There are numerous radiator flush products on the market. Most will work well if instructions are followed. if radiator only needs "routine" service, you should have no problems. If it is plugged up, generally it should be flushed by a competent radiator shop or just replaced. You can't clean a thermostat. If the stat does not work, change it. The only problem you may have is either finding the radiator drain or opening it once you find it. You can easily remove the lower hose and get the same result...just don't do it on a hot system.

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,

Suburban overheats while driving but cools while stopped. Heat works very good

the flushing of the radiator did nothing as it only cleans out the already open cores but the blocked cores are still blocked. Fit a new radiator and possibly the bottom radiator hose as it may be sucking in as well restricting the flow of coolant from a partially blocked radiator cores.

Radiator blocked

There is no way that a blocked radiator can be cleaned out . Flushing only cleans out the already open cores. Best and quickest way is to have a radiator shop replace it with a new radiator core . They will fill with the correct anti-freeze and ensure that there are no air locks in the system. Radiator guaranteed and so is the workmanship. Probably 2 hours time and you are on your way.

Replace raditor 2001 chrysler 300 M

1. Remove or disconnect the following:
  • Disconnect negative battery cable.
  • Drain cooling system.
  • Upper radiator hose .
  • Upper radiator closure panels.
  • Radiator fan assembly .
  • Radiator fan electrical connector.
2. Raise the vehicle

3. Remove or disconnect the following:
  • Lower splash shield.
  • Lower radiator hose.
  • Lower condenser mount bolts
4. Lower vehicle.
5.Remove or disconnect the following:
  • Upper radiator mounting brackets and bolts.
  • Upper condenser mounting bolts.
6. Separate condenser assembly from radiator.
7. Tilt radiator toward engine and remove radiator from vehicle.

Clean radiator fins are necessary for good heat transfer. The radiator and air conditioning fins should be cleaned when an accumulation of debris has occurred. With the engine cold, apply cold water and compressed air to the back (engine side) of the radiator to flush the radiator and/or A/C condenser of debris. The installation of the new radiator is the opposite of the removal. Please upvote if this was helpful. :)

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.

How do I replace ther radiator in a 2002 Dodge Strarus

Start by using a clean drain pan placed underneath the radiator drain plug, use a 3/8" one foot length of rubber hose on the radiator drain plug and open the drain plug with the other end of the rubber hose in the clean drain pan, this way, if your coolant is clean, you can reuse it. Next, remove the bracket on top of the radiator, remove upper and lower radiator hoses, remove transmission cooling lines from the radiator, then remove the cooling fan(s). At this time the radiator should lift straight out. Check bottom core support and make sure it's straight across. If the bottom core support is bent, this is the best time to get a big ole hammer and straighten it out. I've changed many radiators because of parking blocks, parking blocks are not forgiving on these types of cars. Good luck, Gary

Any ideas how to block a radiator in a car,might sound way out,if I were to take radiator out and connect to a basin,then use a plunger on basin with water in the rad,would this work or not enough...

that method will not work, the best way to clear the radiator is use a garden hose, take a rag and wrap it around the hose to seal it and then put the hose into the bottom radiator hose connection pipe, this will reverse flush the radiator and force the sludge out the top of the radiator,the rag seals the hose so you can build maxium pressure to back flush. having a radiator flushed by a radiator repair shop is not that expensive if you remove the radiator, I really recommend you have them clean the radiator right, an overheating engine can cause damage very fast, so a professional cleaning is worth the money.
