting wrench, a coat hanger (to hold the bolt) and some patience. But it's an expensive fix at a garage and a time consuming one at home, unless you have the proper tools and a garage.
