If the reservoir has a hose that travels to the top of the radiator, then it is filled with engine coolant. If the hose is not connected to the radiator, then it is most likely a windshield washer bottle.
Transmission fluid mixed with washing powder
There is a water reservoir tank that goes to the radiator that you can add the water to.
It hooks to the top of the radiator just under the cap. If it does not have a cap it still goes to radiator.
if its the same as the lhs 97 model its on the overflow reservoir not the radiator its self the reservoir is next to the firewall on passenger side mine has a red relieve valve on a silver cap
Put it back into your radiator. You have a head/ headgasket failure. You will need repair.
Both. The reservoir is the overflow. But in the event your radiator is low, your reservoir will back it up.
The coolant goes into the reservoir only that says coolant. You don't put it in the radiator.
The overflow hose, that carries coolant from the radiator to either a reservoir on modern cars or to the ground on older cars.
A hot radiator releases excess coolant through the spring-loaded cap in to the reservoir, and when cooled the partial vacuum created by cooled radiator pulls it back in. A reservoir should be only about 1/4 full cold on a system that uses a radiator cap, some cars have a pressurized cap on reservoir and no cap on radiator
Why does the radiator fill up the reservoir
It probably has a leak. Here's something to check - the radiator has a tube coming out to the reservoir, so when it gets hot and expands the coolant goes into the reservoir and should go back into the radiator when it cools, but if your reservoir has a crack and the coolant leaks out, well it's gone and can't go back into the radiator - this would cause a lot of loss of coolant.
