Road Test of Stant vs. Shewman Thermostats

So tell me, what's the big deal about having a bleed hole? For the last 60 yrs. I have just filled my radiator and let the engine warm up and then top off the water and it is good to go, never a problem.

So, it's NO big deal if you never have a problem. I was probably close to the same 60 years into my own engine 'career', when I encountered MY first problem. I had a fresh build, with an air pocket that didn't allow the t-stat to open soon enough (on first start-up), and I got that fresh engine hot enough to burn the new paint. So, starting then, I put in a 1/16 hole like Henry shows, if the stat does not already have a built-in bleed. JMO
