Sorry for the stupid question
How much coolant should i have in the surge tank?
Deville 98 doesn't have a mark on the tank, on not that i know. I don't have the owners book.

Two inches below the base of the fill neck.

what would be the pressure in the cooling system when hot?
A hard upper hose, but still being able to press it with my hand, should be normal?

Take a look at the cap on the surge tank.....18 psi ??
HOT...... you should be able to get a fair thumb dent in the big upper hose.

then I got it right after changing the radiator. Now i have pressure in the system and no visible leaks. I hope no leaks at all.
