My 02 s10 has rad cap on the rad and overflow hose located there which runs to the bottle. If I remove the cap (cold) there is usuallly coolant right there near the tube outlet. My 07 impala has the rad filler cap over on the engine block , again with a hose there to the bottle. If I remove the cap (cold) should I expect to see coolant near the outlet to the hose? In my case I could put my finger down without touching fluid. The fluid was also quite low in the bottle. I called the dealer and they said to drop by and they would do a quick check. Just the service advisor looked at it and he added coolant, to the line I thought he said. He told me to watch for low coolant warning and temp. No problem after I drove it awhile so I thought I'd check again. Coolant was hot so I did not remove cap. Coolant was below the line on bottle. Funny though because bottle has another little molded compartment in front where the hose is located. In there the coolant looks higher than in bottle? And when I look in bottle the bottom is covered in crappy sludge. I just had the system serviced in the past year, maybe as recent as July /aug. I'll call the dealer but I was wondering whether I should expect the coolant level, cold, tobe right up to the filler cap near the outlet hose. If not , wouldn't an air gap prevent it from sucking back any overflow from the bottle as it cooled? Of course the big air gap might mean none goes to bottle either? Or maybe it's still low on coolant?
