I have a 88 town car with the 5.0 f.i. motor. It seems to have a problem
with over pressurizing the cooling system. It leaks coolant from the nipple
at the upper radiator hose after it gets hot. I tried putting some sealent
and a new hose on, but that caused the leak to come out by the thermostat.
Once I took the hose back off and removed the sealent it resumed leaking
from the nipple by the radiator. The radiator in it looks to be original
and does have some small cracks in it that lose about a drop a day but
nothing serious. Could I need a new radiator or can you think of something
else wrong? btw..the heat works great and the thermostat stays closed until
it should open. Thats when I get my leak. Once the water is flowing
through the radiator.
Thanks for your help.
