Question about Ford Escort
It sounds like you have a Head gasket leak or a cracked Head or Block. Check your Sparkplugs for color and fouling. It can be in the early stages of failure and the Sparkplugs are holding up; or the leak is putting Antifreeze into the oilpan. Check the Dipstick. Somehow engine compression is getting into the water passages. Check exhaust for sweet smell while running and excess vapor which is actually steam.
There are several ways to find this type of leak. A Radiator pressure tester will show a drop in pressure. This will verify the problem. You will be able to find an external leak with this test. If you use a Chemical Tracer, the Pressure tester will force the Tracer into the crack. The Tracer is more reliable than depending on Antifreeze color to find the leak and will show up in the oil.
By checking the Sparkplugs for telltale signs first, on the V engines you may only have to remove 1 cylinder head instead of 2. This will save you time and money. If you have no luck in identifying which side is bad, both will have to be checked by removal.
There are products which claim to seal these leaks. The Radiator pressure can range from 14 to 21 PSI. Without engine compression of 140 to 180 PSI the sealers sometimes work. But if engine compression is getting into the Radiator you will be blowing out antifreeze through the overflow pipes.
You did nothing wrong in changing the Radiator hose. You just repaired the weakess link. Now that the hose is stronger the leak moved somewhere else. Good luck on this repair. The Tracer chemicals are available at Autozone, Oreillys and several other places.
