Now that the winter months are here and the days are cooler (at least up
here), my wife uses the heater in her Neon more frequently.
She mentioned that it takes a very long time to warm up (cabin temperature)
and that it isn't nearly as warm as it used to get.
I thought maybe the coolant level was done, so I went to check.
After topping it off (maybe a 1/2 cup), I saw that it was full of a greyish,
slimey, almost foamy liquid, not the typical bright green of coolant.
Any idea on this? Is oil getting in?
We had the notorious head gasket seals fixed about 3 years ago, and it's not
leaving a puddle on the driveway, nor is it losing a significant amount
between "dipstick checks"
