SOURCE: 1993 chevy camero- thick, rusty colored residue in radiator

The rust is probably in the engine. There are many little pockets, water ways, water jackets (around the cylinders), etc, so getting all the rust out without dunking the block and heads in a cleaning tank is about imposible. I would recommend giving it really good flush every 4 to 6 months. I would try flushing the radiator before replacing it because it is probably not rusted, even though it is full of gunk.

My heater works fine if temp outside is 15 degrees or higher but blows only cold air when colder outside.


Dianna, check to see if you do have antifreeze and it is at the proper level. if there is not enough antifreeze in the radiator or it is to low it will freeze or not circulate properly in colder weather leaving you with no heat. if your antifreeze is good it may be a sticking thermostat going bad or it could be a water pump going bad, not circulating enough. also any local auto parts store can and should check these for you if you ask them. i hope this gives you a little hope.

Hello don thanks for the good info. ive checked for any kind of external leaks,and there are none. i also checked the carpeting,and its not wet. lastly i put the defroster on,and nothing on the windsh


I'm not Don (obviously), and I am not privy to you original question, but I think it must concern a mystery coolant leak, based upon your statements here. You have done well in eliminating many possible sources of leaks. I will point out, however, that is the there is a leak from the water pump weep hole, it often goes unnoticed as it is in a very inaccessible location, it usually only leaks when the vehicle is running at at temperature, and the leak is usually small enough that the coolant will quite often evaporate on the block before it ever hit s the road surface. Since you said you flushed and filled the system for the first time 6 months ago and it is already rusty colored, I would seriously suspect the water pump since it uses the coolant as it lubricant for the shaft bearing. Just my two cents worth (for what it worth) (lol).

Coolant is a rusty milkshake consistency


if you do not see any obvious leaks under the car and you are still adding water to it, you might have a cracked head gasket which is causing coolant to go into cylinders. If this is the case, this can cause more problems.

Dipping of rusty water


yep heater core in dash leaking,sound like heater core rusted out if you used straight water.you need to have radiator and engine block flushed because rusty water is in the entire coolant system, you need flush coolant system replace thermostat add 50/50 antifreeze and water mixture never run straight water because straight water in winter weather will cause water freeze up in cylinder block and crack cylinder block you need antifreeze mixture in coolant system to keep coolant from freezing.

Your 1997 Avalon will not work the same as when it was new. Midway is normal for a 1997 car without signs of leak. If you haven't change the coolant since you acquired the car, then flushing the old with new is the best suggestion.

Totally rusted radiator ,what this eventually does to water pump ect.


If the radiator is rusty then the entire system is rusty. You need to drain and flush the cooling system, replace the thermostat, and install a fresh supply coolant. Use a 50/50 mix of antifreeze and distilled water. If the radiator is really bad you may have to replace it.

Proper method on coolant system flush


Best way is to buy a flush kit. It is an adaptor that you put in your heater hose and can hook up a garden hose to. You cut the hose and put this device permanently in the line. Remove the thermostat, don't put the new gasket in there yet just put the outlet pipe back on and bolt it down. Run the car when cold with your hose running for about 10 minutes with the radiator drain valve open on the bottom of your radiator and the cap loose, water should come out of the drain valve and the radiator cap. This will flush your engine adequately, why waste money on distilled water, save that for topping off your battery. Turn off your engine continue to allow water from your hose to flow as long as you are seeing any thing other than clear water flow until it flows clear. Turn off the hose, put the cap on the flush port you installed. the port stays under your hood and allows you to flush your engine as needed. Let the water drain through the drain valve. Put in a new thermostat, with a gasket this time. Refill with water and antifreeze as directed in your manual. You should be good to go.
