05hynday accent blowed radiator and got water in plugs now won't start what could it be 1.6

Blowed radiator? I guess you mean that the head gasket on the motor blew out and let coolant into the engine and combustion gasses into the radiator.

Same as any other engine. The head gasket can blow between two cylinders, in which case compression in each will be very low, or it can blow/leak water into oil such that the oil will be milky looking, or it can blow to the outside and show as leaks. One good way to test individual cylinders, is to remove a spark plug and screw in an air chuck made for this use and hook up compressed air. Is you then see bubbles in the radiator coolant gasket is leaking, or if the dipstick blows out the leak is to the oil.

this is a picture of the engine bay

coolant color might be red if its an aluminum engine
square box is radiator cap

you follow the small hose below the radiator cap to find the
overflow bottle

with your specs about the plugs / check leads and distributor cap or distributor unit

Pull the plugs out and then crank the engine over if water comes out of the plug holes you have a busted head gasket which would give you compression in the coolant system thusblowing out antifreeze as well as overheating.

water in the oil will turn the oil brown like mud,is that what you see? if so,then you have a blown head gasket,do not run motor if this is the case as the motor wiil spin a crank bearing or lock up.are you sure about the water in the oil? look for real brown oil just like mud with bubbles on the oil dipstick. if the heats stopped working it may be because the radiator's low on fluid. look in the radiator for low coolant,if you can't see the coolant when you remove the radiator cap,it's low. with engine cool,remove the radiator cap 1st then start the engine. do you see steam and fluid blowing up frome the radiator? if so,you have a blown head gasket in the motor. head gaskets can blow and leak water into the oil or oil into the radiator. or blow and leak into the exhaust sysytem and blow coolant out of the tail pipe. three different ways for a head gasket to blow. usually the head gasket only blows when the engine has been run really hot!!! hope this helps.thank you for choosing fixya .com

If the water tends to keep going down then there has to be a leak somewhere. Try also looking at the hose coming from the overflow tank and see if the hose might be kinked. You might also be blowing antifreeze out the tailpipe. Take a look and if there is bluish white smoke then you have confirmed that theory,

check your glow plugs they may be damaged or dirty

replace the radiator call 1-800-radiator ive bought there best prices i think

If you are trying to add engine coolant to the radiator (which is what I believe you are trying to do) make sure that it is a 50% water 50% antifreeze mixture. If you only add water, it will evaporate quickly and in cold weather it can freeze and blow the radiator. When you are adding your mixture always make sure the car is running (in order to not crack the head of the motor) and if you have a funnel great if not try to get it in as best you can. When you open the hood right near the front (near the headlights) is the radiator and there is a yellow or silver cap. Take that off and that is where you add the mixture. As the car gets warmer it will begin to start bubbling so at that point replace the cap, and later when the car cools refill more. You can also use the overflow tank which should be on the left side towards the back but only fill it to the line that is indicated for hot/cold (it will be stamped somewhere on the plastick overflow tank.
