Radiator/Heater Coil Issue on 2002 Chevrolet Blazer

I recently replaced my radiator in my 2002 Chevrolet Blazer. We have flushed several times since it has been replaced but the water is still dirty. We placed a clearer in the radiator which instructed us to run the car for 3 to 6 hours then flush out cleaner. When we ran the engine with cleaner in it we started to get funny odor coming from ac and it looks like there is smoke coming from ac vents in car. Someone said that the heater coil had a leak and the radiator corrosion caused that leak to become plugged and the cleaner we placed in radiator unclogged leak. Please advise. Do you think that this is the issue and if so how do i fix my heater coil leak?

It is very possible that your heater CORE is bad. You will smell a sweet odor of antifreeze inside your vehicle if it is leaking, and possibly feel for a wet spot on the floor boards. Need to replace heater core.

How to flush a heater core


When you flush your radiator, the heater core gets flushed as well. You will have to run the vehicle untill the heater is blowing hot air during the flush, that way its going through the thermostat. Empty the radiator as per normal and thats it.

How to flush the radiator on a chev blazer 2000 LS


If you are simply flushing the radiator, fill it with clean water (bottled is best) and run it through a few times. There is also "radiator flush" products that help break up build up in the radiator, that you can use; purchase at auto parts dealer near you - also, it's best to flush the block as well. You local auto parts dealer will have a tool (fairly cheap) that will allow you flush the entire system, as well as specific instructions.
Please let me know if you need further assistance.

1995 TAHOE BLOWS HOT AIR OUT THE VENTS DURING ACCELERATION


Did you mean the only time it blows hot air is under acceleration?

First thing check the coolant level in the radiator. If coolant is low the first hing to stop working is the heat.

If the coolant level is fine but the coolant is muddy I woulds suspect a plugged heater core. You can try back flushing it by removing both heater hoses (engine cold) and then use a garden hose to flush clean water through the heater core. Do this on both pipes going into the heater core. Keep flushing until the water runs clear. Re attache the the hoses, remove the radiator cap, start the engine, let the engine come up to temp and top off the radiator with straight coolant (to comp for the water in the heater core). You may have to repeat this process several times over several days but you should be able to get it cleared enough to get sufficient heat without having to replace it.

Bublling in the thermostat housing and very hot upper radiator hose


I recommend flushing the radiator thoroughly if not done recently. there seems to be some sort of blockage in the radiator at this time. if you get lots of metal fragments that are flushed out during this flush, i will then recommend a rebuild on the radiator or replacement of the radiator. make sure the cooling fans are cycling on time as well.

How do i drain the radiator and flush out on a 1999 chevy blazer?


open the drain valve on the bottom inside of the radiator, run the engine with the garden hose in the radiator cap, have the heater switched on high temp.  After the water comes out clean, turn off engine and let all water drain out.  Replace with 50/50 mix if distilled water and antifreeze.  Collect old antifreeze as it is very toxic and poisonous.

96 Blazer Overheating


Yes the issue is most likely an air block, jack the front of the truck up as far as you can, fill the recovery bottle and run the engine for about 10 min, then shut down and run cold water over the radiator, this should purge the air, recheck the recovery tank and refill as ness.
