Just rebuilt my 318, is a thermostat needed in a warm climate? Will the engine run cooler without the thermostat any difference? Appreciate your thoughts, thanks.
A thermostat is not optional equipment.
an orifice
And if it does not have one, drill a bleed hole in the stat. Regardless, I ALWAYS pull the heater hose connection close to the stat (not the pump) off at the heater so the system will fill.
In a previous life, over at Moparts, I got into a HUGE argument about "how big" was acceptable. I can assure you that a 1/8" hole is NOT gonna adversely affect the system. Many factory bleeds are larger than that.
I agree, I put bleed holes in mine as well. My system works flawlessly. I usually use a 3/8" hole positioned opposite one another on the ring of the stat.
I'll bet on some cold days, your thermostat never opens.... you're just trying to bleed a little air.. lol

When filling an empty cooling system, the bleed hole allows air to get past the thermostat, which usually will trap an air bubble until the thermostat opens, the trapped bubble will usually "surge" a load of coolant out the rad filler, wasting a ton of coolant, but also allows the engine to overheat to some degree, while its waiting for that opening...
is just way better to vent first,, can also take the top (intake manifold hose) heater hose off, and vent there while filling.
I know Im gonna sound stupid here, but they say there are no stupid questions.. but what is the purpose of putting a 'bleed hole' in the ring of the stat? Looking for some education here lol

Running without a thermostat will not give your radiator a fighting chance to cool down the fluid you have in it. Try running a 160 stat before you try running nothing. Make sure you run a water/coolant mix ,the water with help activate the coolant.
