There are kits that are inexpensive that you hook up to your rad hose using a garden hose that would be your best bet it will have instructions with it to tell you how to hook it up

SOURCE: how to flush coolant system dodge 2004 4x4 pick up truck 4.7 engi

After playing "hide and seek" with drains for years, most times finding they will not turn or are otherwise broken, I finally got smart and began just removing the lower hose from the radiator. It is far faster, most times easier to get to and does the job!! Don't do this hot or you will get an unwanted bath of hot antifreeze. Remove the fill cap after you have the hose off.

I have a blackish color in my coolant resevore. Is this due to due to demodox coolant or do i need a radiator flush done.


You mean DexCool coolant? If it's black, you need to flush the system and refill with the recommended coolant. A radiator flush only removes 1/3 of the coolant in the system. YOu want a full coolant flush.

How to Flush the Cooling System.


Normally the engine operates at 195F, unless you have replaced the thermostat with another one at 185F. If the temperature has a tendency to rise up, the reason is a partially obstructed cooling system or/and a bad thermostat.The first part of the cooling system that gives up is the heater core, because the coolant flowing channels are thin. It is the time for a coolant flush in your car. To do it right then you need time. Plan ahead for a weekend. With a cooled engine, start with the heater core hoses. Disconnect both of them, but the dirt has to go out of your car, so with a garden hose back flush it and let the dirt to get out of your cooling system. After you will get clean discharge,it is the time for coolant bottle, remove it, discharge the used coolant and clean it. The third to come is the radiator. Open the drain cook, or disconnect the lower radiator hose, and disposal used coolant properly. Now open the radiator cap and flush with water the radiator till discharge will be clear.You think that you are done? Not yet. There is half of old dirty coolant trapped in the system. Install everything, and connect all coolant system hoses, radiator, heater core and coolant bottle. Now you have to run your car with water. Fill out the cooling system with distilled water, start engine, turn on the heater high, and run till upper radiator hose get hot. That means the thermostat opens. Let the engine to cool down, open the radiator cap, and draining cook or lover radiator hose and drain everything. You can use flush detergent, if you wanted, at this stage, but flushing with detergent will add 4 more hours, because the detergent is colorless and you have to guess how many fill and drain processes to do, to get rid of it. I do not do it, but if your cooling system is very dirty you have to do it. After the last drain, fill the cooling system with concentrated antifreeze and 30% distilled water. The reason is because it is more water trapped inside the cooling system. The goal is to reach 50/50concentration. You need a coolant tester to find this. Start the engine and add coolant till radiator is full. Install the radiator cap and bleed the system. After driving you car for a day or so, let engine to cool down, open the radiator cap check the concentration of coolant with the tester, and add antifreeze or distilled water as necessary. It is a good idea to replace the thermostat while flushing the radiator. This procedure has to be done every 2 to 3 years. It is up to you to decide to use RED GM Dex-Cool or GREEN Prestone antifreeze. In all my cars I have replaced Dex-Cool with Prestone, but I flush the system every 2 years, and I never had a cooling system problem in all my cars.

Trans fluid ed in coolant bottle did flush and two week brown oily goo in bottle


Flush coolant system again. Do you have a brown sludge in the oil. Do this get Preston coolant flush, drain radiator drain coolant tank, fill radiator with water, add the Preston run vehicle for about 15 min remove lower radiator hose from radiator. This will allow all residue to be removed from engine. Replace radiator hose. Fill radiator with appropriate amount of coolant. Disconnect tank from system and let water run through tank until it is clear. Reconnect tank and you should be good. Unless you have oil and coolant mixed which means a blown head gasket or cracked block

Hello, when the last time you have had your truck coolant system serviced? The anit-freeze needs to be reomove the coolant system flushed out (cleaned) Also, maybe a sticky themrastat and it will need to be replace along with a new radaitor cap.

. Clean the radiator inside and out---flush the inside with flush cleaner especially designed for auto coolant systems.
Flush the engine block this can be done with the radiator at the same time.
Replace the thermastat
replace the radiator cap with the correct pressure cap. GB...stewbison

Luke warm heat in a 2002 expediton


Start with Flushing out your cooling system. Flush it out with Preston Radiator flush, you have your preference of ether the super flush which takes 3-6 hours or the 10 min flush which is good if you don't have the time to flush out your cooling system.

After you have flushed out your cooling system, replace your thermostat and you should be good for another cold winter driving. What happens is that after a few years of the coolant not being serviced, the coolant crystallizes and clogs up the heater core and radiator causing poor circulation. Poor circulation will cause poor heat and or overheating issues to the engine.

Before you go through all that inspect to make sure you have the right amount of coolant in your cooling system.

Good luck and thank you for using fixya

My truck only overheats when the a/c is on


Start with the simple and replace the thermostat and also replace the coolant. The Dex-cool is only good for 150,00 miles or up to 5 years and any thing longer then that, the coolant crystallizes causing a flow restriction throughout your cooling system.
There is a TSB for thew servicing of coolant that needs to be done before replacing the Dex-cool. The cooling system needs to be flushed out to get the crystal deposit out of the system if there is any.
Gm uses Preston radiator flush to clean out the radiator and heater core of any deposit that will restrict the coolant from flowing throughout the system. Once the system has been flushed out, replace the thermostat and replace the Dex-cool with a 50/50 mix of water and Dex-cool for the best result in cooling. Too much water and the coolant will boil over and too much Dex- cool will jell up causing poor circulation.
Thank you for using fixya and good luck

I put stop leak in radiator and now the car blows cold air vs hot air when running the heater. why?


The stop leak have restricted the coolant flow to your heater core. You can try flushing out the Stop leak with Preston Radiator flush or replace the heater core. Once Cooling system flushed out, replace thermostat, radiator cap and repair coolant leak. Good luck and hope this helps, and Note: Common Black kitchen Pepper does great as a radiator stop leak without leaving any residue and can be cleaned out of the system with water and not coolant flush. Two table spoon is more then enough to stop a small leak. Good luck and keep me posted friend.
