SOURCE: oil cooler line

There should be two tranny lines going into the radiator. That means there should be a total of 6 hoses going into the radiator.
Hope it helps.

The oil lines going to the radiator is your transmission cooler lines, you will look for a smaller radiator and its connections, usually connected using an oil filter adapter.

1999 Mazda protege has a oily leak just under the radiator what could it be

If the oil you are referring to is pink or red, then it is your transmission fluid. If this is the oil type then I would check the upper and lower tansmissions lines that are routed into your radiator. The purposem of these lines is to cool the transmission fluid. Please see the attached for additional help:

A water line to the radiator is broken at the radiator. can it be fixed?

A water line, Is it a hose or a little pipe? Is it for water or oil? Either way, a radiator shop can fix it, they can solder it back together. But I've never seen a water line to the radiator, 2 hoses, and 2 transmission cooler lines at the bottom. Once you get away from the radiator, then you have a dozen water lines running all over the place. Hope this helps.

My mazda 2002 protege is running hot when ac is on

your car temp is hot because the air-con automatic fan/cooler on the condenser is not functioning. check the electrical connections from the switch as well as from the compressor. otherwise check the thermostat. the fan should run when the aircon is switched on.
