someone decided to use water instead of anti-freeze be4 i bought the car and now with the cold temps i noticed the other day when i was changing the radiator the hose was frozen so im assuming theres frozen water in the block too what should i do to get it melted and out of the engine? i didnt put any anti-freeze in the radiator yet but i did connect all the hoses i also bought a new thermostat and the gaskets for it which i plan on putting in after i get the water out. by the way the car is not on the road so it isnt being driven

second:
if the block is frozen like the hoses you may have a bad situation brewing. pup out the block core plug, and get the car near some heat. get the water out and get some 50 50 in it. freezing blocks can crack.

 

aight thanks but it wont let me change the topic.

where is the core plug? the engine is d15b7 with a z6 head

btw the top hose had nothing in it and the bottom hose had a little chuck of ice in it

 

bump

 

i cant remember on the d, but on a b series it is under the exhaust manifold on the front of the block.

 

i juss looked on the web and it looks like its in the same spot on the d http://www.autozone.com/addVehicleId...00c15280061770 look at the second pic

 

juss tryed to take off the bolt with no luck with the air compressor even with it set to 150psi my buddys going to bring a breaker bar and try to get it off.

also i dont think the water froze in the block now a little water was in the radiator and i drained it, it was from when i started the car the other day for a few mins
