Another Running HOT Thread

I will add my personal experience. I replaced the original 361 with a new 400 in my Charger, and I needed a drivers side exit for the lower rad hose so I bought a Mancini aluminum pump housing and high volume pump. Everything else in the cooling system was the same right down to the thermostat. My car acted like yours and would overheat and puke coolant in less than 10 miles. I pulled it apart and replaced the pump with the original from the 361. So far I have driven the car three times and the temperature is back in the normal range. I am not here to argue thermodynamic theory. I have no idea why the high volume pump did not work. I am posting from actual experience.

Since the cooling system is presuerizd, to some extent, via the 16# (13#) radiator cap, there is physical phenomenon that all aspects of the system are pressurized, to the same alue, including all he components of the system.....upper, lower ,heater hose, block and heads.....to the same value, depending on overall surface area (#'s / square jnch). And at normal operating conditions, the lower radiator hose is subjected to overall nominal system pressure. IF AND ONLY IF THE LOWER RADIATOR HOSE IS SOFT AND FLABBY AND AT EXTREMLY HIGH FOWS COULD IT PARTIALLY COLLAPSE. BUT DUE DUE TO MODERN PHYSICAL HOSE COMPOSITION. THS IS HIGHLY UNLIKELY TO OCCUR (with/without the spring. Old wives tale #3. The phenomenon is called suction pressure. Trite explanations just don't cut it, in spite of what the general populist believes..........just my opinion of course......others will likely disagree.......

Bob, if you spent more time editing out your typos/spelling errors instead of the best time to randomly YELL and startle the hell out of us with cPTSD your point and lesson would come across more clearly!
