- In this Video, I explained about an important thing I found out that took us 6 Months scratching our heads.
Our Car / Truck Water Pump keep loosing Coolant + Wet around the Water Pump due to this.
I hope that this will help someone out before buying a Thermostat !!! - Auta a dopravní prostředky

Thanks for the info. Hadn't thought about excess pressure from no hole in the t-stat damaging anything.
+Bryan Duncan - In the long run, it will damage your *Head Gasket* for sure, if you do long trips or long drive to and from your work!
@Bryan Duncan - Look up the other post... He too having the same issues... @Greg Mccarter
- He too finding the Cheap Thermostats is damaging his Head Gasket.
Been working on an 85 cj7 and I’m nervous about having burped it. I worked as much air out as I could but nervous it’s not enough. Had a buddy telling me drill a hole and you won’t have to worry about burping it. Gonna do this hopefully it all goes well. Thank you.
You welcome. Here is a Video I did way back with By-Pass, check it out: czcams.com/video/fgUYh6PVVj0/video.html
Yeah, I have been using fail safe ones for years.
+oxmanagain - Cool, at least you are aware of them :))))) - Unfortunately, not too many People does ://. I was stupid 6+ months ago, LOL
Thanks for the info in the burp hole. I modded my Veloster from 180deg to 160deg tstat, & the 160 was without the hole. Wondered if it needed it, & if just drilling a small hole would work.
YES, drill a small hole in it ASAP. If the Thermostat failed in the future and you are not aware. It will caused "pressure" in your Engine when hot. Once pressure built up and you do not change ASAP.... It will create Head Gasket Leaks, which lead to Head Gasket Failure. NOTE: No one in the World put these 2+2 together... Because of my past experience, I was able to put 2+2 together.
If I live in Warm / Hot Weather... I would take it out completely. The purpose to have the thermostat in the Engine, is to have the Engine Warm Up and to have Heat during Winter. The Manufacture call that Hole " Failed Safe ". Now you know why they name that hole " Failed Safe Hole ".
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

Thanks Google! 😂❤️😂❤️😂❤️😂❤️😂❤️
I drill a hole in them every time I change one and if you get that little piece of metal in that hole that they call a jiggled to let air out of you system !
I have a question the fail safe is it suppose to open and lock in the open position or does it mean its still running hot
It's still hot. The meaning of the "Fail Safe" is when the Thermostat failed, there's someway to release the built-up pressure. That way if doesn't shut down the Engine because it's too hot, or kill the Head Gasket. Believe it or not, this little "Fail Safe Hole " is really important. NOTE: If you are in the Hot Weather all the time, like Florida or California or Texas... You can run your Car / Truck without the Thermostat and your Car / Truck Engine will last a long time.
This works real good on older veh. pre 1996 , not so good on all OBD2 type ecm veh.1997 on up.
OBD2 system will set code P0128 (Coolant Temperature Below Thermostat Regulating Temperature)
when this code hits the ECM you could have a problem with A/C shut down...
that being said, I drill A 1/8" hole on all thermastats on my classic car builds.
just saying
I have no problems on my Dad's Truck. His is a 2001 and it's doing fine. Only problem is that we live in New Hampshire, I put the Thermostat back in Winter for Heat and take it out in Summer. It's doing really good. Engine NEVER gets HOT in the Summer and great for long trips.
I just wanna know if the hole should be at the top or bottom when u install...... I remember learning the direction matter
They only go ONE-WAY. They are made to sit in one way only.
he was asking if the weep hole should be oriented toward the top or bottom of the hole, the answer is that it doesn't matter, it would still push through coolant which is the important part
Peter Sibbio hole at the top lets the air bubble out better.
I have a I 6 ... 3.0 L Lexus . The unbreakable cast iron block ( don't make them like this anymore ) 300 K to 400 K engine . They say blow off hole should be at the highest point off the ground . Has anyone heard this before ???
i saw in one video that it should be on top so the air bubbles in the engine block could be purged making the cooling more efficient, but not too cool. The optimal temp for the intake temps are around 85 degrees since fuel cools the intake manifold as it evaporates. If the intake manifold is too cold it's not gonna make the fuel mix with the air perfectly and will be difficult to hit the proper stoichiometric ratio to make the best combustion. It will run, but similar to an engine from a cold start, the ecu will need to release more fuel to do the same thing. It's like trying to make instant coffee using cold water.
Can you say , “I’m hunting wabbits”

Heater cores on a classic car help cool the engine down better than getting rid of the heater.
:/
GM AC Delco T stats do not generally come with a peep hole in them. At least the early 90s didn't. If one fills the system with the proper concentration then allows the engine to run with the radiator cap off (watching the coolant mix cycle) air will force it's way out of the system thru the radiator cap opening. As the level drops add coolant mix. Be sure your overflow is at proper level as well. This will remove air from system.
Hi, This Video is about " Failed Safe ". I have heard many stories about when the Thermostat Failure and it created build-up pressure, which later damages would be head gasket. NOTE: Filling your Reservoir / Over flow Tank is part of maintenance. Even if you filled everything, your System still doesn't have a "Failed Safe" unless it has this "Hole" built-in or drilled. YES... I am taking from experiencing. This CHEAP thermostat from "STANT" doesn't have a hole in it. After 6 Months of usage... Our Head Gasket got leaks..... I have a Video on Bar's Leaks Head Gasket Repair on my Channel if you want to check that out.
thanks for sharing the info for the ppl that didn't know
Elmer Fud........?
*You "scwewy wabbit" !!! 😂😂😂😂😂😂😂
Cool voice haha I'm not being mean.
LOL. Thankx! 😂😂😂😂😂😂😂
😂
😂😂😂😂
that hole does not mean it's a fail safe
Of course not if you are going to count LAZY USERS not taking care of their own car or changing Coolant + Clogs + Others...
*BTW, you have a very low level of understanding things!*
