Radiator coolant.
Yes you can put coolant right into the radiator. Just make sure it is a 50/50 mix of the correct anti-freeze and distilled water.
Never put just straight water in your motor. You want to top off your radiator first then top off your coolant in the reservoir. Water will rust your motor from the inside out.
Of course! The radiator is designed to hold a mix of water and coolant, but at a pinch just water will do. It's not a good idea to do this for too long though as it can cause corrosion in the radiator and engine.
The 1999 Wrangler is equipped with an overflow tank. The amount iof coolant to add to the radiator is slightly less than 2 gallons. Be sure to use either a 50/50 coolant (pre-mixed with water) or a gallon of concentrated coolant mixed with an equal amount of water. You will have about 3/4 inch of coolant left in the container when the radiator is full. The overflow tank is there to hold coolant when the radiator gets warm and needs to expell some of the coolant. So just fill the radiator with coolant. You'll know when it's full.
Check the radiator hoses. The coolant is either leaking out of the new radiator, or it is coming from a radiator hose. The water pump may be leaking. Hose clamps may be loose.
You should add a 50/50 mix of anti-freeze and water.
With the engine cold, put it in the radiator just to be sure there is no air gap. Run it for a short time until it gets warm and coolant begins to circulate. Then install the radiator cap and put coolant in the overflow to the coolant level line.
You don't "fill up" the water pump. The water pump is just a pump that moves coolant throughout the engine cooling system. You add coolant at the radiator or the coolant recovery tank.
NO just Coolant
The coolant temp sensor on a 97 Buick Century is on the side of the radiator. It is just below the radiator cap.
no cap, just the coolant tank, add to this to add coolant../
It is on the bottom of the radiator just below the lower radiator hose.
