I had my 98 deville idling in the yard and it started pooring smoke from under the hood so naturally I shut the car off and once it stopped spewing water I noticed a hairline crack in one of the coolant hoses on the driver side back of the engine. It wasn't running hot or anything and I was wondering if this is just something that happens over time or a symptom of another problem thanks for any help.

Considering it's age, I'd say it's just "something that happens over time".

If it's the heater pipes (#5 & 6) on the back of the engine (a real bitch to replace), it is a somewhat common failure. They tend to rust out, though I'm not sure why as they are not subjected to road salt.

Yea one of my metal pipes was fairly rusty and I replaced while engine out. Crappy paint and too much heat.
Hope it's just ine of the heater hoses as the pipe is a bitch in the car to replace. Some have bypassed it.

If it's #8 it could be the hose(which is silicone, get off ebay cheaper) or the quick connect BS used to connect to the engine next to the hose.
