How do I flush the radiator


Removing the drain plug and just letting old coolant drain out and then refilling doesn't really flush it out. It only drains what is in the radiator and it doesn't circulate and flush what is in the engine and heater core.
Take radiator cap off, then take top radiator hose off where it comnects to the radiator..only disconnect that side of the radiator hose aim end of hose downwards and leave it there. Take a wet rag and push it into the radiator where the hose was connected..you don't want to push it in so far you have trouble removing after flushing...the wet rag is just to limit the amount of water that will come out of radiator where hose is no longer attached..crank car and coolant will start to slowly come out the vend of radiator hose aimed downward...have a hose or 4 or 5gallons of water...right after you crank the car pour the water or befilling the radiator with the hose...you want to keep the water going in the radiator as to keep it fulI...replace what is coming out of radiator hose...continue to add water until what is coming out of the radiator hose is clear water.. this way the water is circulating through the entire cooling system and engine. When water is coming out clean...turn car off remove rag from radiator and reconnecupper radiator hose..the drainplug is at the bottom of the radiator on the side of radiator that is on the drivers side of the car....remove drain plug and drain water left in radiator..replace drain plug and crank vehicle and fill radiator with coolant recommended for your vehicle... Sounds more complicated than it really is..other option take to a repair shop and have them flush with machine..usually around 100 bucks at ashop..Iif you have any questions Iwill be glad to answer..

How to drain coolant


They do clog up and will not drain. You probably found the drain. Pull the lower radiator hose. If you have access to air and can shoot it up in the hole. This might help you problem.

How do i change the radiator fluid?


Most radiators have a drain plug on the bottom tank the engine block also has a drain plug . Remove the radiator cap ,open both drains ,let all the coolant run out, if there is no radiator plug remove the lower hose , remove the heater demister hoses, with the heater control on hot flush out all the coolant from the heater radiator. with a garden hose, till the water runs clean, tighten the radiator plug or re fit the hose,put a garden hose into the radiator and flush out till the water at the block plug runs clean ,refit the heater hoses, refit the block plug, fill the radiator from the hose leave the cap off , If it has a overflow tank clean and flush it. start and run engine for 5 minutes top up radiator if needed . stop engine and drain out all water. most important that all old coolant is drained out, only buy the best coolant you can . If you make up your own use only distilled water. keep some to top up with never mix with another brand. Fill radiator with coolant top up over flow tank, run engine top up coolant as needed, refit radiator cap run for another 10 minutes check for leaks,

What is proper method for flushing the radiator and engine in a 1999 Pontiac Montana?


1: Drain coolant system
2: Purchase coolant flush, making sure you have the proper amount for your size of coolant system
3: Pour coolant flush into your radiator, filling the rest with water
4: On the coolant flush bottle it will tell you how long to run your vehicle
5: Once done running, let cool enough to open radiator cap, and drain system COMPLETELY by first draining out of pep **** on radiator, then taking one side of the hoses off the radiator and draining those
6: Put hoses back on and fill system with coolant. When the fluid gets to the top of the fill port on radiator, start vehicle and let run, allowing air to escape the system, and fill as necessary

I want to learn how to drain and flush my radiator. I need help on how to do so without making as mess


well its bound to make a little mess but you should have a drain plug on the radiator at the bottom towards the engine side on one of the 2 tanks (sides of radiator ) unscrew drain plug and let drain into a pail or pan ( 2 gallon ) after it drains remove lower radiator hose. use a garden hose and fill radiator and let it flush for a little, hook lower radiator hose back, tighten drain plug and fill with a 50/50 mix new antifreeze,

I need to flush and fill my radiator but cannot seem to find a drain at the bottom of the radiator. Only 2 small metal pipes going side by side into the bottom. Where is the plug? Also, how much 50/50...


There is no drain on the radiator, loosen lower hose to empty coolant. Metal pipes are the transmission fluid lines.
Coolant quantity for the 6 cyl is 14 qts, and 15.3 qts for the V8. If you have the extended wheelbase model, the quantity is 15.2 qts and 18 qts respectively.

