i have a 351 W, water pump hose is on the driver's side and goes to bottom of radiator, the thermostat hose goes to the top of the radiator.
which direction does the water go? if i had to guess, i'd say the pump outputs to the bottom of the radiator. and the water from the radiator enters the block at the thermostat. is that correct?
i have a small leak. it appears to only leak about a tablespoon a day, and only when the engine is cold. i've replaced the thermostat gasket three times, the water pump gasket once, and then replaced the water pump and gasket once. i've never seen any sign of steam when the engine is hot, and don't smell hot coolant. and the leak will not be observed the day following a drive, it takes about two or three days to appear. i've yet to have to add water to the burp tank due to low level. but the leak is green antifreeze.
allan suggested Barrs radiator treatment, done that twice.
i kinda think it is leaking from the thermostat, maybe so slowly that it evaporates on the hot engine, and takes two or three days to leak enough to spill over where ever it is pooling before hitting the garage floor.
my next step is going to be a new thermo housing, unless some of the forum wits offer a suggestion.
all wet in Louisiana.
thanks
