A thermostat works using a 'WAX MOTOR'. Inside the copper cylinder, hiding in the middle, is a powerful THERMO-EXPANSIVE WAX. Inside the wax motor cylinder is also a piston. Hot water heats the copper, then the wax, which pushes on the piston, which pushes against the tstat's water valve closer spring
@@NickG You didnt answer my question. A hole in the thermostat to release air in the cooling system? Air from where? Release air from the block to the radiator and back again?
To drill a small hole on the MotoRoad FailSafe thermostat... could be a good idea in a CHEVY ASTRO 95?
Thanks for watching. A small hole will help Burp the air out. Long story short….. it won’t hurt.

Good to know. Thanks
These fail safe Thermostats fail all the time! Mine lasted 2 days!! I'm replacing this with a regular thermostat.
Thanks for watching, Yea I haven't had one last more than a year. but I don't have to worry about the kids melting the motor down.
Nice job Nick.I guess those fail safe thermostats DO work...
Dan Hambrick yea they work. They fail often. But I pull the thermostat out once a year to flush the block any way
You say that you drill a 1/16" hole through the thermostat flange to let air out?
Good catch, I used an 1/8 bit. But size don’t really matter (or so I keep hearing). I wouldn’t use anything over1/4. Thanks for watching.

Sorry, it lets air from the block to pass through to the radiator. It makes it easier to bleed the system
@@NickG
And how does this exactly bleed the cooling system of air when there should not be any?😀
Every time you open the system up (like to flush it out) you introduce air into the system.
I'm gathering you have chickens?
Mike Greeley yeah buddy
Yea, My yard is infested with them. No matter how many I eat they always seem to come back.
