Is your Chrysler 300 leaking coolant or running hot?

The thermostat housing might be the culprit.
This VAP autoparts unit is a direct replacement for the 2.7L models from 2005 to 2010.
It's made from a combination of plastic and metal, giving you durability where it counts.
It's a brand new part, not some junkyard pull, and it's been durability tested to handle the heat.

This is a performance-oriented piece, so it's built to a higher standard than some basic replacements.

It comes in a box, ready to install, and includes everything shown in the pictures.

The manufacturer part number is IC10766301L, and it crosses with a bunch of others: 902-301, 6048001, 5017183AB, 4792329, and Z63011-I.

It weighs about 2 lbs and is designed for a universal fitment, though it's specifically meant for your 300.
It even comes with a one-year warranty.

If you're dealing with overheating issues, swapping out this housing is a solid first step.

Just match the part numbers and get your ride back on the road.
