I have an 86 Supra Sunsport that I have a few questions about winterizing. I used to have a 92 IO Rinker Captiva that we just drained the block and rain antifreeze to the out drive and stabilized the fuel and we were good to go. I'm not real big on filling it all full on antifreeze since you have to worry about the thermostat opening up and the thought of any liquid in the block at all just makes me nervous. Any other things to drain other than the block and the exhaust manifolds? Any other tips or guys that do it without antifreeze and just drain all of it? anything will be appreciated. Thanks in advance.
