Thanks Roberto. I am still at the computer doing as much research as possible before I go.
I read your post on the 3 step radiator flush and will do that. I did notice (yesterday) while working on the heater hoses ,what I think may be the electrical connection for the auxiliary pump hanging lose. It is a female two prong connector which I though may have been for an accessory which the car did not have.
That was before I knew that there even existed an auxiliary heater pump.
I also read your expose on coolant. There was a long and exhaustive conversation between you and an engineer.
I am glad I stayed long enough to get your latest information.
I think the belt was loser than what you describe. I will check
I will really leave soon and report back.
