I think you have that backwards , the heat builds the pressure . Also one thing some of you are forgetting is the new cars running higher coolant temps also run HIGHER SYSTEM pressure , I had to buy an upgrade kit for my rad pressure tester , it tests up to 30 psi now .

Higher system pressure raises the boiling point of water and helps prevent steam pockects.

Yes new cars do run hotter but lets not forget the new motors are built to much better tolerences. New cars run 200,000 miles all the time. The 60's motors were worn out at 70 or 80 K on them.

Hasn't been hot enough to make a difference but I will report back. ... FINALLY!!! THE MYSTERY IS SOLVED!!! ....HATS off to Doug for the topic and NachoRT74 for that awesome link put a stock housing on and a milodon pump and it cruzed all day long in 90+ florida heat yesterday, stop and go, everywhere!!! The 440 housing I had, you could barly get your pinky into the 90 deg turn in the lower opening. I put that 440 housing and pump on my new motor 2 1/2 years ago and could'nt get the temp down but never suspected the housing because it was brand new..........

Maybe the 4 or 5 speed overdrive lock up converters have a little something to do with it and their 2.0 final overall drive ratios.

I do not agree. I've never seen a 318 worn out at 70-80k miles, much less a /6. If they wore out it is simply because people did not take care of them

That does not mean every american engine ever built in the 50's and 60's would run for 200,000 like the newer motors do. Anybody that has spent any time working on cars will know that. Into the early 80's american car engines were worn out around 90 to 100 K. Simple fact. Lot's have changed since then. Back in the 70's and 80's they were rotted to the door handle's in 5 years. You don't see them rotted like that anymore.
