I have a 1979 Ford Thunderbird with a problem. I just had the water pump changed, but the radiator is empty?

I'm afraid the battery will overheat, and I don't see any water on the garage floor. We've checked the hoses, and I am contemplating adding %26quot;stop leak%26quot; to the radiator. Would that help, or cause bigger problems?

You might have had a air bubble, fill it again and run it 15 min and let it cool and then ckeck it. try this several times, if you are still loosing water and no external leaks then you might have a bad head gasket and could try water glass (sodium silicate) or block sealer. it can plug up the heater core, be sure to run it 20 min

i own a repair shop,,and i wouldn't add any stop leak to it,,id see if i could find the leak,,it may be in the radiator,,but if you add stop leak in it ,,it will stop up the heater core on it,and cause other problems to it,,id add water and check it,,it will show where it s leaking from,once you add some water in it,,and it may just be leaking while its running,,but id check it real good,,also see if you have a wet floor board,,,other wise just take your time and you will find it,,good luck i hope this help,s.
JUST FILL THE RADIATOR WITH ANTIFREEZE AND WATER , AND SEE IF IT IS LEAKING , PUT RADIATOR CAP BACK ON TIGHT LEAVE HOOD UP AND LEAVE ENGINE IDLING UNTIL IT HEARS UP , IF LEAKING YOU SHOULD BE ABLE TOO SEE IT , YOUR BATTERY WILL NOT HEAT UP , THIS HAS NOTHING AT ALL TOO DO WITH YOUR BATTERY , BUT YOU WILL BLOW YOUR ENGINE IF YOU DRIVE WITHOUT THE PROPER AMOUNT OF COOLENT IN IT ,
Get a new car. The one you have is almost 30 years old, and they don't last forever.
No water in the radiator will have absolutely zero effect on the battery. Batteries only overheat when they are overstressed or overcharged. Your problems are much bigger if you drive your vehicle with a dry radiator. A dry rad means no water flowing through your engine block. This will result in almost immediate overheating leading to very quickly to expensive things breaking internally in your engine. The first thing you should do is fill your rad with water and then run the engine to see where the leak is coming from. Since you just had the water pump replaced, I can't help but wonder if the installation wasn't done properly and that is the source of your problem. When you add the water (or anti-freeze) to the rad, start the car, but leave the radiator cap off (for older cars, without an overflow tank) or just fill up the overflow tank. As the car runs, the engine should draw water out of the rad (or o/f tank). Keep it topped up as the level changes until you are certain that the cooling system is full. You should be able to detect the leak by now. If you cannot, it is quite likely that the mechanic that replaced the water pump didn't go through this procedure and left your engine without enough coolant to properly take care of itself. Keep an eye on it for a few days to make sure everything is OK.
