For those that dont know i have a h22 in a accord. Anyway ever since i rebuilt the motor my coolant keeps going low. I checked the oil and NO water is gettign in the oil and I also checked all around the block. there are no leaks. The only place i see coolant is around the overflow bottle. I replaced the rad cap thinking it might be bad..... But everyday i have to add like almost a quart of antifreeze. but the overflow bottle stays full.. OVER full infact. Also when i realy get on the gas hard the temp gauge goes fully hot..... and the heater starts to blow cold air..... normal driving it runs normal temp and the heat works well... These just dont make sense to me. Is it possible that there is a blockage in my system? or any other thoughts would help.

 

all i can think of
HG?
cracked head?

 

put ur rad fan on constant. mine was off and it kept heating up cuz the fan wouldn't even turn on. then it over flows in the over flow tank dripping all over the floor n ----. especially when i gas it. turned it on constant n problem fixed!

 

Sounds like a air bubble in the cooling system to me.

 

These guys already said it, but try to bleed the cooling system really good. If it keeps happening I'd say hg. Good luck.
