coolant bleeding
So I just finished replacing the fan switch on my 87 and I let it drain until there was no more dripping. I know that I lost over a gallon of coolant. The normal way to bleed seems to be by starting it with the radiator cap off but since there is not much coolant in the motor I am afraid to start it in case it may hurt the little 305. So is it safe to start or is there a better way? Thanks

Re: coolant bleeding
You're not going to hurt it.
Open the radiator and fill it until it's full. Be ready with more coolant and start the engine. It'll suck in what it needs. Refill as needed while the engine is running.
Leave the cap off and let the thermostat open a few times, topping off as needed. Then cap the radiator. Fill the overflow and shut off the engine. Done.

No need for "bleeding". Fill it as full as you can, if it will tolerate pop the cap off after the thermostat opens and fill up some more, fill the bottle, go pop a cold adult beverage. In the morning fill the bottle again. That's all there is to it.
Starting the car low of coolant won't bother anything. It doesn't heat up fast enough for that to be a problem.
