On my 03 DTS, 25K miles I notice when it is pulled in the garage I can smell anitfreeze at the front of othe car for 30 minutes or so. It has done this since I got in in march with 21K miles.(anitfreeze & thermostat changed in April 22K miles) I only notice it a little when parked outside if there is no wind. It seems to be coming from under the hood, no smell at exhaust. The level is not dropping enought to notice and nothing dripping. I marked the coolant tank today while cold to look any tiny drop. If I remove the plastic engine intake cover can I see the WP incase it has a small weep? I do know it had a WP mounting plate leak repaired at about 12K, and they could see it puddling before the rpr. Is this normal, anyone else have this happening?
