If your radiator's are feeling cold, here's when you can tackle the problem yourself and when you need a professional ...

Q I found out my ’88 Subaru needs a new radiator because it is spewing a little water, causing my motor to overheat about every seven miles. I asked my son if it could safely be put off for a while.

With a cracked, empty radiator, miles from anywhere, there's only one thing to do - crack open a battery and start a fire.
