How do I flush the radiator?

flushing tee cap....a flushing tee is added during a service by most cooling system technicians. to make the heater hose accessible. inspect the hoses that go to your " firewall" or engine compartment the event someones added it: it can be found there. if not, you may find one at the part store. determine the hose diameter so you can select the correct part. i recommend installing a metallic "mender" instead of leaving it in there. the day it decides to have a sticky thermostat, that kind of plastic can cause a large leak and you would lose all your treated coolant.

No heat in car..thermostat new,flushed system,flushed heater core..still no heat

Feel the heater hoses under the hood when the vehicle is warmed up. They should both be warm.
You may also have a valve that shuts off the coolant flow on the heater hoses. The valve may be faulty.
If both heater hoses are warm up near the firewall where they enter the vehicle then you might have a bad solenoid or switch that is not operating the blend air door that moves between the A/C evaporator and heater core.

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!

How do you flush rusty water out of the radiator on my 2004 LeSabre

Its best to replace radiator. You can purchase a flush kit from Auto Zone and back flush the system ( meaning go against the normal flow of coolant with a garden hose). But Rust usually means Radiator seen better days and you don't want this stuff causing problems around the head.

1995 Gran Am 4 cylinder. I want to back flush my cooling system using the Prestone ''Flush 'N Fill Kit. Where do I insert the Tee? I do not know which is the radiator inlet hose as this is where Prestone...

insert the tee by cutting one of the heater hoses and clamping it to the two ends that result.

determine which one is the inlet hose. It is further away from the water pump housing so that when you backflush through it, it also flushes out the heater core.

Hope this helps.

How to replace coolant system flush

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

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.
