It is a lot safer to do it that way. There will be no pressure in the system when it is cold. So the likelyhood of scalding yourself is at a minimum.
yes, should never add coolant to cold engine
Add coolant to the full cold line on the coolant reservoir when engine is cold.
The coolant add/overfill jug is on the left side of the motor when your looking at it. Add coolant up the closest line towards the top, and only when the engine is cold.
The coolant level is set by the level in the coolant reservoir. There is a line for the level if the engine is cold and a line for if the engine is up to temperature. You should fill it to the corresponding line.
Your engine should be cold ( to be on the safe side) when adding antifreeze/coolant. i let the car sit overnight and then add it.
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
Add coolant, with a cold engine for safety, through the "radiator" cap in the upper hose.Add coolant, with a cold engine for safety, through the "radiator" cap in the upper hose.
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.
It should be all the time in the container. It has special marks MIN and MAX, the coolant level should not be lower than the MIN mark and not higher than MAX. You have to add coollant when the engine is cold.
When the engine is cold you can add to either the radiator or the coolant recovery bottle.
When your engine is cold add coolant to the coolant reservoir so it is up to the cold mark
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
