quick question guys when i drained my engine block and also replaced the t-stat and after you fire it up and hook the garden hose up to it how do you avoid the engine from getting an airlock in it .has anybody put a small hole in the t-stat to prevent this or does it not happen on a boat .i would think once you drain the block the engine would get an air lock in it .
this is for a 1988 351 ford indmar engine. just curious i am new to all this stuff i just purchased the boat last month . i don't see how the air can escape the system .water can come in the impeller pump and go through the water pump .but it will get stuck jammed up at the t-stat .and how will the t-stat open if the water can't get to it because of the air bubble. and all this i am thinking is because you can drain the block, giant air bubble in the motor now .
just curous. any info would be great .
