I have a 1997 Cadillac STS that has been giving me quite some trouble recently with the cooling system. First, I had a leak in the radiator, so I have put in a brand new radiator, thermostat and hoses (I figured I would replace all those little things while Im at it)... I filled the system back up and it is now overheating, yet there is no visible leaks anywhere when I look all around the engine compartment (when the engine running or turned off) ... There IS definitely fluid going somewhere though, but it is not into the oil... I did an oil change as it was about due and there does not appear to be any coolant in the old oil. I thought maybe it was somehow leaking into the combustion chamber and getting burnned off like this, but I was told I would see a white smoke or steam from the tail pipes and I dont have this either... I am at a complete loss as to what might be going on.
Has anyone run into this before?
Thanks for any help in advance,
