My just overhauled Atomic 4 (1972?) is only reaching about 110 degrees on the test bench.
I ordered a new single action thermostat and the bypass valve, but I really don't see how that will help. The old double action t-stat tested okay, so I'll keep it as a spare.
During the overhaul I replaced the water pump with the newer more powerful version. Could that pump be over-powering the thermostat?
On the test bench my raw water is tap water at 55 degrees. Could that be the problem?
The engine is under no load on the bench, beyond driving the alternator.
Even at 3000 RPM, the head is hardly warm to the touch, and the only place too hot to touch is at the front of the exhaust manifold. I mention this as I naturally assumed my gauge or sender was bad.
I'm a rookie, so I'd love to get some cogent ideas about this problem (because I have no cogent ideas myself.)
