Does not have one. Just a reservoir.
On a 2002 Ford Explorer the thread on cap on the engine coolant reservoir is the pressure cap / radiator cap
On a 2002 Ford Explorer : The thread on cap on your engine coolant reservoir is the pressure cap / radiator cap
On a 2002 Ford Escape : The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap
On a 2002 Ford Explorer : The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap
On a 2002 Ford Expedition : The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap
On a 2003 Ford Ranger : Since you are asking this question I assume you have the 2.3L Dual Over Head Cam four cylinder engine . In this case the thread on cap on the engine coolant reservoir is your pressure cap / radiator cap The 3.0L and 4.0L V6 engines have the radiator cap on top of the radiator
On a 2000 Ford Ranger : With the engine cold the radiator should be filled to the seat for the radiator cap and the engine coolant reservoir should be filled to the cold mark
The engine coolant reservoir has a thread on cap which is the "radiator " cap for the 4 cylinder engine
For a 2002 Ford Taurus : The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap ( I believe the Motorcraft part number is RS-103 ) it's a 16 PSI cap
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
The radiator cap is on top of the radiator.
Not very far. Without the cap on your radiator your cooling fluid will not flow properly and you can have a serious problem with overheating.
