Andy is right about the townsend flushing instructions. tricks like removing the old thermostat before flushing and sticking the garden hose into one of the heater hoses make the job easier.
What you must be careful of, is the removal of the thermostat housing bolts. They freeze up due to corrosion and you can easily round the bolt head or worse yet, strip the aluminum threads in the cylinder head. Then you get to do your first heli-coil job to restore the threads. Do not use an open end wrench for the initial loosening. Use a box end wrench or better yet, a six point socket(12mm??). Spray some good penetrant like wurth's or pb-blaster around the bolts the night before. Then, with the socket on an extension, no ratchet yet, place the socket over the thermostat housing bolt heads and give the end of the extension several sharp taps with a hammer to loosen the threads. You should then be able to remove the bolts successfully after that. If you still strip the block threads, the heli-coil repair is not all that bad.
When you take the thermostat housing off, carefully clean the mating surfaces without gouging them. After you have flushed and are ready to put the new thermostat in, make sure you have the little holes in the thermostat lined up on the high side and use anti-seize on the bolts when you reinstall and don't over tighten.
