Your motorcar's radiator has the important job of regulating the temperature of your engine. It does this past cycling coolant through coolant lines that run along the engine and back into the radiator to dissipate the heat. This coolant can deteriorate over time, resulting in a reduced power to transfer and dissipate that heat. Deteriorated coolant can upshot in your vehicle overheating, which tin crusade significant damage to the engine. Forbid this from occurring past flushing your coolant at the prescribed intervals for your vehicle. Some vehicles recommend a change in coolant every 30,000 miles, while others may be up to 60,000. Await in your vehicle's possessor's manual to observe out what is advisable for your machine or truck.

1. 1

   Look upwardly your car's coolant capacity. Coolant capacity specifications vary significantly from engine to engine, so it'southward important that you look up the amount and type of coolant you will need to fill up your car with alee of time. Some vehicles require just four or five quarts of coolant, while others may require equally much as fourteen. You can discover the data y'all need in the vehicle's owner's transmission.^[1]

   • Make sure to purchase the coolant before you begin the project, as y'all will not exist able to drive the car until you refill the tuckered radiator.
   • You tin can inquire the clerks at your local auto parts store to wait up the chapters and type of coolant you need if you do not have the owner'south manual.

2. 2

   Park the car on level ground. The draining of your radiator fluid volition likely require jacking the car upwardly, so it'due south imperative that you find a level surface to park the car on before y'all go started. Attempt to utilize concrete or blacktop, equally gravel or dirt driveways may not provide adequate back up for the jack or jack stands once the car is lifted off of its wheels.^[2]

   • This project can be completed inside a garage if you have one available to you.
   • Never jack a machine upwardly on grass, as jacks and jack stands can sink while you're under the vehicle.

3. 3

   Wait for the car to cool sufficiently. Many cars operate at well over 200 degrees Fahrenheit and the heat tin compound under the hood. Your radiator is designed to dissipate that rut by pumping coolant throughout the engine and into the radiator, where wind and the fan can cool it. Considering of this, the fluid inside your radiator is extremely hot. This rut can pressurize the fluid in the radiator, causing it to miscarry extremely hot steam or coolant that tin burn yous.^[3]

   • Look until the radiator is cool enough to bear on before opening any caps or valves.
   • Depending on how long ago the auto was running, you may need to wait a few hours earlier it'south absurd enough.

4. 4

   Disconnect the battery. While you will non exist working on the electrical system of the car, disconnecting the battery is an important first step to any automotive maintenance or repair project. By disconnecting the bombardment, you ensure that the car cannot be started while yous're replacing the coolant.^[4]

   • Disconnect the battery by loosening the bolt on the negative last of the bombardment and removing the cablevision from the terminal.
   • Make certain the hood is propped up safely, either by hydraulic pistons or a sturdy hood prop.

5. five

   Jack the car up if necessary. Depending on the vehicle, you may have plenty room to slide a bucket beneath the radiator to catch the draining coolant, but if there isn't sufficient space, you volition demand to jack the car up to a meridian that permits it. Use jack stands to support the car later you have lifted it upwards. Do not exit the vehicle's weight supported past the jack itself as yous piece of work.^[5]

   • Make sure to jack the machine upwards from appropriate jack points to ensure you do non harm the frame or body of the vehicle.
   • Once you have the vehicle lifted up, apply jack stands to have the weight off of the jack and support the vehicle.
   • Y'all tin can as well utilize wheel ramps to lift the car, if you lot have them.

   Locate the drain valve on the radiator. Your radiator is located at the forepart of the engine bay, just behind the grill of the motorcar. There volition likely be one or two fans mounted on the front end facing side of the radiator, with plastic or metal end tanks on either side of the aluminum torso. The drain valve on your radiator is usually located on the commuter's side, near the bottom, on one of the end tanks.^[six]

   • Depending on the make and model of the vehicle, there may exist a plug in the drain valve called a "drain cock."
   • If you lot have difficulty locating the drain valve or cock, bank check in your owner's transmission.

2. ii

   Place a bucket below the radiator and open the valve. Brand sure you lot take a bucket that is large enough to hold all of the fluid that volition be tuckered from the radiator, and place it beneath the drain valve. Open the drain valve or remove the drain cock and allow the coolant to drain into the saucepan.^[seven]

   • Exist careful, even if the radiator is only warm to the touch, the coolant pouring out may still be quite hot.
   • Ensure you practise not allow the coolant to drain onto the ground or into a drain. Coolant must be disposed of properly in order to protect the environment and attach to the police force.

