How to get rid of the tap water from the engine block after flush?
After making a cooling system flush with tap water,there is a 50% of tap
water(and even more)that remains in the engine block.
I would like to have only distilled water in the system(before i will add 50%
concentrate green coolant)
My question is:if i pour a distilled water (about1-2 gallon) through the radiator
bottom hose(while thermostat is disconnected):
1)Will the distilled water push all the tap water from the block out of the
radiator's bottom outlet?
2)Or will the distilled water will be mixed with the tap water in the engine
block and will pushed out together from the system,as after pouring 2 gallon
of distilled water there will be,actually, a mixed distilled water+tap water in the
Thanks in advance.
i think it would mix no matter how you did it but to get most out i think i would hook a shop vac up to the lower hose and turn it on with the upper hose off i think it would dry it out after some time
Well if you do it this way, one & two gal. of distilled water probably wont flush all the tap water out, I would figure it would take a bit more, but then just adding 50/50 mix you would find that it would not be strong enough for winter. You would need a couple of quarts of straight anti-freeze. There are drain plugs in the water jacket you could pull, they are lower in the system, but normally there not easy to get to.
Refer to adding coolant,i meant that i am going to add 50%(from the cooling system capacity)CONCENTRATE green coolant to the system and after that i will complete the rest with distilled water. This engine,unfortunately,doesn't have drain plugs. I didn't understand how the shop vac is going to dry 3+ litre of coolant? I also don't figure out why the tap water in the system will mixed with the distilled water and will not pushed out by them? If i pour the distilled water through the upper radiator hose(for example)the distilled water,supposed to flow through the thermostat(disconnected)through the cylinder head,the engine block,the water pump to the radiator bottom hose,doesn't it? It doesn't flow through the thermostat directly to the water pump and to the radiator bottom hose,while skipping the cylinder head and engine block passages,does it? So why the distilled water is mixing with the tap water rather than pushing it out?
ok 1st off why distilled water and not tap water all so the shop vac will dry the motor out completely ie not water at all in a motor 2nd if you are just trying to fill the coolant system just drain what you can refill with a gallon of strait antifreeze . then top off with 50 50 antifreeze. and tap water and distilled water will mix they are the same Distilled water is made by boiling water it is still just water
I don't know about the shop vac thing, but never thought even for a reason to try it, BUT I agree totally with you statement above, straight anti-freeze and top it of with 50/50
oh and by the way there is not just one path for the water to go the heads and block are an open cavity like say a tank so not just a hose or a pipe to follow i hope that helps you get what you need done
Pull water/coolant plug if you a so concerned. Also I always buy the straight ant-freeze and mix my own 50/50. You get 2 gal. for the price and if not a little cheaper, that 1
