There are 2 hoses going to your radiator, one near the top and one near the bottom. With the engine cool, remove the radiator cap and then disconnect the lower hose from the radiator (BE SURE to have a catch can to catch all of the fluid!!!!, a few sips of this stuff will kill most cats/dogs). Once all of the fluid has drained out, reconnect the hose and fill the system with water and a radiator flush/cleaner (autoparts store). Drain it once again and refill the system with the correct mixture (usually 50/50 water and antifreeze). Or you can buy the pre-mixed kind at the store.

Good luck!

Just got a 96 Corolla and over heated. Noticed brown water coming out from under it. And when opened the radiator cap. Found brown sludge in it. Don't knw what to do

Sounds and looks like the radiator is corroded internally. My guess is that it has been leaking for a while and re-filled with water only and no anti-freeze to help keep it clean. Pull the bottom hose off the radiator and try to flush it out with a hose and see what you get.

How can i flush my clouged radiator on a 2003 kia sedona

flushing blocked radiator cores is not successful regardless of what cleaning agent is used --simple reason , if the water cannot flow through the cores ,it cannot flush out the blockage
Best answer for a fix is to replace with a new radiator and use the correct anti freeze-anti boil additive in the correct ratio at all times

Gas system freezing up, runs fine after thawing it out by running water over it. first time was low water in radiator but now doing it still with radiator full. any suggestions on the cause

It sounds like your asking about 2 different issues.
1. If you are talking about your gas lines freezing, then you should add a bottle of fuel treatment to your gas tank, next time you get gas. If you can-add the treatment and then FILL your tank.

2. If you are talking about your radiator and fluid, you may have too much water in the system. I would recommend a flush and fill service at your favorite mechanic. Most vehicles require a certain "color" of anti freeze, and we think we can purchase a bottle and go for it. Truth is, if you add the wrong kind you can damage your vehilce. Also, some people still add water to the radiator and that's usually not a good idea, for cold or hot temperature days. Why don't you list the year and make of your vehicle, and I could look up the exact anti freeze you need.

PS. a radiator flush and fill should be done by a mechanic, or someone familiar with that service. Remember radiator fluid is toxic and a small amount can kill animals and make a human very ill. Must be drained and disposed of properly. Good Luck!

How do i flush and replace radiator with anti-freeze ?

Drain the old antifreeze. Add straight water and a chemical flushing agent from a parts store, and follow the instructions for using the flush. Then drain again, and replace the radiator and use a 50-50 mix of antifreeze and water (distilled water, preferably-it is cheap) to fill up the cooling system. Leave the radiator cap loose, and start the engine and let it warm up to operating temperature-the upper hose will be hot after the thermostat is opened, and the coolant level will drop some and need topping up.

It's a good idea to also change the thermostat while you are changing the radiator. If you are not replacing the radiator itself, but a lot of brown rust drains out, then take the radiator off and turn it upside down and flush out good with a water hose.

Why is my coolant brown

The brown is rust. They did a poor job of flushing. It needs to be flushed with a good acid cleaner. If there are no leaks and it is cooling ok, it will not hurt to run with the brown anti-freeze.

Should i drain the cooling system on my 2001 mercury sable

Every 5 years,you really should,if you put more than 10,000 miles a yeasr on it.
Check the coolant for freeze protection every year and every time you add anti-freeze or water after you've run it for an hour or more(to let it mix thoroughly into the expansion tank).
If the coolant has been in there and has a dirty look, even if it tests good, you should do a flush.
Your heater has a bypass hose above the hoses that connect to the heater core. So just take a pair of clampin end vice grips and clamp off the hose before it enters the heater core(this is if you have a great heater and KNOW the heater core doesn't need flushed).The block on your car has a drain plug(allen head,I believe)on each side of the block down low towards the front.You can remove these to do a great flush or you can just keep flushing water hose water thru the radiator. The sequence is this...........
(1) Drain all you can out of the radiator(there''s a big plastic cover under the car you need to remove to get to it on the driver's side radiator).
(2)You can remove the engine block drain plugs or not,IF you really flush it well.
When you are satisfied you have most anti-freeze replaced with water, you start the car with the proper level of water in the expansion tank,and add your flushing agent.Of course follow its directions, but after running the car for a few minutes, be aware you may need to add more water as the thermostat opens.
(3)After draining out the dirty water,let the engine cool for at least an hour,then fill it with HOT water to prevent any cracking of block or heads.This also you drain out and let the engine cool all the way down.
(4)NOW you're ready to fill with full-strength anti-freeze(Prestone or equal quality)but don't use the 50/50 strength.Becausde your engine has water in it, you will blend automatically.
(2) Two gallons of antifreeze will do nicely to give you a 60 anti-freeze to 40 water ratio or thereabouts,and that will test to greater than 40 below zero F. don-ohio

Flushing antifreeze on a 2006 kia sorento

This procedure makes a bit of a mess and requires catch pans but it is the best way to flush a coolant system without cutting any hoses or adding a flush kit.

If your radiator does not have a drain plug is to remove the LARGE lower radiator hose and drain the anit-freeze. (Even if it does have a drain plug the steps below are the best way) You then plug the lower radiator hose connection on the radiator and have a 2nd person add water to the radiator with a hose. They will need to place a rag over the fill port for the radiator and flush the block until you get clear water from the lower drain hose. Once you get clear water drain off the fresh water by unblocking the lower radiator fitting and flush the radiator. Once you get cleanwater from the radiator connection, reconnect your lower radiator hose. (Tighten the clamp!) Then add your anti-freeze. Remember there will still be a some water in the block so do not be afraid to keep your anit-freeze / water ratio a tad higher because the left over water in the block will dilute it slightly.

Thanks for choosing FixYa,

What is the correct way to fill the radiator of a chevrolet venture The low coolant light came on then started flashing but the radiator is full of water but has no anti freeze is this the problem

Hi there!
First.- with the engine off and cool, put a flush and drain radiator cleaner run the engine for 10 minutes, turn it off, let it cool down.
Once the engine is not too hot, open the lowest hose of radiator while you put water in the main mouth of radiator.
Once you see the water flushing clear, put the hose back and then fill it with special GM antifreeze, (the one is orange color) put all gallon into it and the rest of water, LOOK FOR THE ONE YOU CAN ADD WATER, THAT'S THE BEST FOR YOUR VAN... Good Luck!

Its over heating and ive changed the water pump clutch fan and themostat.

You may have a blown head gasket. They can leak outside the motor, inside the cylinders (causues white smoke), or into the block causing water in the oil (light brown color and or bubbles on the dipstick) or oil in the radiator. Hopefully you have none of those, so the next step is a radiator flush as you probably have something clogging up the radiator or thermostat. You have to drain the radiator and fill with clean water. Pull out the thermostat and leave it out for the flush. There are radiator flush products that I suggest highly. Run the truck to operating temp (about 20 min) with the heat on and dump the system by removing the bottom hose hose from the radiator, after the truck cools off. With the hose still off dump water through the radiator to clean it out fully. fill with water and let it run once again to clean the block, then reinstall new thermostat and anti-freeze. This should clean out any rust and stop leak that is causing your problems.
