Small Coolant Leak and Temp Gauge Reading a Bit Low
I have noticed a very faint antifreeze smell coming from the grille of my 2006 Hemi Ram 1500 for the past couple of months. My truck now has 97,300 miles on it I only notice the smell when I walk around the front of my truck (nothing in the cab) after driving a fair distance and having it up to normal operating temperature. The outside air temperature where I live is starting to go down now (close to freezing over night) and I am noticing that my temp gauge is taking longer to get to the normal operating temp (sounds normal right). But I also noticed my temp gauge now consistently sits a hair under the center line and hovers a bit lower and then higher but never touches or goes above the center line whenever I drive - even for long distances.
Also, I noticed my reservoir is at the add line. I thought it was maybe a stuck open thermostat causing the lower reading on the temp gauge- but with the smell from the grille, the temp gauge consistently running a bit low and the reservoir at the add line I think I have a leak somewhere.
Should I go somewhere and have it pressure tested? I haven't been able to locate an obvious leak on my own at this point. Even if it is a leak should the temp gauge be reading low consistently? The reservoir was at the add line but it wasn't below it. I have added some Mopar coolant to the reservoir and will see how fast I am loosing coolant.
Any input is greatly appreciated. - Thanks.
