My car's coolant level is below min level. Can I refill it or do I have to get it flushed before a refill?

Answer 1

Of course you can refill it.

First of all, you do not have to flush out the water (unless you notice that the fluid iniside is really dirty or rusty, in which case, your radiator or piping may have rusted).

Below is a list of liquids you can pour into your radiator :-
1. Radiator coolant (if you are feeling rich)
2. Distilled water (if you are feeling not so rich)
3. Tap water (this is fine, if you are feeling economical)

Beware: only open the radiator cap when the engine is cold and be sure to shut off the engine as well.

Answer 2

there aRE SOME THINGS YOU NEED TO CHECK YOURSELF OR HAVE TESTED. THIS IS NOT A SIMPLE QUESTION. It could be as simple as topping off the overflow tank, but you need to find out why the level is low. If you can do this yourself, here's what you do.....refill the radiator if it is low. make sure it is cold to the touch before you remove the cap.. remember to prees down before you turn the cap, and look at the markings on the cap, they will tell you when the cap is properly lined up to come off.the cap will have to be turned twice as the cap has a stop when you get it halfway offf.it is usually a 1/4 turn to the first stop. this takes the pressure off the spring in the cap. the cap holds the cooling system under pressure only when it is warm or hot.it self pressurizes when hot..that is why you do this when cold.no pressure. when you get the cap off, fill with antifreeze diluted 50/50 with water.you can buy this kind already mixed but it isn't economical. so fill it up. then if you can borrow one, use a pressure tester for your radiator cap and the radiator/cooling system.If you can't do this yourself, just find a good mechanic that knows how to pressure test your cooling system. when your cooling system is pressurized to 16 lbs, you watch listen and look for leaks. keep in mind that a blown head gasket and a cracked head will not leak out but in the engine. so after your pressure test, fill everything up to the proper level and start the engine and watch the tailpipe for water or steam.. if they are present you have an internal engine problem. In response to flushing the answer is no. flushing the cooling system has absoluetly nothing to do with the coolant level.

Answer 3

You can refill it. But if it is a steady leak you should get it checked, and if it has been a while since you had it flushed it would be a good idea to have it flushed, it will help keep the engine from overheating.

Answer 4

Buy pre-mixed coolant, 50/50, at the auto parts store and add until you are at the proper level. There will usually be a line showing cold level and hot level. Add accordingly. Make sure you either get the universal coolant, or the type called for in your vehicle. If in doubt, ask first.

Answer 5

Just refill it with 50/50 mix.

Answer 6

you dont say what kind of car as some makers cars are leakers from the rad seals. to test your system the car must be cold then pressurised to 20lbs if no leak is found then its the bad news. also check the rad cap with the same tool. a little sweating is ok but more than say 1/2 liter per month is too much. alluminun/plastic rads can be recrimped

Answer 7

sounds like a negative activity to me. possibly the cooling gadget desires air bled from it and is gurgling from the air wallet. i ought to assume the coolant element to be on the whole of the radiator at the same time as at operating temperature. There should be coolant interior the overflow tank. If there is no longer flow again to the service branch and lead them to stress try your cooling gadget for leaks.

Answer 8

refill it
