Hello to all. At the outset, I want to say hello, I'm new to this forum. I come from a Polish so please be understanding in for my poor English. On the days I became the owner of the Cadillac Seville STS my 1997, it is rather rare copy on Polish roads. I have a pytanko, at this moment, I wanted to ask, among others, for the exchange of fluid in the radiator, namely the re-flooding and control the fluid state. In my autku there is no cap on the radiator so I guess that is flooded with fluid expansion tank ?, possibly can probably faster through the upper radiator hose and pour the rest of the tank? As for the liquid state at me sadly the expansion tank is black, so I do not have a preview not to pour too much. Engine oil filters for the purchase I was instructed to Petro-Canada 10W30, and an automatic transmission Castrol Transmax DexIII unless they good? It is known, brake fluid, fluid support, everything needs to be replaced. I was grateful for all the help.
