Hey, ok i dont want to sound stupid but well, stupid question that matter to me.
This week i went ahead installing my knock alert/knock sensor at the bottom of the block in the coolant drain plug.
Before to remove the drain plug i thought coolant will leak and make a mess.. so i removed the radiator cap, squeezed the hoses and then put the radiator cap back on(hopefully creating a small vacuum inside the cooling system to prevent coolant from leaking out the drain plug too much).
Now, i dont know why, but when i removed the drain plug no cooland leaked at all, it looked like there where no coolant in that part of the block.. but the plug end LOOKED to be wet/oiled with some coolant.
Now i am confused, maby its normal coolant wont drain out because the radiator cap is on or maby the passage is plugged inside the block?
Why is that?, is it because the engine hasn't run since a few month?, is it because i somehow created a small vacuum in the coolant system that did prevent coolant to drain out by the drain plug with the radiator cap on(hopefully that is the reason)?, should i worry or should i live it that way as the engine has no overheating problem?
I guess next time i get it started i get the infrared temp indicator and check for temp variation on that part of the block?
If someone tell me its normal, coolant wont drain when the radiator cap is on that will make my day
thanks you
