Hey, I have the vehicle listed above R/T and I have a constant loss off coolant, not a huge loss but it is noticeable. There is no viable leak, no white exhaust, no coolant in the oil or visa versa. I do notice a burning coolant smell when I exit the vehicle after a drive. Any help?

Leak is probably around something hot that is very slow and steaming off. Use a mirror and good lighting and look for stains and or coolant traces. I'd first focus around the exhaust manifold.

If you can pressure test it when it is cold, it may be more evident as the metal is at a contracted stage.

I suspect you have either an external leak that is evaporating which is why you smell it or it is leaking into the oil. Check the oil and make sure it is not milky. If not, then we need to pressure test the cooling system and find out how long it holds pressure. It should hold 18 PSI for a while so if it doesn't then you can start looking around the engine to find the leak.

Here is a guide on how to pressure test the system. Let's do this and report back with what you find. Thanks