3. 3

   Close the drain valve and open the radiator pressure cap. One time the radiator is drained, close the valve or replace the bleed cock. Then open the radiator cap or the radiator pressure cap (depending on the vehicle). Y'all can locate the cap by checking in the owner'south transmission, or just follow the pipe that leads from the radiator to the engine. If at that place is a cap forth the line, apply that, or it may lead to a coolant reservoir with a cap on summit. Once you locate the appropriate cap, open information technology and expect inside; the level of fluid should be quite depression after draining the radiator.^[eight]

   • Make sure to shut the bleed valve tightly then fluid will not leak out when you pour more in.
   • The coolant pressure cap will oft be marked with warnings similar, "Do non open when engine is hot."

4. four

   Replace the radiator cap if necessary. If yous tin hear coolant boiling despite the car's temperature judge indicating a normal temperature or if you notice bubbling coolant leaking from below the radiator cap, you will likely need to supersede it. Doing and then volition require the buy of the appropriate radiator cap from your local automobile parts store. Make certain to provide them with the brand, model and year of your vehicle as well as the engine size and then yous can exist sure you receive the right cap.^[9]

   • To install a new radiator cap, simply screw the replacement cap on in place of the old cap one time y'all've removed it.
   • A faulty radiator cap can inhibit your vehicle's ability to regulate its operating temperature, resulting in overheating and impairment.

5. 5

   Fill the radiator with water. Apply a jug to cascade h2o into the opening for the radiator pressure cap or into the coolant reservoir. Once filled, close the cap and start the engine. Turn the heat on to total inside the cabin of the vehicle and allow it to run for most ten minutes, this volition cycle the h2o through the coolant arrangement to assist you get the last of the old coolant drained.^[10]

   • Keep an eye on the temperature gauge of your vehicle while it'southward running. If the paw approaches the blood-red portion of the gauge, shut the machine off immediately. Do non allow it to reach the red, equally that indicates overheating.
   • If your vehicle has an engine temperature alarm light instead of a guess, shut the vehicle off immediately if the calorie-free turns on.

6. 6

   Pour the drained coolant into sealable containers. You volition demand to transport the drained coolant to an authorized coolant disposal location. Many motorcar part stores and county recycling centers/waste material disposal centers will allow you to drop off used coolant complimentary of charge, but depending on your location yous may need to pay for disposal service. Pour the bucket you used to drain the coolant into old jugs or something else that tin can be sealed to avoid spilling it along the fashion.^[11]

   • Old coolant jugs work well to store used coolant.
   • Practice not pour the used coolant into one-time oil containers, as mixing the two fluids may prevent some locations from taking the waste coolant.

1. ane

   Locate the thermostat while the coolant arrangement is empty. If your vehicle has been overheating or failing to reach appropriate operating temperature, information technology may be because you need to supervene upon the thermostat. While the thermostat may be located in unlike places depending on the brand and model of your vehicle, it can unremarkably be found where the top most radiator hose meets the engine.^[12]

   • You tin can search for the location of your specific vehicle'southward thermostat online or inquire the clerk at your machine parts store to help by pointing out where it should be.
   • Some vehicles come up with maintenance booklets that go along with the possessor's manual. The location of the thermostat should be listed in your maintenance booklet.

Some hose clamps require the employ of a flat or phillips caput screwdriver to loosen, while others need to exist squeezed with pliers. Determine the right mode to loosen the hose clench, and so practise so and remove the hose from the metal nozzle.^[13]

   • Make sure there is a bucket under the hose to take hold of any remaining coolant that may drain out of the hose when you disconnect it.
   • Leave the radiator line continued on the radiator end.

3. 3

   Unbolt the thermostat housing and remove it. The nozzle the hose used to be connected to should have two bolts (but maybe every bit many as four) securing it to the engine. Using a paw or socket wrench, remove these bolts and attempt to remove the housing (nozzle). If it doesn't come off hands, do not use a tool to pry against information technology, as you tin impairment the parts and go far impossible to re-seal the coolant system.^[14]

   • If it won't budge, tap on information technology with a slice of wood or rubber mallet until the condom gasket belongings it in place gives mode.
   • Remove the housing (nozzle) and set it aside.

