Shift I replaced the impeler and blow air through the lines, Although I never heard air come out the outlet port it always come out the inlet port. Someone told me the thermastat was not opening up to run the engine 30 secs. to 1 min., I did and still no water coming out the outlet port. Is there a special way to blow air out the outlet port or to check the thermastat?<br /> Thanks in advance and every resoponse is appreciated, Thanks 1st timer
