You may notice that the color of "red," being described is very close to the color of rust. If that is the case, then 1+1=2, right? If the cooling system is properly filled with an appropriate mix of coolant and water then this should not occur. There are three elements required to produce rust... Iron, water and oxygen. If the cooling system has not been properly filled (to include purging all the air from the system) then rusting can occur. This can occur within the coolant passages of the engine block or within the water pump housing. Since the passages inside the radiator are typically copper or aluminum (as well as in the heater core) the source of this "rust colored residue," is coming from within the engine block itself. It can also indicate a poor seal. For example, the radiator pressure cap seal. When the engine begins to cool, the molecules begin to contract and you end up with a sort of a vacuum. Air can be introduced into the cooling system, past the radiator cap, as the fluids begin to cool. Normally, one would notice the opposite effects of a bad seal while the fluids are hot and creating pressure because the fluids would likely leak out. When pressure is lost in the cooling system via a leak, the boiling point of the coolant decreases and overflow occurs more easily. Try flushing your cooling system and refilling it. Ensure to follow manufacturer guidelines on bleeding the air out of the system. If possible, have the cooling system pressure tested to check for possible leaks. If that's not an option, then monitor the coolant in the engine and if the red discoloration continues (after having bled all the air out) then start investigating all the seals for leaks. Hope this helps.
An overflow tank is a bottle that holds coolant that expands and leaves the radiator under driving conditions. The Coolant will go back into the radiator as needed.
Put it in the radiator but also make sure the overflow tank is full. Follow the overflow tube from the radiator and you will find the tank.
No.
You have to fill the overflow tank as the radiator does not have a fill cap. Run the engine as you fill the overflow tank but just up to the marks on the tank.
the water overflow tank
yes
coolant overflow/reservoir tank
Its on the overflow tank.
You fill the radiator through the overflow tank.
: The overflow cap (radiator cap) is on top of the tank that sits on top of the dr. side fender under the hood.some of the newer cars do not have a "radiator cap" it goes in to the overflow tank . i would not suggest using radiator stop leak because it can clog up the radiator and heater core on the car if you must use it only as a last resort.
there is an antifreeze overflow tank, look on the radiator next to the radiator cap and there should be a smallish hose, follow it and you will find the tank.
Overflow tank only
