If there is a cap on the radiator you can check to see if the radiator is full ,
and if it isn't , " top up " the engine coolant . Otherwise , you check the
engine coolant level at the engine coolant reservoir when the engine is cold
and maintain the level at the cold mark
Don't! Most cars have a reservoir for radiator coolant ... add liquid to the reservoir. Opening the radiator cap introduces air into the sealed system ... you don't want air bubbles in the cooling system.
Add the coolant into the coolant reservoir. Be sure the engine is cool when you remove the cap off the reservoir.
A lot of vehicles don't have the radiator cap on the radiator , they use a thread on style cap on the engine coolant reservoir ( that is the pressure cap / radiator cap )
When your engine is cold add coolant to the coolant reservoir so it is up to the cold mark
To add water to the radiator on a new beetle, first remove the lower radiator hose. Then add water to the coolant reservoir.
You add coolant to the reservoir and in the radiator cap.
Under the right side of the false tank there should be a reservoir you can add coolant to that is connected to the radiator.
Coolant reservoir, or directly in the radiator. If you are having to add much coolant, you need to find out why. Serious engine damage can occur if it is leaking inside the engine.
You should add coolant with the engine off and cool, top off the radiator and fill the coolant reservoir to the cool or cold level. When the system is hot or running it will be pressurized and will be dangerous to open. You can however add coolant to the overflow reservoir at any time.
On a 2003 Ford Ranger : The 2.3 litre four cylinder engine has a thread on cap on the engine coolant reservoir , that is the pressure cap / radiator cap ----------------------------------------------------------------------------------------------------- On the 3.0 and 4.0 litre V6 engines , I believe there is a radiator cap on the top of the radiator , but with the engine cool you should add engine coolant to the engine coolant reservoir - it has a cold fill mark
It doesn't have one. If you wanna add more coolant you will have to do it with from your reservoir.
I believe you add at the engine coolant reservoir , and that the thread on cap is the " rad " cap
