Re: [Chrysler300] Temp sending unit

Neal, I have never had a temp sensor fail on any of my vehicles so 
accessability has never been an issue for me. I've replaced countless 
water-pumps and thermostats over the years and there really isn't an easy 
way to move those to a more convenient place either. No matter what, 
something will always be in the way.

To entertain your question though, you could move the sensor to another area 
but it would then give you a different type of reading. The temperature is 
monitored at the water-neck (thermostat housing)where the water is exiting 
the engine and it is at it's hottest but it is also away from the heat 
source which is important for an accurate water temperature reading. If you 
took a reading from the water jackets around the cylinders you would find 
higher temperatures because of the block temperature. Conversely, if you 
took a reading from the radiator you would find lower temps.

The other problem is that of plumbing......you would need to find a deep 
well to tap into to install a temp sensor. Manifold temperature and block 
temperature can also be monitored separately from other areas but that is 
mainly done on marine engines. I know our cars seem like boats sometimes but 
I don't think you would ever really need to do that.

Well, that's my 2 cents worth! Have a great day 300 fans. Ryan
