DEFINE WHAT IS COOLANT USED IN CARS

WELL YOU SHOULD HAVE 50/50 WATER AND ANTIFREEZE MIXTURE ADD MORE ANTIFREEZE.SOUND LIKE CAR LOW IN COOLANT.FILL RADIATOR UP RUN CAR TO THERMOSTAT OPEN ADD MORE COOLANT IN RADIATOR UNTIL COOLANT LEVEL STOPS.IF CAR STILL OVER HEAT REPLACE THERMOSTAT AND PRESSURE CAP.

FIRST DON'T EVER PUT WATER INTO YOUR ENGINE OR ANY OF ITS COMPONENTS. What you looking at is the Coolant resivour and your low. buy some 50/50 prediluted coolant and fill to the COLD line if the engine is cold, HOT line if you just turned your car off. Also wait until your engine cools and check your Radiator to see if you have enough coolant. If not, fill coolant to the opening neck, SLOWLY squeeze the top radiator hose until the coolant starts to almost spill out. top off to the top of the neck again and run your engine for 15 minutes and then allow to cool and check the level again.

First buy the pre-diluted 50/50 coolant, no water and mesuring required. Looking directly in front of the engine, where your headlights are, you'll find your radiator. On top you'll see a metal cap with some warnings on it about not opening it when hot. so when your enging is cool carfully remove that cap and add 50/50 pre-diluted coolant( DO NOT ADD ANY WATER) until its right at the neck of the opening. Next slowly squeeze your top hose coming off the radiator and you should see one of two things, some bubbles or coolant spilling out. add more coolant to top off, close the cap on the radiator. Next find your Coolant resivour, you can find that by following the small hose coming of the neck of the radiator cap. and fill to the COLD line. Run your car at idle for 15 minutes, allow to cool for an hour and repeat entire process to properly top off.

that is called the recovery tank and the level should not go down, if u keep seeing the tanks level drop then u have a coolant leak in the system, when u do top the system off ALWAYS USE 50%

Place a catch all bowl or whatever you have under the vehicle, open the valve at the bottom of the radiator, and remove the radiator cap. Wait. There ought to be a lot of dribbling.

You can shake the car from side to side after the flow stops to try to slosh a little more out.

You can just live with the little amount that remains, or, you can close the valve, fill with water, run it for about 30 seconds, then drain that water, too, then close the valve.

Put in the amount of coolant recommended, then top of with water. For instance, if it recommends a 50/50 mix, and is said to hold 6 quarts, pit in 3 quarts of coolant, the top off with water. Replace the radiator cap.

If you have the Northstar engine do not use ordinary coolant (the green stuff).You must use a long life silicate free coolant.
Dexcool was the original coolant used but there are many other brands to choose from now. It is usually a red-ish or pink-ish color (yellow if you choose the Prestone brand).
To clarify, make sure it states LONG LIFE or 150,000 miles on the label but more importantly it MUST be SILICATE FREE.
Mix the coolant 50/50 preferably with distilled water but clean tap water is ok.

You should use a 50-50 mix of water and anti freeze. Top it off and start car and check that level is fine when warmed up.

they make a fill funnel for just that resopn so no air stays in rad. you can buy a 50/50 mix or mix it yourself but 50 50 is about the best.

The yellow cap wit coolant on it should be the fill cap, the take should also have low and full lines on it. Most places int the states you should do a 50/50 mixture of coolant to water.

This means your car is running too hot. After it cools down check the coolant level and top off as necessary, a 50/50 mix of water and coolant/antifreeze should be fine.

If it it blinks again it is one of two thing, the coolant level is low or the coolant temperature is too high, too high could be an improper water to coolant ratio, i.e. too much water.

Best of luck!
