SOURCE: radiator flush

The drain plug should be located on the drivers side on bottom of radiator. Should be a flat tab that you can use to unscrew it. Or the faster/messier way of doing it, is to pull of lower radiator hose. Alot faster but alot harder to catch coolant to reuse.

I generally have stopped even looking for the drain...half of them don't work right even when you do find them. Far easier and faster is to remove the lower hose. If you have a closed system with no cap on the radiator then fill through the reservoir, otherwise fill through the radiator and add to bottle after you are finished. Run the heat on high while filling and wait for thermostat to open and level to drop before final fill.

SOURCE: Where is the radiator drain valve located on the

I First, you must remove the black air deflctor that runs underneath the radiator across the car. Maybe about 8 bolts. Even then I couldn't find the drain plug at first. It is on the driver's side. Beneath the radiator there is a heavy metal Mounting bracket. Almost looks like a crossmember. About an inch in from the left (driver's) side bottom of the bracket there is a large round hole with a rubber grommet. In the center of this hole it the outlet of the drain. If you reach directly above it on the back side of the radiator, i.e. come around back on the bracket and looking forward, you will find the drain ****. It is black plastic and has 2 ****, not a full petcock handle. It is still hard to see, even after removing the air deflector. The air deflector is the one people knock off by running too far forward when parking. I hope this helps .Remember the 2 or 3 vents at top of radiator hoses when refilling the system.
The radiator does have a hard to see drain plug on the left drivers' side. There are 5 10MM screws holding the air deflector on. The block has removable plugs, one 14MM hex next to the oil filter and one in about the same location on the other side of the block toward the firewall under the exhaust manifold.

Can't find the radiator drain valve to flush the radiator

If you need to flush just the radiator you're going to need to pull the lower hose off of it. Hope I was able to help....

How do I flush the cooling system in a 2000 hyundai elantra?


There are several methods for flushing the cooling system on ALL engine cooling systems. Time honored is drain the radiator (drain ****). Fill with fresh water and run engine to operating temperature until cooling fans turn on. Drain cooling system again. Refill with 50-50 coolant. Another method is purchasing a "T" vlave (coolant flush/service kit) from Autozone, PepBoys, NAPA, O'Reilys, CarQuest, etc.). This "T" valve is installed in one of the heater hoses & attached to a garden hose. Remove the radiator cap & turn on the water supply to the garden hose. Let water run until flush water is 'clear'. Remove garden hose from T valve & refill radiator with pure coolant until the T valve drainage turns green/orange. Install T valve cap... DONE!

Cant find cooling system drain **** need to flush radiator


Welcome to the club! The drain is a plastic plug in the radiator tank. Yours is most likely located on the driver's side radiator tank at the bottom. (I don't even bother looking for the things any more - too time-consuming) It is almost impossible to access and usually breaks if you DO manage to get it opened. the easiest way to drain the cooling system is to take the lower radiator hose loose. You will need pliers that are made for squeezing the hose clamps to accomplish this. You can get it done by other methods, but there will be a lot of cussing and hair-pulling going on.

How to perform radiator flush to a malibu 2003


You'll need something to catch the old antifreeze in as its a federal law not to allow coolant to go into storm drains etc. Open the drain petcock or butterfly valve on the lower corner of your radiator (It's better to do this when vehicle is cool to avoid getting burned) and NEVER open a radiator cap when the vehicle is hot. After coolant is drained if it looks like it may have thick residue or rust in it I'd recomend adding a bottle of prestone cooling system flush (follow directions on the bottle) if not put your water hose in the radiator neck opening and turn the water on halfway. Your vehicle will need to heat up to operating temp for the thermostat to open so the water will then in turn go through and flush the rest of the system out. Allow vehicle to run with water on until all you see is clear water coming from drain spout. Turn off water, wait 1 minute and turn off vehicle as this will circulate extra water from system, allow to drain completely then close drain I'd recommend using a long life coolant like dexcool (the orange antifreeze) which is good for up to 5 years as opposed to the green etylene glycol which should be replaced between 1-2 years. For added protection you can add a bottle of water wetter additive if vehicle has had a history of running at a hotter temp than normal as well. You can get the dexcool in a premixed 50/50 mixture to take the guess work out of it. Remember as well when refilling once the vehicle has cooled you'll need to add a gallon and wait for thermostat to open back up so you can fill the rest of the system as well. drain and flush reservoir coolant tank as well. Check the following morning after you've filled it to ensure it's full. Rinse of any coolant you've spilled while refilling or it will smell like that for a month.

2000 Chevrolet Impala Radiator flush Where is the valve to flush it out


On the bottom of the radiator is a valve to drain the radiator. Now if your are trying to do a flush you will have to get a kit and put a flush T in one of your heater lines. Also there is a plug on the engine block just above the oil pan that will drain the water from the block.
