Default Help needed

Hello, I'm helping a friend of mine get his car back in shape. He has a 1994 civic with the vtech engine. The car started over heating and he found the radiator was bad. We replaced the radiator and the car still over heated on him. He claims to be losing fluid in excess but i see no evidence of a leak anywhere on the ground or in the engine compartment. I suspected a head gasket and had him turn the car over with the radiator cap off. water shot out of the radiator which confirmed my suspicions. The car runs fine other than the over heating so my question is.
Is this common on this yr car or could this be a cracked head and is there a way to check one from the other, meaning bad gasket or cracked head?

Thanks in advance.

Is there coolant in the oil or oil in the coolant? Any white smoke ? Did you replace the thermostat ?

Hi Tony.
First, yes the thermostat was replaced and it did help a very little. There are no visible signs of any problem ( white smoke, or coolant in oil and vise versa ) thats the odd thing. The car runs actually very good. The owner claims, before I changed thermostat, that it lost coolant rapidly. I saw no signs of leaking while car sat idling for only a min or so and no signs of anything leaking on the ground or in the engine compartment. That's the odd part. No skipping or steaming out the exhaust. The only thing I can think of is that the water is being forced out due to a over pressurized cooling system, while driving. As I stated, when he turned the car over for me with the rad cap off, new cap, water shot out of the rad about 6-8 inches , or more.
Any clues in there?

sounds like some thing could be clogged and your probably losing coolant due to that may be coming out the over flow ...is your passenger floor wet at all ? ......do this start the car and let it warm up and keep watching and listening,..as the engine pressurizes you should find a leak some where .

How often do you have to fill it up?
