I second the pressure testing equipment. I purchased a Snap On unit some 20 years ago now and it has saved me a pile of head aches. When using it, make sure you know what pressure your cap is supposed to release and do not exceed that.
I suggest placing the tester in place of the radiator cap and warming the engine, do not add pressure yet. Then turn the engine off and monitor the pressure. See how fast it drops. I can't tell you how long, but it shouldn't loose much, its a closed system. While its off and holding, do your inspection. The larger the system the slower the drop should be (C15 15 liter vs 2 liter). A warm motor at full pressure will show its weak, hoses, radiators, freeze plugs, or worst case, cracks in the head.
I've had a crack up inside a exhaust port that only showed up at 15PSI and 210 deg water temp all on a test bench at Caterpillar. That was my needle in a hay stack. BTW this was on a loader not my Newell.
