How to drain and flush radiator - 1998 Ford Taurus

Follow these steps: http://www.wikihow.com/Flush-a-Radiator

Refill with proper coolant and regular hose water, following manufacturer or product recommendations.

The easiest way to flush, if radiator is left in the vehicle, is to have the car at normal operating temperature, open the radiator drain, and put a garden hose into the cap opening. Turn it on till as much water enters the radiator as is leaving the drain. Run the engine as you are flushing, and run it till the water runs clean out the drain. Then shut off and refill with a 50-50 mix of water and antifreeze.
If you take the radiator off, you could run the hose into the bottom hose fitting and let it drain out the top hose fitting or the radiator fill neck. A simple back flushing method that may help dislodge and flush out any particles-but the first method should work well enough if your radiator is in good shape and not clogged up with rust and scale.

drain coolant system locate heater cores hoses going through firewall you need to buy the radiator flush kit at any auto parts stores. remove heater cores hoses from one end or buy extra long heater hoses same size as heater core hoses in vechicle at auto parts store use the flush kit when you flush through one of the heater core hoses let the other hose drain in a drain pan when you use home garden hose use low water pressure dont use garden hose to the max or you will rupture heater core. your best bet let radiator shop flush whole coolant system. because heater cores hoses are in a tight spot.make sure engine off if you just going to flush out heater core only .after flushing heater core good time to replace heater core hoses.if job too hard or complicated let radiator shop flush out radiator the engine block and heater core because if radiator stopped up or engine block stopped up the gunk and rust will reenter plug up heater core.if you tight on money you can flush out your own radiator.drain out radiator using large drain pan. remove top radiator hose and remove bottom radiator hoses connect to water pump.use garden hose with flush kit part with water pressure not too high put garden hose to top radiator hose run water until clear water run out bottom radiator hose in drain pan,the flush out engine block remove thermostat.if you had another spare thermostat housing with RTV SILICONE SEALANT THAT HAS SET UP INSTALL THERMOSTAT HOUSING BACK TO ENGINE WITHOUT THERMOSTAT FLUSH OUT THE ENGINE BLOCK, WHEN DONE INSTALL NEW THERMOSTAT THEN INSTALL ORIGINAL THERMOSTAT HOUSING WITH NEW ORING WHICH YOU BUY AT DEALERSHIP.IF ALL SOUND COMPLICATED LET RADIATOR SHOP FLUSH OUT COOLANT SYSTEM.

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

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.

1.) the drain valve is a bolt type device under the radiator..

2.) different flush has different methods usually buy the flush and follow the instructions.. usually
empty radiator by loosening valve underneath
tighten back valve when drained
pour in flush and top up with water
start car and allow to run for 15 minutes (with cap off)
cut off
let cool and then drain..

add coolant .. your done..

Your car's radiator and cooling system needs to be clean to be cool. As time goes on, your car's radiator builds solid deposits that can clog the cooling system. A quick, inexpensive radiator flush can keep the system in shape. It's important to change your antifreeze seasonally. Before you start your radiator flush, make sure you have everything you need. There's nothing worse than draining your radiator only to realize that you need to drive to the auto store for something!
What you'll need to perform a radiator flush:

• Phillips head screwdriver or wrench (whichever your radiator drain requires)
• Cloth rag
• Radiator Flush solution
• Coolant
• Funnel
• Used coolant receptacle

*Be sure to let your engine cool completely before you loosen or remove the radiator cap. Hot coolant can be painful!

Things you will need:
Radiator coolant mixture (get from garage)
Radiator flush fluid (also from garage)
Distilled water (Or if your me garden hose water ;) )

Take off the radiator cap when engine is COOL. Find the drain plug located in the bottom of the radiator (normaly hand tight) and let it drain out into a catch container. Put the drain plug back in, follow the instructions on the flush container topping the radiator back up. Let engine run as directed on bottle and then carefuly undo the radiator cap using a rag as not to burn yourself. Then remove the plug again and drain out the flush fluid. Then repeat the process with the radiator fluid as instructed on the bottle.
