i am thinking about drilling a hole in my T-Stat to keep it from ...air locking... are there any problems that i might fine later by doing this? carbed 5.o...roller motor...180 T-Stat. ......
...and that is???...take 2 and call someone in the morning... ...wouldn't you have to pull the T-Stat every time you drained the water for some reason?? ... ...
The asprin trick is to put 2 asprin (or break one in half) in the thermostat. Force the therostat open and gently let it close on the asprin. This will hold the thermostat open while you fill the cooling system and the air will self bleed on start up. The asprin will disolve and the thermostat will work as intended. The hole trick works to but is not as fast and easy. Just remember to use a small hole, you only need enough to bleed the air on initial start up. Dave
I put the hole in my Grabber T-stat ... and also in the T-Stat I just put in the F150 ... Frank ... I have the same setup ... roller motor ... carb ... 180 T-stat .... and my gauge never goes above 180/185 ...
You can also buy a Thermostat with a integrated bleeder valve. I use a tool that pulls a vacuum on the system by using shop air. Allows you to check for leaks before you install coolant. After your satisfied there are no leaks you drop a hose in the coolant jug and flip a lever and the vacuum inside the cooling system draws the coolant in and prevents air locks.
Well, my new T-stat came with an air bleeder hole already in it, so I see no point in drilling one...
I honestly have never had a problem with air on windsor fords. Other applications, yes, but not windsor fords.
