2e running cold - new info!

Whats my claim? That drilling a hole in the plate of the
thermo can effectively raise the operating temperature of a the car?
Have you tried it? Cause I have....

No, your claim is that the thermostat relies on system pressure to open it.

 

No you mis understood what I was trying to say.

 

That's pretty hard to misunderstand.
"Yes it does. The cooling system does use the 18 pounds of
pressure to help open the thermostat."
What were you trying to say here?
"The thermostats work off of water pressure as well as temp"
And here?

 

This has got to be a joke surely.

The pressure cap blows off pressure at 1.2 bar, that's 17.5 psi! How the hell is the system pressure going to open the thermostat when all the coolant is pissing over the engine bay!

 

He's logged off to go and read "The Big Book Of How Cars Work", by Fisher Price.

 

I guess I must be exceptionally accurate in my wording otherwise the not so insightful might get offended.



So shall i rephrase?:



The SYSTEM needs pressure in order for the function of the thermostat
to be effective. The thermostat will NOT open in a system with no
pressure. Hence the statement, the thermostat needs pressure in order
for the thermostat to open and become apart of the functioning cooling
system.



Once pressure has been obtained in the system, hot water will start to
flow into the radiator until the fluid in the radiator reaches the
tempurature at which the thermostat opens allowing the water pump
to mix the cooler fluid from the radiator into the main part of the
system in order to maintain a certain temperature within the system as
a whole.



Any problems with that?

So where does the 3mm hole need to be?

 

Yes.

The thermostat will open in a car with no pressure. Just the same as it'll open in a pan of water with no pressure.

I really think you're getting yourself a bit mixed up here......

 

On the bottom of the expansion tank.

 

No your just trying to find a way to burn me here at whatever
cost. The thermostats FUNCTION will not become effective in a
system with no pressure. and btw, it doesnt open up very much either.

 

Ask Santa for..........

 

I'm not trying to burn you at any cost - just trying to get you to admit that you're totally wrong, but you obviously aren't man enough to do it.....

 

The reason you don't want the coolant to boil is because this forms gas bubbles in the system, which don't have the same cooling properties as the coolant that they are forcing out of the way.

Where the bubbles form, you may as well not have any coolant.

 

And this is why I HATE STUPID PEOPLE

 

OK. Then go outside, start your car, take the cap off, put your
hand on bottom hose and tell me how long it takes for that
thermostat to open. Go ahead. Try it. Dont take my word for it.
Prove me wrong. Then come back on here and tell everyone how long it
took for your thermo to open up with no pressure in the system.

I'll give you an even better exercise. Take 1 VW thermostat, place it in a pan of water, and boil it on the cooker - does the stat open? yes it does, and it wont need any pressure.

 

The thermostat doesn't do its job properly without the expansion tank
cap on so it must use pressure to operate.

The thermostat doesn't do its job properly without petrol in the fuel tank
so it must use petrol to operate.

 

Yes but your failing to recognise that without pressure in the system
the thermo never gets introduced to enough hot water to make it open.



So in order for the thermostat to operate properly within the system, it needs pressure. Plain fact mate!!!

ok ok ok but how does this solve my problem?
