Coolant Level

Hello All,

I have a coolant level question for everyone. A few months ago, I noticed the coolant level right at minimum mark on the reservoir. Didn't think much of it figuring maybe it was just cold from winter. However by March it was below the minimum mark so when I was getting my CAT swapped out (yep, been there too) I made the dealer top it off. It was right at Max when I checked after I got home. Last weekend I decided to check a few things over after a little road trip and the coolant was back near (but still above) the Min line. Seems to be well lower than what it was just a few weeks ago. To be clear, the coolant was at normal operating temperature when I checked both times just after shutting off the engine.

I am beginning to think I have a slow coolant leak somewhere. I have not had any overheating issues or warning indicators come on. The fluid is bright pink as I think it should be. I know the level doesn't stay perfectly consistent, but it seems concerning.

Since I don't have an assigned parking space at my building, I can't easily tell if there is a leak from under the car. I really don't want to go back over to the dealer (for the 7th time in 16 months) on a hunch but I also don't want to ignore it either necessarily. Should I fill it back up to the Max line and see if it goes down again? Should I get an oil analysis done? Is there some other method I could use? Or am I just being paranoid? Thanks for the input.

Sometimes the vehicle gets a small drip that drips onto a hot engine part and steams off,so you may never get to see the fluid on the floor.I would go under there with a bright flashlight after driving it,and go under after its been sitting for awhile.I would check the water pump area to start and look for wet areas.Do you smell hot coolant after you park when you go in front of the Jeep?

Make sure radiator cap is on tight and hose between radiator and overflow connected well. When cool/cold, open the radiator cap and check where the coolant level is in the neck. Should be within an inch of the top. First thing the dealer would likely try, if there is nothing obvious, is to replace the radiator cap. You can try that yourself and either fix it or save a trip.

Just drove home and smelled around once I arrived. Nothing that smells like coolant to me. Everything looks dry. I'll have to wait till tomorrow morning when it's cool to check the cap and underneath. I'll keep you posted. Thanks for the suggestions so far. Enjoy your weekend!