4. 4

   Scrape off the quondam gasket fabric. The thermostat housing is sealed using a gasket that volition take to be replaced. Before the new gasket can be put in identify, the former damaged gasket must be scraped off both the housing and where it mounts to the engine. You tin use a scraper or razor blade to scrape off the remaining gasket material.^[15]

   • All of the textile must be removed in guild for the new gasket to seal properly.
   • Be very careful not to damage the housing. The housing must sit securely on the engine in club to ensure it seals.

5. 5

   Replace the thermostat and install the new gasket. To remove the thermostat, simply lift it out of the at present open thermostat housing. Place the new thermostat in the housing in the exact aforementioned way y'all found the former one. Once the new thermostat is in the housing, identify the new gasket on the housing taking care to align the holes for the bolts.^[16]

   • You can buy the appropriate gasket at your local auto parts store.
   • Make sure to provide your vehicle's make, model, year and engine size when purchasing the gasket to ensure you lot receive the correct i.

6. 6

1. 1

   Allow the vehicle to cool again. Shut the vehicle off and allow it to absurd once again before attempting to progress farther. Although yous only let it run for 10 minutes or then, it may accept quite a bit longer than that for it to cool enough for y'all to brainstorm working. If the automobile's temperature gauge was beginning to ascent toward the red, it will likely take fifty-fifty longer.^[xviii]

   • Look until the radiator is over again cool enough to touch earlier moving forward.
   • If the vehicle was approaching overheating, you may demand to wait an hour or longer.

2. 2

   Drain the water from the radiator. Follow the same steps y'all used to drain the one-time coolant from the radiator to bleed the water y'all added. This water will affluent out the remaining old coolant as you bleed it, leaving your coolant system ready for you to make full information technology with a new coolant mixture.^[19]

   • Y'all will need to dispose of this waste h2o in the same way equally the coolant, so y'all should transfer it into sealable containers.
   • Make certain to securely close the drain valve later draining the water before calculation whatever coolant to the vehicle.

3. 3

   Pour in the new coolant. Refer to your vehicle's owner's transmission to ensure you fill the vehicle with the correct coolant. Almost vehicles require a 50/50 mixture of coolant and h2o, so you can either mix it yourself or purchase pre-mixed coolant and water from your local retailer. Pour the coolant into the same open cap you lot previously used to fill the radiator with water. Some systems require you to pour the fluid in slowly, as it gradually displaces the fluid out of the reservoir and into the coolant lines, so be patient to avoid overflowing.^[20]

   • Make sure to cascade in the amount of coolant/water mixture your owner's transmission indicates is correct for your vehicle'south engine.
   • Cheque beneath the car for whatsoever leaks, particularly near the drain valve. If the bleed valve is leaking, tighten information technology to stop the leak, equally it will get worse nether pressure. If you spot leaks elsewhere, you will likely need to take your vehicle in for professional repairs.
   • When filled, the coolant/water mix should reach the "max" line on the reservoir if your vehicle has one.

4. four

   Close the cap and starting time the engine again. Run the engine for another x minutes with the heater in the cabin of the vehicle on high. Lookout man the temperature gauge equally the engine cycles the water/coolant mixture throughout the coolant organization. The gauge is probable to go up a bit earlier returning to normal, which should be indicated in blue or every bit the "center" of the guess.^[21]

   • If the temperature begins to climb toward overheating, plough off the vehicle and bank check the coolant levels to make certain it is filled.
   • After about ten minutes, shut the vehicle off. If the temperature read normal, the coolant change is consummate.
   • Lower the vehicle off of the jack stands and clean upward the area, paying special attention not to spill any waste coolant or water.

5. 5

   Check the fluid levels again subsequently a few days. After a few days of regular driving, check the coolant levels over again. The fluid levels may have lowered as the coolant/water mixture filled all of the coolant lines and the radiator, and then add fluids if y'all find the level is low in the coolant reservoir. At that place are usually lines that signal minimum and maximum coolant levels. Fill up the reservoir until it reaches the "max" line if it has fallen below it.^[22]

   • If the coolant levels are seriously low, you likely have a leak and should bring your vehicle to a professional service location to exist looked at.
   • If you accidentally overfill the reservoir, you tin can drain some fluid in the same mode every bit y'all have before, but exist very conscientious, as it tin can be difficult to stop the radiator from draining one time you open the valve.
