New member and new Ram owner here. Bought my first diesel 2500 a couple months ago. 2017 2500 6.7. 100K miles. I absolutely love the truck. My low coolant light came on about a month ago. I added about 1/2 gallon. Now it’s getting worse. Having to add coolant about every other day. Never seen any leaks or coolant under truck. Left it running in the driveway about 30 min, no leaks, nothing under truck. Took it to the shop 2 days ago. They did a pressure check and no leaks. It held original pressure. They left it over night with operating pressure on it. No leaks, held pressure.... Where the hell is my coolant going???? Could it be a bad coolant cap??? Need some ideas as to why it’s loosing coolant. I do know it’s not a head gasket, shop changed oil and no trace of water. Help!!!!!
