I have a 2009 Dodge Challenger R/T, V8, automatic, approx 146K miles.
This evening I noticed a small antifreeze leak. It’s coming from the upper right of the radiator, just above the upper radiator hose (passenger side). It’s not the hose leaking; the leak is clearly coming from around some component just above and slightly to the right of the radiator hose. Looking at various diagrams, I can’t seem to find what part this is. When the engine is running, though, there is definitely a small/slow coolant leak coming from around the component. It’s in an odd spot, so I can’t get a picture of it. Honestly, it looks to me like some kind of plug in electronic sensor or device.
Can anyone tell me what this component might be? I’m hoping it’s not part of the radiator itself…
It may not matter… but I did just recently have the transmission fluid changed, I assume through the cooling lines. But I believe those lines are on the other side of the radiator.
