    This has been occurring for a while; just keep forgetting to put a post up. I see no exterior signs of an antifreeze leak and the level in the reservoir is constant. Has anyone experienced this and any suggestions on what to look for it it is an antifreeze leak? Thanks in advance!

    Look around for pink crusty stains around water pump, coolant tank, rear of engine, coolant hoses.

    If level is constant, not antifreeze, may be the adblue fluid? Does it have a whiff of ammonia? If so, it's adblue and I believe it's not normal.

    I had a post on same issue. Had all kinds of tests done and nothing. They think it is coming from over-fill tank.

    I get the occasional whiff of antifreeze too and all checks out well. Complete mystery.

    Check after cooler or do a pressure test (very easy)
