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 )
The raiator is a type of system where all fluid is added to the reservoir instead of the radiator directly, look for the reservoir and you will have found your radiator cap.
the overflow res. cap is the radiator cap on the 97 cavalier
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.
To put in more antifreeze in a 1995 Plymouth Voyager, located the reservoir near the radiator. Antifreeze is no longer added directly to the radiator. It is put into the plastic reservoir that is labeled radiator or coolant overflow.
Remove the radiator cap and add it directly to the radiator. Then fill the overflow reservoir to the full mark.
depends on the type of vehicle
Yes you can.
you don't fill the radiator directly, there is no radiator fill cap. you fill the overflow reservoir and it keeps the radiator full. overflow reservoir is spherical plastic near firewall. power steering reservoir is up front near battery.
The year, make and model would be helpful.If the radiator doesn't have a typical radiator cap then look for a plastic reservoir mounted else where under the hood.
When your engine is cold add coolant to the coolant reservoir so it is up to the cold mark
Both. The reservoir is the overflow. But in the event your radiator is low, your reservoir will back it up.
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.
