The lower radiator hose on my '87 Toyota Camry burst when I was driving. Luckily, my car didn't over heat too badly. I ended up replacing both the upper and lower radiator hose, and haven't had any problems with leaks. The hoses were of high quality, and I am sure I won't have to replace them anytime soon. I would highly recomend that everyone change the hoses on older vehicles before it is too late.
