No Freeze Hose

I served the circuit for one hour and filled with two liters of antifreeze. Top radiator hose collapsed just before I did. I also replaced the thermostat and radiator cap. I have a 1994 Ford F150. By the way, there is no water in oil.

must be flushed more than what you did to get all the rust out, parts store they have a radiator cleaner you can clean the system and add cleaner to clean water and perform for a day, then rinse the whole thing again, then add your 50/50 mixture of antifreeze and water.

You can rinse the radiator you everything you want, but you need a flush machine to do it correctly. Sounds like he has not been emptied since 1994. Most shops can do a cooling system parts for flushing about $ 70 and work. This will flush the cooling system is simply not the only radiator. If this does not help the replacement radiator will be needed.

Rust ....
Have you set the thermostat to the right. I've never seen a radiator hose before top collapsibility. than the bottom will do when the thermostat fails. You must also put coolant in. 50/50 does not coolant 100% means that it will cool better.

because the radiator is rusting if you need to flush the radiator and keep clean all the time than you need to buy another radiator that you

A bit of bad news, you must rinse it again if you didn't have the truck running while you do that all the old fluid coming out of the radiator and the engine.

if it is not oil deposits probably just rust or water
