Archie, as a side note, Toyota just explained to me na it's not"welding" daw, dapat "hinang" lang. I told them isn't that the same thing? Magkaiba daw kasi hindi daw pwede welding. Well, anyway, I didn't pursue it anymore kasi accdg to him, hindi daw ganun ka safe kasi baka bumigay in less than a year due to internal pressure?

1D4LV and KILL, it looks like we will have to replace it. I asked Toyota how much it would cost: 25K for a Corolla Lovelife OEM! YIKES. Sayang lang pala pagpa-overhaul last December.

My next questions:

1.are there any replacement brands that would be recommendable instead of OEM? or dapat OEM talaga pag radiator?
2. i was thinking of calling other shops for OEM prices to canvass better prices, but I don't know how to spot a fake vs orig.. may mga fake ba na OEM radiator?

Thanks again!
If it is a copper brass pipe, you do not "weld" or "solder it" -you braze it. The material is too thin that welding it would burn a hole right through. Solder is not a good material for something that bears a "vibrating" load such as a radiator hose.

If it is corroded, you first determine why it corroded. It takes a lot to actively corrode brass in a loop like that. You must at least have stainless steel somewhere there and a huge amount of stray currents.

I would surmise that pipe broke off because either your radiator was not properly installed, or that it was a bad replacement that was off tolerance from design. Your hose must have been pulling at the pipe and shaking it off.

Vibration testing is critical for new radiator designs coming out into production. If the hoses and the mountpoints break off, they need to re-designed.

There should be replacement aluminum radiators there if you're on a budget. The ones from Thailand and Taiwan are pretty decent.

Go with copper-brass if you plan to keep that car forever.

Coolant wise, long life coolants, in a 30-50% Coolant-Water ratio will do you well. The CASA coolants are some of the more sensible ones, but specify their long life coolants. Most aftermarket coolants tend to be geared for relatively frequent replacement.
