Both. The reservoir is the overflow. But in the event your radiator is low, your reservoir will back it up.
Why does the radiator fill up the reservoir
look on the bottom reservoir at the back
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
Yes- coolant reservoir is designed to accept excess coolant - As coolant heats up it will expand and flow to the coolant recovery tank (reservoir) and as it cools (contracts) it will be sucked back into the radiator
On the coolant reservoir. This is a plastic reservoir toward the back right of the engine compartment.
Add the coolant into the coolant reservoir. Be sure the engine is cool when you remove the cap off the reservoir.
It sounds like there's a leak somewhere. If it's not in the cap, it could be in the hose, or the connection, or the radiator itself. If you can't figure this out on your own, take it to a mechanic.
Overheating due to coolant going to the reservoir and not coming back to the radiator because of the bad cap.
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.
Fill the system by using the reservoir mounted on the back of the engine bay to the left of the power steering fluid reservoir.
It replaces coolant back into the system by drawing coolant from the reservoir that was pushed out into the reservoir during the heat up process.
