coolant top-up ?
#31
correct...i took the reading on a dead cold engine, filled a 50/50 mixture when i returned from an extended trip I waited until the engine was warm and while it was at max, there was still significant room to add more (which I did not do).

Well I can only offer some advise related to some of our aircraft engines. Some of them are liquid cooled and like using anti-freeze that has a bit of water soluable oil in there. That helps to lubricate seals around the moving parts of the water pump and generally prevents corrosion.
Finding suitable anti-freeze is easy: If it says "recommended by GM" or something to that effect on the bottle it is OK. As final check we put a drop between index finger and thumb, then rub it. If it contains oil - it's obvious at that point.
This dates back to times where certain GM products had pretty serious corrosion issues around their water cooled engines - I had one of those...
I'm pretty sure a product like that should be just fine...

Thanks for the information on anti-freeze. Anti-freeze with lubricate or oil is probably a good idea. I will read the labels for lubricates and recommendations on the various brands before selecting one to buy.
Thanks again.

Talked to a Porsche tech about this as my coolant level was at minimum. Was worried and curious at the same time as none of my gauges went into alert mode and the temp gauge was normal. He said that both oil and coolant should be checked when the engine is warm. Checking level when the engine is cold could give you a misreading. I checked when engine was cold and coolant was at min. Will drive the car and warm up the engine and check again at that time as see if there is a difference. I think the tech may be right as, if the coolant is actually at min, the temp gauge would have shot up and I would have received some visual warnings . . .
