Hello, About 3 weeks ago I had all of my cooling hoses replaced at the Volvo shop. Well tonight as my family and I were driving home suddenly I smelled coolant. Followed by the red light with a radiator and fan symbol . I immediately pulled off the road and turned my car off. The temp gauge never went hot. I opened the hood and found the upper radiator hose off the radiator. My coolant reservoir was empty. The fan ran for like forever. Then stopped. I wonder what would cause the hose to come off like that? Any ideas?

Most likely they just didn't tighten the clamp sufficiently, normally an over pressurized coolant hose would burst before it would pop off. I would immediately go through and check all of the other hose clamps to be sure they are tight. If it had been a lower hose, you might well have suffered engine damage.

The most pressure the hose might see would likely come at red-line while accelerating.

Well it turns out that the nipple that the hose connects to on the radiator was going bad. It broke off at the shop in the morning. So, now I have a new Nissens radiator in my car.
