Losing coolant
Leroy, I'm looking for info to support theneed for a puke tank recovery system. I have also looked for closed systems or systems that direct you to leave the closed system full of two cubic foot of air as bluebird direct.



Here is some good reading onCavitation at the end of the page is a list of way good articles. Very informative on all cooling aspects.



I know as Don says, things cool as they are and all is well but it doesnt hurt to learn and toss some ideas at proofand criticism.

> Thanks, I thought that is what would happen. I have been reading the DD service manual, several sections regarding cooling and PM. There are two references to the pressure cap, a 7psi and a 9psi. No recommendation. To pressure test the radiator it says to run the pressure up to 15-20psi, do not exceed 20 psi and look for leaks and or leak down. My 13psi cap was on the coach when I purchased it and all has been well. I was wondering about the seals on the water cooled piston sleeves and how water pressure would affect them. With a 20 psi test procedure a 13psi cap should be OK. But now I wonder if I should change to 9psi.
