A few years back a buddy of mine dumped his radiator on a Eclipse telling me it was running hot, and there was a obvious brown rusty look to the coolant. He told me he believed the previous owner had used water and nothing else in the radiator (thus the rust) and asked me to run him up to the grocery store, he came out with 3 jugs of CLR "Calcium Lime Rust". Upon returning to his garage
I watched him dump all three into the core and then topped up with water. He put the cap on and we took the car for a 15 minute drive,He then parked and let the fan cycle a few times he shut off the car and pulled the lower hose. I have never seen anything that foul come out of a cooling system... After draining he continued to refill and dump the core (starting and stopping the car).. When he got to the point that the water ran cean and clear out of the lower hose he finished letting it drain, mixed propper coolant and installed a new thermostat. topped up and declaired victory. He traded the car off within the year so i have no idea if there may or may not have been any longterm adverse effects.. I do know the car continued to be his DD for atleast 8 months after this little venture, and i never seen or heard another thing about the cooling system..
something i read in another post reminded me of this, thought id share the story.. I would have probably never thought to run CLR through the cooling system to clean it out..
think there was any damage from running this chemical in the system ?
