My car makes a strange sound when i turn it off. I just fixed the heater hose on it that cracked the other day. And i didn't really have to loosen anything except those clamps. Now, when i turn it off it makes like... a circular rattle..

It's sort of like when you spin a coin on a counter, but louder. it only happens when i turn the car off... Andy ideas?

Always possible that you hit something while installing the heater hose. Does it sound like it could be the fan from the heater?

What is the year of the vehicle?

its a 1996. Well, i may have figured it out, the muffler had a hole in it. And then, sometime today. the Xpipe fell onto the sway bar i believe? something under there, well.. it sucks, and i hope its just the exhaust, not the transmission. but i dont think a transmisisn would go into gear and i dont think an engine would stay in one spot if the transmission falls. so. yeah.

The loose flange on the pipe may explain the rattle.

Suggested Repair

Inspect the exhaust, especially the X-pipe and any loose flange that may be contacting the sway bar, and secure or repair the damaged muffler and pipe. If the shutdown rattle continues, also check the heater fan for contact or debris.

Conversation Summary

A 1996 Ford developed a circular rattle only after shutdown, shortly after a heater-hose clamp repair. The owner later found a hole in the muffler and believed the X-pipe had dropped onto the sway bar, while hoping it was not a transmission problem. Experts noted possible contact during the hose work or a heater-fan noise, and said a loose exhaust-pipe flange could explain the rattle.
