My intent is to drain the ENTIRE cooling system, refill with plain water,
run engine, drain, refill again with water and Prestone Super Flush (active
ingredient = sodium citrate) run, with heater on until engine has been hot
for ten minutes, drain, fill and rinse hot, drain again and refill with
coolant (70%) and H20 Thanks, Neal
Common taurus problems:
Water pump. Bearing wears eccentric and impeller scrapes on
housing. If your pump has never been replaced, i would.
Thermostat: i would replace it for good measure.
Radiator: not uncommon for them to leak from the seams.
Looks close for wetness at the seams. The end tanks are crimped
on to the core. I have also had one leak from a crack in the end tank.
Look for wisps of vapour when hot. Radiator replacement is the only
solution there. (or rebuild)
Fans: sometimes the relay module can cause erratic fan operation.
The relay module is above the radiator.
There is a temperature sensor that controls the computer and the fans
too which could cause a problem.
New hoses are a must if your doing some work.
Check the oil, is there any water or milky stuff in it?
Although unusual, its not unheard of for a 3.0 to have
head gasket failure.
