Sounds like the thermostat is stuck open. Replace the thermostat.
There is no radiator cap, you must fill through the coolant reservoir.
Yes, all of them do. The most common liquid that conducts thermal energy is, of course, water. We put water - with a little ethylene glycol (anti-freeze) - into the radiator of your car. When you start the car, the engine gets hot, because of the gasoline and air exploding in each cylinder. Water running through the cooling manifold picks up the heat and cools the engine. The water runs through the heater core of your car and some of the heat is transferred to the air blowing into your car. The water then goes back into the radiator, and the heat from the water is transferred to the air going through the radiator. The now-cooled water goes back through the engine.
if you can read voltage in the water of a radiator , then there is a problem and the water needs to be drained and flushed and new antifreeze installed . if you are using full strength antifreeze, it must be mixed 50/50 with distilled water only. never use tap water in a radiator ! Thanks Jim TAnother viewThere is a specific problem that can be checked with a volt meter, I do this every major service (spring and fall) I check coolant voltage with engine running to engine block and chassis.If you read more than the error level for the meter you have a ground problem and this is grounding through the cooling system and will damage the cooling system. Most likely the radiator
Drain existing coolant from the plug at the bottom or rear of the radiator Flush radiator with clean water until water runs clear Re-fill radiator slowly (to prevent an airlock) with a mixture of 50/50 water and antifreeze Run engine to normal operating temperature with heater on Re-check coolant level
has the water pump been changed. is the fan working correctly. sounds to me you are not getting enough cooler air through radiator. check the operation of the fan and that the radiator fins are not full of dirt and leaves
Through the radiator cap no... But it does allow the antifreeze to come out through the cap if the pressure gets too high.
you have a hole somewhere or replaces your radiator
then you should have your radiator flushed because you have rust in it. FYI: antifreeze can strip the paint off of your it you spill it. Also, you may need to replace your radiator if the antifreeze is leaking, it may be through a rusted/corroded portion of the radiator.
the antifreeze runs through all your water lines in your car . . . . you put it in your water tank or radiator
It is no longer necessary to add just water to a radiator in newer cars like the 2005 Malibu. An antifreeze that is half water and half antifreeze is usually best. Add the 50/50 antifreeze to the radiator overflow tank. It should be a plastic, see through tank hooked to the radiator.
Use a 50/50 mix of antifreeze and water and fill SLOWLY to prevent an airlock through the top of the radiator
In the top of the radiator or through the coolant recovery tank
If you mean the water in your radiator, don't drive your vehicle until it thaws or your engine will overheat because no coolant will be flowing through it. You should keep 50% antifreeze and 50% distilled water in your car radiator at all times. (maybe slightly more antifreeze in cold winter weather) Water in the radiator won't freeze with antifreeze mixed with it.
Either at the top of the radiator or fill through the coolant recovery tank
Actually, both are used. However, it is more common to pull air through the radiator towards the engine. This draws cooler outside air through the radiator. Pushing air from the engine towards the radiator means that you are pulling hot air from around the engine towards the radiator.
To keep your engine from overheating the coolant runs from the radiator through the hoses into the block and back through the hoses into the radiator where it gets cooled by the fan and the air and starts the process all over again.
