My civic starts to spit the water out of the reservoir tank when I drive fast n I always have to b checking the water so it wont over heat n e one know y its doing this thanks!!

 

You may have a blown head gasket. Do a leak down on the engine to see what is going on. Also Honda around your year had a defective block recall. You may want to look into that as well.

 

If it was the headgasket wont there b water in the oil wat would b wrong with the block

 

There is more than one way to blow a head gasket. One way is water leaking into oil. The other is water leaking into cylinders. You seem to have water leaking into cylinders. This also means when you drive fast the cylinders push air back into the coolant system and push the water out of the reservoir.

 

Is there a way to check if water is in the cylinder and how can I fix it