How to change/flush coolant on a 2003 jetta


Slap on those vinyl gloves because the ethylene glycol in antifreeze can cause skin damage - however we recommend this because the antifreeze feels like engine oil.With your catch pan in place, remove the radiator drain plug and collect all old coolant. Immediately dispose of the coolant as required by environmental laws - if you are to surrender the old coolant at a waste management facility, be sure you use containers which can be properly sealed to avoid spillage, etc.To expedite the draining process, remove your radiator fill cap to allow air to enter the system.
Also be sure to remove all coolant from your radiator reservoir. We suggest you use the gravity siphon trick - just be sure not to ingest any coolant.

Watch the old coolant as it exits the system - this will give you a good idea of your vehicle's cooling system condition.If you see metal flakes, oily surface, white flakes, etc .. you can make a diagnosis of your engine's coolant system.
Essentially, if you see anything but coolant and some very minor debris, it can indicate the early signs of cooling system failure.When all coolant has been drained from the radiator, replace the radiator drain plug and then fill the system with plain tap water to dilute remaining antifreeze in the engine block.
With the cooling system refilled with tap water, replace the radiator fill cap and run the engine allowing it to reach operating temperature.When the engine's cooling fan turns on, it is an indication that the vehicle's thermostat has opened, allowing the freshly added water to circulate through the engine thus diluting the remaining coolant. Allow the engine to run for a few minutes before shutting it off.
At this point, you can either wait until the engine cools off, or take fate in your own hands and continue the flushing process.Repeat the draining process being sure to once again collect and dispose of all waste coolant.
At this point, if you have opted to purchase a radiator flush kit, you should refill the cooling system with tap water and add the caustic fluid as directed.
Run the engine for as long as the radiator flush kit calls for (usually less than 10 minutes).

Once again, drain the cooling system, collecting all waste fluid. This is the last time you will be required to collect engine coolant during this process.Now that the cooling system is empty, replace the radiator drain plug and refill the cooling system with distilled water only. The reason that you should only use distilled water at this point is to avoid mineral deposits which will deteriorate your cooling system over time.
Once the cooling system has been completely filled, start the engine to allow the water to circulate. Once again remove the radiator drain plug. As the engine runs, pour fresh distilled water into the radiator fill hole at the same rate that it exits the system.Continue this process until the water being drained from the radiator appears to be clear and free of debris. Once you are satisfied with the drain water's appearance, stop the engine and allow all remaining water to drain out.Replace the radiator drain plug and prepare to mix your distilled water and coolant.
Be sure to mix your coolant to the ratio recommended by your manufacturer. In most cases, the ratio is 50% distilled water and 50% coolant.
As a tip, mix the coolant and water in a third container being sure to observe the proper ratio.As you mix your water and coolant, use your hydrometer to measure the specific gravity - this will give you a good idea of whether or not you are mixing the coolant and water properly.
Once you have mixed enough coolant and water to fill your engine's coolant system entirely, grab a funnel and place it in the radiator fill hole.Fill your radiator at a rate of no more than:
{ 1 L/min. \ 1.1 US qt./min. \ 0.9 Imp. qt./min. }.
Continue the filling process until the coolant reaches the bottom of the fill neck. Now fill the radiator reservoir to the full mark.
With the radiator fill cap still off, start the car and allow it to idle. As the engine runs, continue to add coolant as air escapes the engine and cooling system.As you top up the radiator, be sure to "burp" the cooling system by firmly squeezing the radiator hoses (both upper and lower). Continue to squeeze and release the hoses to help push any errant air bubbles out of the system.
Once you are unable to fill the radiator any further, replace the radiator fill cap and stop the engine - you are finished.

How to flush radiator in a 2004 Mitsubishi endeavor


Drain your existing coolant from the coolant system there should be a drain petcock on your radiator along the bottem. Once the coolant is drained add water and a radiator flush solution, availeable from most auto parts stores, refill your coolant system and run your engine usually 10 minutes or more. Check the instructions on the type of cleaning solution you buy. Afterward drain the coolant system, flush with water by filling and running it again, then drain and service with proper level of coolant. Always remember to let your engine cool between runs to safely remove your radiator cap DO NOT remove the radiator cap if engine is still hot from running.
