Chrysler 300M 3.5 Interference Engine?

Q. Hello my name is Robert nice to meet you. There seems to be an argument regarding the 1999 Chrysler 300M 3.5 liter V-6 engine. Some say it's a freewheeling engine, non-interference, and others say its interference. I want to believe its freewheeling but even I'm not sure at this point. Can you please send me some facts on whether this Chrysler 3.5 is interference or non-interference?

Chrysler 300M 3.5 Interference Engine?

The issue was raised because of the timing belt breaking and whether there would be valve damage.

Thank you,


I have been asked this before. The information I have is contradictory. According to Gates, it is a non-interference engine. According to the Chrysler manual, it is an interference engine.

I would be inclined to go with what Chrysler says because they would know better and it is always safer to assume an engine is an interference engine.
