Thanks to all who replied. I didn't do much driving lately, however, I
checked the coolant level and made a short test drive.
The coolant reservoir was almost empty, which surprised me as recently
I was changing the oil at Walmart and paid them extra for topping up
all the fluids and after that I relied on them that there should be
enough of the coolant. Anyway, it wasn't and I added some - a little
over the line on the reservoir. During the test drive I had the feeling
that the heating system was working better and the engine temperature
gauge was showing about 50%, which made me happy...
However, I got another not too good signal - infamous "Check the
engine" light went on!...
I had in the past and it was disappearing, so I hope that it will be
the same after I add some better gas (filled up two days ago with
I would appreciate any more comments. Thanks in advance.
