+1 for sure! The quickest way to destroy a cooling system is just by using water and it self destructs even faster if you have aluminum components like heater cores, radiators and heads that are grounded to the vehicle (big galvanic battery).You should use antifreeze because it also prevents corrosion (rust) in the engine block and heads. If you have a heated garage then you should be okay as is but otherwise not sure what to suggest other than driving south, try to leave the car running, or pay to have it stored in a heated environment. I would not recommend trying to just drain all the water out, as you will never get it all and it just takes a small amount trapped somewhere to crack the block.
The easiest and cheapest solution would be to pull one end of the bottom radiator hose off to drain the water out, then find your coolant capacity in your owners or shop manual and refill the radiator with half that amount of antifreeze. If you have room left, top off with water. Then start the car and drive or let it idle until at operating temperature to mix the water and antifreeze.
Draining the Rad does NOT drain the block.I opened the petcock and caught the water.mighr as well play it safe.
+1 !Draining the Rad does NOT drain the block.
If it freezes it could still crack the block.
You need to pull the drain plugs on BOTH sides of the block to drain it.
They are hard to get at in the car, and are usually seized solid.
Better to add antifreeze and run the engine to mix it, like was suggested above....
That's like shorts weather! You guys are getting a mild version of what we've had for the past couple of weeks. At least we expect it every year. And, you realy do want use antifreeze.Going be be below zero here for 48 hours, getting down to maybe 12 deg. The Gal is in the garage, it she in danger? I don't want use antifreeze, maybe there is something else I can do?
Ah yes, good Old Grand Dad anti-freeze. Now that's what I'm talking about. That along with a wood burning fireplace and a DIESEL GENERATOR.That's like shorts weather! You guys are getting a mild version of what we've had for the past couple of weeks. At least we expect it every year. And, you really do want use antifreeze.
I know it's too late now but have you ever thought about dipstick heaters, freeze plug heaters or heaters you put in line with your heater hoses? Your auto parts stores probably don't know what these are and if they did wouldn't have them in stock. You can always go start it up every 3 or 4 hours.
