Cooling system pressure and oil pressure

[Diddydc]

I have a 98 C280 which requires a few mechanic fixes. Does anyone know how much pressure do i need to add to the cooling system (radiator) and the oil lubricating system.

Your post doesn't make sense. Why (and how) are you adding pressure? What is the problem?

Very strange question. Here's a strange answer.
Your cooling system should be running at around 15pd/sq.in when at normal running temperature
Oil pressure should be anywhere between around 14 to 45pd/sq.in.
You can't add pressure. There's a little pressure guy in the engine doing it for you.

Really strange thread, I just want to know who puts in the 15psi into the normal operating cooling system since water won't boil to add pressure till atleast 100 C. All my MBs normally operate below that temp.

I am just the opposite. I have TOO much pressure!! I have pressure fom my wife, my creditors and life itself. Not to mention the pressure I put on myself to get-R-done in a timely fashion. My blood pressure is high. I have too much air pressure in my tires and somtimes too much in my my colon. Heck, even my pressure cooker is over pressurized!! I need to know how to relieve pressure, not add more!

Steve: "I just want to know who puts in the 15psi into the normal operating cooling""
I told you' it's the little pressure guy inside the engine
Or, pressure builds-up because of the increase in temperature of the water/coolant which expands by being heated-up. No place to exit, it builds up pressure.
But I know you know all of that
