This will be a three part question. I have a 2001 Ford Taurus SES that I've had for 14 years and suddenly the coolant reservoir is milky with rust in it what could it be, and why, what must I do to fix it?
2001 Ford Taurus SES w/S in the middle of the VIN
I have flushed the coolant reservoir, but the milky rust substance has returned. I need help before the semester starts, so I will have a reliable car to get to and fro classes. It will be a blessing if I get my car fixed before the 27th of this month. I also have a 2001 Taurus SEL for parts if it will help thanks community.
You need to flush to entire cooling system. Use Prestone Super Cooling System Flush.
Flush the system and have it pressure tested. Milky could be engine oil and it could have an issue with head gaskets. Does the engine oil look okay or is it milky looking also?
I'm with Bob on this one, milky coolant usually means oil, and on a Taurus that is a known head gasket blowing engine doesn't look good.
Especially if it's been overheated! HTH. - Jim

Mechanic put Dex cool cool in my system mixed with old green
It's not head gaskets you would know
