When do you add coolant to the radiator?
While the engine is still idling, add coolant to the radiator until it’s full and shut the engine off and install the radiator cap. After a half hour, check the level in the coolant reservoir and add coolant as required. The inquires above are to determine your car’s cooling system configuration.
What should I do after filling my radiator?
Anti-freeze is very toxic if ingested. You can make a funnel out of an old plastic milk bottle or oil bottle. After you fill the radiator, the fill the overflow reservoir up to the cold mark only. Do not fill it up. If your radiator does not have a cap, then fill the overflow up to the fill line.
Why is my car overheating after replacing the radiator?
Overheating. Just replaced radiator and thermostat, but still hasn’t fixed the problem. My car overheated the other day, and it was leaking coolant horribly. I got a new radiator, which stopped the leaking, but the car was still overheating so then we tried replacing the thermostat but it is overheating even now.
Is the water pump still hot after replacing the radiator?
I have replaced the radiator, water pump, it still run hot. I took out the thermostat and it still run hot when you drive it any distance. The temperature gauge return to normal when it is setting still and running. Help I’m at a lost to the problem. 71 people found this helpful. Did you ever find the cause of this?
Where does the coolant come from in a radiator?
Overflow Hoses For The Reservoir Tank An overflow hose runs between the radiator cap and the reservoir tank where extra coolant is stored (and added). As pressures within the cooling system change with coolant temperature, a valve in the radiator cap allows coolant to flow back into the reservoir to relieve pressure buildup which naturally occurs.

After the engine warms, you’ll see the coolant level quickly drop in the radiator/coolant tank. That means the thermostat has opened and it’s time to add more coolant to bring the level to the top of the radiator, or to the “HOT” mark on the coolant tank.
What kind of water should I use to refill my radiator?
To prevent mineral deposits on internal engine and radiator surfaces, always use distilled water—never tap water. Leave the car raised while you refill the radiator to reduce the possibility of air pockets forming in the engine.
What do you need to know about aftermarket radiators?
Aftermarket radiators are popular upgrades, but you should also pay attention to your radiator cap. Your coolant is under pressure to keep the boiling point as high as possible. That’s why you you want the highest pressure cap rating suitable for your application.
How do you change coolant in a Rad 6?
If there is any coolant left in the header tank, remove and drain, and clean out any residue before refitting. Now arm yourself with a funnel and coolant. If diluting antifreeze it should be done with distilled water or boiled kettle water – tap water contains minerals which will clog up the inside of the rad. 6.
How do you change the radiator fluid in a car?
Article SummaryX. To change your car’s radiator fluid, start by draining the old fluid from the radiator by opening the drain valve. After you’ve drained all the fluid, open the radiator cap and fill the radiator with water. Then, turn on the engine and let it run for 10 minutes to cycle out the remaining coolant.
How much coolant do I need to refill my radiator?
Some vehicles require only four or five quarts of coolant, while others may require as much as fourteen. You can find the information you need in the vehicle’s owner’s manual. Make sure to purchase the coolant before you begin the project, as you will not be able to drive the car until you refill the drained radiator.
Where does the coolant go in a radiator?
Open the radiator fill cap, usually on top of the radiator. If your vehicle has a plastic tank or reservoir for coolant, open that cap too. Consult the vehicle owner’s manual for the location of the radiator petcock, or drain, and position the container on the ground under that drain, so it’s ready to capture the escaping antifreeze.
What should I do when I replace my radiator?
With all the hoses and bolts attached, fill the new radiator with coolant. Check oil and transmission fluid levels in case any was lost during the installation. This is an excellent time to flush your coolant system and replace the old coolant with new coolant.
