Default Draining A Radiator

I have a 1992 Honda Accord Lx. I need some freon or something because the car is over heating when driven a few miles. So, I read the manual and the manual has all of these steps... loosening bolts from the radiator to drain it, this and that, this and that... then someone else told me that all I have to do is add water in the overflow container and the radiator because living in arizona doesn't warrant an antifreeze in the car. Is this true? Just sounds so weird to only put water in the car? Will I cause some type of damage to something? And if this is true, do I use regular water from the tap or bottled water? What are the steps? Thanks for any help!!

You need the rust preventives in antifreeze. If you use water only your cooling system will be full of rust and your cooling system components life will be cut short.

And the rust will obstruct the flow of water leading to overheating.

Freon is a gas that goes into the Air Conditioning System. Is the water in the radiator rusty or dirty? If it heats up after a few miles, you may have greater problems. My first guess is that the cooling system needs to be flushed.

Open the drain, (it's illegal to let radiator fluid out into the gutter), place a water hose (slow flow) in the radiator, start the engine and let it run, until clear. Shut off engine, let it drain a little water out, shut valve; add antifreeze in a 50/50 combo. Check the label when you purchase, some already are 1/2 - 1/2, Others you need to mix with water. Let us know how it goes. I have a 95 LX, not sure what a 92 looks like, but mine has a "petcock" that is easy to get to, don't have to pull the radiator. Some say you have to use HONDA rad. fluid, I just use Prestone.

If you flush the system with water then drain the radiator only as you have pure water in the engine I would not use 50/50 mix but straight coolant. If you drain the block and Radiator I would go with 50/50.

first and most important you need to find out what is causing engine to overheat..........

Or corrosion blocking the coolant channels.

i emailed the address listed and it bounced back. got another? in the meantime, my questions were... "Well, basically, I am afraid to drive this car. i just purchased it from a third part, planned on taking it to the shop, but my family and friends say that it isn't worth it since mechanics are rip-offs anyway!

Honestly I don't know what to do. How much would it cost to have a thermostat replaced, if that is the problem? How much for a new radiator? How much to remove rust form lines? How much to replace a cruise control actuator (there is a stick stuck in it)? Of course this applies to parts and labor?

And worse case scenario, what would the cost be to have an engine replaced.... (scary....)

I wanna drive :-)

Don't drive until you figure out the overheating. That will cause engine damage (~$300 for just the engine).

Check that the radiator is full of coolant by removing the radiator cap. Add a 50/50 mix of coolant/water to top it off.

Start the car, and turn on the a/c. Tell us if both fans in the engine bay turn on.

Also, look at the fins of the radiator. Are they falling apart? A new radiator will cost ~$100 and you can install it yourself. Is your car an automatic transmission or a manual?
